Aortosclerosis

Aortosclerosis or atherosclerosis of the aorta is chronic illness, which is based on an increase in the amount of connective tissue in the aortic wall and the formation of atherosclerotic plaques on it.

Possible causes of aortic atherosclerosis

The immediate causes of the development of atherosclerotic lesions of the aorta and other vessels have not been identified to this day.

Risk factors for the development of aortosclerosis include the presence of increased blood pressure, age over 40 years, male gender. Atherosclerosis of the aorta and other vessels is more common in smoking people, with excess weight and low levels physical activity.

Additional factors that increase the likelihood of developing atherosclerosis include constant nervous tension, presence of diabetes mellitus, family history, some psychological characteristics.

The main mechanism for the development of aortosclerosis and other localizations of atherosclerosis is a violation fat metabolism in organism.

Main symptoms of aortic atherosclerosis

The main symptoms of aortosclerosis will depend on the stage of development of the disease and the level of damage to the aorta.

In the so-called preclinical phase of atherosclerosis, there are no changes in blood vessels. During this period, disorders of lipid (fat) metabolism and some other changes can be detected. The results of a thorough examination allow us to draw a conclusion about the initial stage of the formation of the pathological process and take measures to prevent vascular damage.

During the period clinical manifestations symptoms of aortosclerosis will depend, first of all, on the specific localization of the process in the aorta.

Defeat thoracic aorta - thoracic aortosclerosis - manifests itself as fairly intense paroxysmal pain behind the sternum. This pain has a burning or pressing nature and can radiate to the arms, back, neck, or abdomen (its upper part). When taking nitroglycerin, this pain does not decrease.

Atherosclerosis(from the Greek athera - gruel and sclerosis Sclerosis- compaction of a tissue or organ caused by the death of parenchyma elements (due to inflammation, circulatory disorders, metabolic disorders, age-related changes) and their replacement with mature connective tissue, sometimes with subsequent wrinkling.) - the most common chronic Chronic- long-lasting, incessant, protracted process, occurring either constantly or with periodic improvements in the condition. arterial disease Arteries- blood vessels carrying oxygen-enriched (arterial) blood from the heart to all organs and tissues of the body (only the pulmonary arteries carry venous blood)... with the formation of single and multiple foci of lipid, mainly cholesterol deposits - plaques in the inner lining of the arteries.

Subsequent growth of connective tissue in it Connective tissue- one of the main groups of tissue from which bones, cartilage, adipose tissue, blood, lymph, ligaments, tendons, etc. are formed (sclerosis) and the deposition of calcium in the walls of the vessel Vessels(in anatomy) - in humans and animals there are hollow tubes through which blood (blood vessels) and lymph (lymphatic vessels) move. lead to deformation and narrowing of its lumen up to complete blockage of the artery. This causes insufficient blood supply to the organ Organ- a part of the body that performs a specific function (for example, heart, liver).. fed through the affected artery. In addition, acute blockage (occlusion) of the artery lumen or thrombus is possible Thrombus- a blood (lymph) clot in a blood (lymphatic) vessel.. or (much less often) the contents of a disintegrated plaque, or both at the same time, which leads to the formation of foci of necrosis Necrosis- tissue necrosis under the influence of circulatory disorders, chemical or thermal effects, trauma, etc. The necrosis zone has clear boundaries, is subsequently rejected or undergoes purulent melting; A scar forms at the site of the tissue defect. (heart attack) or gangrene in the organ that is fed by this artery.

Treatment of atherosclerosis

Atherosclerosis is a chronic disease that affects large and medium-sized arteries. With this disease, lipoproteins are deposited in the inner lining of the arteries. Subsequently, connective tissue grows in these places in the form atherosclerotic plaques.

Atherosclerosis- this is the “plague” of the 20th century. Poor nutrition, sedentary lifestyle, stress - all these are prerequisites for the occurrence of atherosclerosis. Atherosclerosis is a disease that affects main (large) vessels. In this case, cholesterol is deposited in the vessel wall, resulting in an atherosclerotic plaque that narrows the lumen of the vessel. This leads to a significant decrease in blood flow through the affected vessel, and the degree of reduction in blood flow is usually proportional to the degree of stenosis (narrowing) of the vessel. Often, atherosclerotic plaques can rupture, resulting in a defect in the cap of the plaque.

Atherosclerosis can affect not only such large vessels as the aorta and pulmonary arteries, but also smaller coronary (supplying the heart muscle) arteries, cerebral and renal vessels.

Risk factors for atherosclerosis.

According to statistics, 60% of Russians have cholesterol levels in their blood above normal, and 20% have extremely high level cholesterol.

According to numerous medical studies, factors contributing to the development of atherosclerosis include the following:

Atherosclerosis of the lungs

Changes in elastic cover inside aortas and arteries and their small branches, which arise due to lipid metabolism disorders, cholesterol deposition, and the appearance of fibrous plaques impair blood circulation in the body and cause atherosclerosis. The walls of the vessel change, and the metabolism of the main substance and protein is disrupted.

Atherosclerosis of the lungs appears after 40 years. In this case, a cough occurs, sometimes with blood, shortness of breath is noted, all this is associated with the occurrence of pressure, stagnation in the lung tissues due to impaired circulatory metabolism in the organ. In this case, you need to consult a doctor.

Atherosclerosis of the aorta of the lungs

Atherosclerosis of the pulmonary arteries is a serious disease. It is accompanied pulmonary hypertension. Patients experience hypertrophy of the medial lining of the artery, and its inner lining becomes thicker, and the formation of atheromas accelerates. Almost half of the population over 50 years of age suffers from pulmonary atherosclerosis.

Atherosclerosis of the lungs in the pulmonary circulation, this in the arteries and their small branches is of two types:

primary atherosclerosis, these are patients with normal blood pressure;
secondary atherosclerosis is observed in patients with high blood pressure.

The first type is rare already at 40 years of age and very common at 70, and the second is associated with increased pressure in the arteries of the lungs if there is a narrowing of the left atrioventricular orifice, with pleural cords and primary pulmonary hypertension.

Atherosclerosis of the lungs also affects small branches of the artery. In this case, the patient has a bluish tint of the skin turning into black - cyanosis. When engaged in work, even small ones, an increase in cyanosis is noted, but if the patient also has good anemia, then cyanosis may not be present.

Treatment of atherosclerosis: symptoms and types

Atherosclerosis - main reason, disrupting the blood supply to tissues and organs. How important is proper blood circulation, see Blood circulation. Atherosclerosis (and the diseases caused by it) is the number one killer of people! Therefore, we need to talk in detail about the prevention and treatment of atherosclerosis.

There is an idea of atherosclerosis as a manifestation of old age. Sometimes atherosclerosis is associated with absent-mindedness or forgetfulness. Both are wrong. Atherosclerosis can be present in young people and absent in old age. This is the first thing. Secondly, the signs of the disease are much more diverse, because it can affect the body literally from head to toe.
Sclerosis literally means “hardening”. It can develop in the lung tissue, then it is pneumosclerosis, in the heart muscle - cardiosclerosis, in the kidneys - nephrosclerosis, and even in the bones - osteosclerosis, and, finally, a special form of damage to large arteries - atherosclerosis.

Atherosclerosis is a metabolic disorder in which the content of a fat-like substance, cholesterol, increases in the blood. The formation of a compound called lipoprotein (fat + protein) that penetrates the artery wall also increases. At the same time, cholesterol accumulates in it, followed by either liming of plaques or their ulceration. The risk of occurrence and development of atherosclerosis increases with age.

Atherosclerosis - Risk factors.

The development of atherosclerosis may increase for the following reasons.
1. Nervous stress. Stress.
2. Hereditary disorders of the activity of certain glands.
3. Atherosclerosis increases under the influence of dietary errors. Overeating, especially animal fats, food products rich in cholesterol (eggs, liver, animal oils, etc.) - everything that leads to obesity.
4. Smoking also provokes atherosclerosis.

Atherosclerosis - Stages of development.

Diffuse atherosclerosis or cardiosclerosis is the formation of cholesterol plaques on the damaged inner wall of the arteries, due to connective tissue, which leads to poor circulation. With prolonged oxygen starvation, multifocal partial necrosis of organ cells and replacement with scar tissue occurs.

Causes

Scientists have determined that the structure of the plaque of cerebral atherosclerosis is practically no different from the cholesterol formation of the arteries of the heart or limbs. Therefore, diffuse atherosclerosis can be called a nonspecific lesion inner shell vessel with an inflammatory component. The presence of macrophages (cells that actively capture and process bacteria, remains of tissue necrosis, and other foreign particles) is confirmed by histological examination.

The main cause of the disease is sclerotic damage to the blood vessels that supply the organ with blood. However, the following factors can have a positive effect on the development of diffuse atherosclerosis:

ischemic disease;
heart disease;
hypertension;
arrhythmia;
intoxication, exposure to heavy metal compounds;
rheumatism;
myocardial inflammation;
dystrophic changes in the myocardium;
high sugar;
overweight;
injuries, operations;
alcoholism;
smoking;
stress;
age-related changes;
heredity;
lack of movement.

Diagnostics

Diffuse atherosclerosis requires a complete comprehensive diagnosis of the body. The following studies are usually suggested:

Analysis of complaints, examination of the patient. Identification of the cause, time of onset of symptoms. Collecting information about living conditions and the presence of bad habits.
Biochemical, general blood test. Allows you to determine the general health of the patient, the presence of chronic diseases, as well as the content of “good” and “harmful” cholesterol.
ECG. Determines the presence of arrhythmia, heart rate, as well as functional changes in the heart.
Ultrasound, MRI. Evaluates the performance of internal organs.

Symptoms of the development of ischemia of various organs

Depending on the location of sclerotic foci that disrupt the blood circulation of organs, the symptoms of the development of diffuse atherosclerosis differ significantly. Let's consider complex cases.

Features of cardiac pathology

Diffuse atherosclerosis affects the coronary vessels, disrupting the blood circulation of the heart muscle, which is very sensitive to lack of oxygen. Areas of muscle cells long time those that do not receive nutrients and oxygen die. Their place is taken connective tissue, forming scars.

Long-term coronary insufficiency can cause diffuse small-focal cardiosclerosis, a severe pathology that involves the appearance of scars over the entire surface of the heart muscle. The valves become deformed and the functions of the heart are impaired.

There is a gradual formation of foci of necrosis, with the growth of which the patient’s condition worsens. Metabolism is disrupted, small areas of the myocardium atrophy, and dystrophic changes in muscle tissue cells occur.

The following symptoms are characteristic of cardiosclerosis:

pain in the heart area after exercise or stress. Usually the attack goes away within 5-7 minutes;
difficulty breathing, feeling of chest fullness;
weakness;
tachycardia;
nausea.

These are signs of a short-term circulatory disorder in the heart muscle.

An attack of acute heart pain requires an emergency call to the ambulance medical care to prevent the development of myocardial infarction.

If blood flow is not restored for a long time, serious complications develop, life threatening sick.

When a large area of the myocardium is damaged, the following clinical manifestations develop:

Dyspnea. Characterized by impaired ability of the left ventricular muscles to contract. First appears after physical exertion, then in the normal state;
Paroxysmal dull pain in the heart area, right hypochondrium. Accompanied by hydrothorax, swelling, dropsy;
"Cardiac cough." At an early stage, a dry cough occurs after physical exertion, and with severe pathology - even at rest;
Decreased performance, apathy, muscle weakness;
Edema lower limbs In the evening. In the morning they practically disappear. Start from the ankles, rise to the shins, thighs;
Cardiac arrhythmia. The disease contributes to the development of various forms of arrhythmia due to impaired activity of the heart muscle;
Blue skin color (cyanosis). The lip area is affected with extensive myocardial damage;
Brittleness, hair loss, deformation of nails due to poor blood supply;
Increased skin pigmentation.

At the initial stage of cardiosclerosis, there are no clinical manifestations of the disease. With extensive myocardial damage, many symptoms may appear simultaneously. Signs of heart failure, liver and lung diseases may occur.

Features of brain pathology

Diagnosed diffuse cerebral atherosclerosis implies that the concentration of cholesterol is increased, atherosclerotic plaques are present in the aorta, coronary, carotid or iliac arteries.

Sclerotic changes in cerebral vessels for a long time go unnoticed. The blood supply to the brain is produced by four large arteries - two carotid, two vertebral. The lack of blood flow of one or two of them is taken over by healthy arteries until the blood supply to the brain drops to a critical point.

The first initial stage of the disease begins. It is characterized by the following symptoms:

balance disorders;
noise in ears;
headache;
confusion, loss of consciousness;
increased weakness, fatigue;
paralysis of one side of the body;
vision impairment or loss;
numbness various parts bodies;
coordination problems;
speech disorders.

All these manifestations confirm the pathological narrowing of cerebral vessels. If at the same time three signs of these manifestations continue for more than a day, they speak of a transient ischemic attack - an emergency condition requiring immediate medical attention.

At the second stage of the disease, in addition to the initial symptoms, the following neurological disorders are added:

emotional instability;
numbness, swelling of the legs;
tingling of the face, limbs;
isolation;
suspiciousness;
unclear speech;
unsure gait;
hand trembling.

The patient suffers from depression, apathy, and uncertainty.

The third, most dangerous stage of dementia is characterized by signs of mental disorder and loss of awareness. Possible:

memory loss;
epileptic seizures;
causeless laughter, crying, fears;
loss of speech or motor activity;
paralysis;
stroke.

Such patients require constant monitoring, as they have completely lost the ability to independently care.

Patients lose jobs that require concentration or quick reactions. Coordination of movements is impaired, intelligence decreases. Trembling often develops upper limbs. In view of such violations, medical examination assigns patients the appropriate disability group.

When hypertension is added to atherosclerotic pathology, the risk of transient ischemic attacks increases, and in diabetes mellitus, ischemic or hemorrhagic stroke is also high.

Due to plaque blocking the blood flow of the arteries supplying the brain, the following develops:

internal cerebral hemorrhage (hemorrhagic stroke);
transient disorders cerebral circulation, that is, microstrokes;
myocardial infarction;
strokes;
gangrene of the lower extremities;
stenosis, aortic aneurysm.

Any of these diseases is difficult to treat and usually leads to disability or death of the patient.

Features of the disease of the lower extremities

Diffuse atherosclerosis of the arteries of the lower extremities is a consequence of hardening of peripheral vessels of medium and large size. The aorta, superficial femoral, popliteal artery, which leads to disruption of normal blood flow in the lower extremities.

Signs of the disease are:

intermittent claudication - aggravated by walking;
lack of pulse (at the ankle or thigh);
numbness of the legs;
lack of control over limbs – “alien legs”;
trophic manifestations (separation of nails; ulcers on fingers, heels);
skin cyanosis, trophic ulcers, gangrene.

Depending on the degree of damage to the arteries, there are:

Non-stenotic atherosclerosis is the initial stage of the disease. There are almost no symptoms - slight leg fatigue. The cholesterol plaque covers no more than 50% of the lumen.
Stenosis is the stage at which symptoms appear. The artery is less than 50% patency. The structure of the cholesterol plaque changes - calcium salts settle and it hardens.
Wall-occlusive atherosclerosis is the most dangerous stage. The blood flow is completely blocked.

Surgical intervention

There are general patterns of conduct surgical operations, depend on the degree of development and localization of sclerosis foci:

For diffuse atherosclerosis of the heart vessels, operations are performed:

stenting of coronary arteries - an artificial stent is inserted, expanding the internal lumen of the artery to the required size;
bypass - organization of lateral blood flow bypassing the sclerotic area of the artery;
prosthetics – replacement of the affected area of the vessel with grafts from the patient’s saphenous vein.

Open operations on cerebral vessels are difficult due to problematic access to the lesion. The first place is occupied by intravascular minimally invasive methods of endovascular surgery: balloon angioplasty, stenting, which allow restoring blood flow to damaged vessels. Prosthetics of cerebral vessels is not performed due to its great complexity and insufficient availability of necessary medical equipment.
To avoid the development of gangrene, balloon angioplasty and stenting methods are used; if they are ineffective, bypass surgery is performed on the affected vessels.

Despite the growth in the skill of surgeons and the development of technical equipment in medical institutions, complications after open operations often occur.

Conservative treatment

Therapy of diffuse atherosclerosis eliminates ischemic organ damage and has the following directions:

Normalization of the functions of the cardiovascular system.
Reducing the level of “bad” cholesterol, normalizing lipid metabolism.
Preventing severe complications.

For this purpose, the following groups of drugs are used:

(Nitroglycerin, Nitrosorbide). They have an anti-ischemic effect due to the expansion of arteries, increasing blood circulation.
(Anaprilin). They reduce the need for oxygen, reduce the strength and frequency of heart contractions. Lowers blood pressure and improves well-being during physical activity.
(Nifedipine, Diltiazem). They reduce the oxygen demand of cardiac muscle cells and lower blood pressure.

The choice of drugs, dose and duration of administration is prescribed by the doctor based on the results of a comprehensive medical examination taking into account concomitant diseases.

Treatment is carried out in long courses with short breaks during remissions. Long-term use of medications negatively affects organs gastrointestinal tract, liver.

Prevention

To prevent the development of atherosclerosis, it is necessary to give up bad habits, go to healthy image life, including:

a full night's sleep, gentle work and rest;
morning exercises, feasible physical activity, walks fresh air up to several hours/day, simple gardening work;
positive emotions, stress management. It is recommended to take soothing herbal decoctions and relaxing pine baths;
fight against smoking, alcoholism;
blood pressure control (not higher than 140/90 mmHg), treatment of hypertension;
monitoring the presence of sugar (for patients with diabetes);
control cholesterol levels, regular consultations with a neurologist;
taking courses of sanatorium-resort treatment, hirudotherapy, herbal medicine, homeopathic or traditional methods of treatment in consultation with the attending physician.
transition to a healthy diet.

Diffuse atherosclerosis is a dangerous type of disease, the successful treatment of which requires adherence to a special diet.

This type of nutrition includes:

limiting the calorie content of food - it should be 2700-3000 calories/day (approximately: protein - 100 g, fat - 50-60 g, carbohydrates - 350 g);
complete exclusion flour products, fatty meats, meat, mushroom, fish broths, fatty dairy products, hot seasonings, chocolate;
consumption of low-fat fish, poultry, seafood, vegetable, milk soups, buckwheat, barley, oatmeal, low-fat dairy products, an abundance of vegetables, fruits, berries, herbs.

Despite the high calorie content, it is beneficial to consume flaxseed and olive oil, which contain polyunsaturated fatty acids of the Omega group. Regular intake of this oil helps cleanse, strengthen the bloodstream, and normalize metabolic processes.

Blockage of blood vessels with cholesterol plaques can affect any organ. Pathology has a depressing effect on its work, causing various complications. Atherosclerosis of the pulmonary vessels develops as a result of congestive processes caused by damage to the pulmonary arteries.

The main reason for its appearance is a violation of lipid metabolism and deterioration in the elasticity of vascular walls. The disease is dangerous due to oxygen starvation and subsequent tissue necrosis. Most often, the disease develops in heavy smokers, mainly males.

Atherosclerosis of the lungs appears due to lipid metabolism disorders and deterioration of the elasticity of vascular walls

Atherosclerosis of the lungs is accompanied by an increase in the amount of cholesterol in the body. This occurs as a result of a violation metabolic processes. The substance is no longer excreted by the cells of the liver and kidneys, and its excess is deposited on the walls of blood vessels.

As cholesterol plaques grow, the lumen of the blood vessels gradually narrows. Blood stops circulating at the same rate. As a result, the damaged organ does not receive the required amount of oxygen. The prerequisites for the development of atherosclerosis of the pulmonary vessels are the following:

disruption of the endocrine system;
increased pressure in the lungs;
vascular injury;
diabetes;
unbalanced diet;
inflammatory processes in the respiratory system;
excess weight;
limited physical activity;
smoking and alcohol abuse.

In the presence of one of the provoking factors, the likelihood of developing the disease is not as high as in the case of their combination. The formation of atherosclerotic plaques occurs gradually. This process is not always noticed by the patient. The process of damage to the vessels of the pulmonary system is also called diffuse pulmonary atherosclerosis.

How the disease develops

Pulmonary atherosclerosis develops in several stages. Each of them is accompanied by certain symptoms. At the initial stage, the chances of coping with the disease are the highest.

In advanced cases, atherosclerosis is characterized by severity and is difficult to respond to drug therapy. The disease develops according to the following scheme:

Changes internal structure vessels. As part of the diagnostic examination, microthrombi are detected and signs of endothelial damage are observed.
Due to improper functioning of enzymes, cholesterol accumulates on the inner surface of blood vessels. The smooth muscle tissue of blood vessels absorbs lipids. Fat spots and light stripes are visualized in this area.
Localized in the area where bad cholesterol is deposited fibrous tissue, which forms atherosclerotic plaques.
The affected area becomes wider. The resulting plaques interfere with the full passage of blood through the vessels. The patient notices the appearance of ulcers and bruises on the skin surface.
At an advanced stage of the disease, the area of damage becomes even more extensive. The functioning of several organs is impaired.

On a note! According to statistics, in males, atherosclerosis is caused by age-related changes, appears 10 years earlier than in women.

Symptoms

On initial stages severe symptoms does not have a disease. They appear when there is severe deformation of blood vessels. The primary signs of this disease affect the basal branch of the lungs, which leads to a change in the hilar pulmonary pattern. Among the most common signs of the disease are:

fast fatiguability;
severe cough with blood discharge;
blue discoloration of the skin surface in the sternum area;
shortness of breath;
decreased pressure in the pulmonary sac;
increase in the volume of veins in the neck;
pain in the sternum;
wheezing in the lungs.

Diagnostics

Questioning the patient makes it possible to make a diagnosis only in the last stages of atherosclerosis. Therefore, it is not recommended to refuse general diagnostic procedures. They help to identify pathology at the asymptomatic stage of the disease.

Suspicion of the presence vascular pathologies occurs when there is increased pressure in the pulmonary arteries. Diagnostics include the following:

taking a general clinical blood test;
detection of cholesterol levels and lipid profile patient;
X-ray of the lungs in different projections;
ultrasound examination of the cardiopulmonary system with determination of blood flow in the aortas;
conducting MRI or computed tomography;
contrast angiography.

Treatment

Diffuse atherosclerosis is eliminated by a set of measures. Treatment is carried out by a vascular surgeon or cardiologist. During development respiratory failure Consultation with a pulmonologist is required. Therapy against atherosclerosis includes the following aspects:

A diet is selected that involves excluding foods high in cholesterol from the diet.
Appointed physiotherapy, promoting weight loss.
Accepted medications, lowering cholesterol and preventing further growth of atherosclerotic plaques.
If necessary, hormonal levels are normalized.
Measures are being taken to restore respiratory function.

Medications

The goal of drug therapy is to normalize the patient’s well-being by reducing the severity of the main symptoms. The basis of therapy is the use of statins and fibrates. Statins lower cholesterol by affecting the enzymes responsible for producing the substance.

Drugs in this group include Rosuvastatin, Lovastatin and Atorvastatin. Fibrates have a splitting effect on low-density proteins. These include drugs: Gemfibrozil and Benzafibrate.

Bile acid sequestrants allow the liver to use up more cholesterol than normal. Among these drugs are Cholesterolamine and Colestipol. Medicines containing nicotinic acid are necessary to reduce the amount of lipoproteins in the circulatory system.

Folk remedies

Facilities traditional medicine do not give the same result as medications. Sometimes they are prescribed to enhance the main therapy. The following remedies have a positive effect on the condition of blood vessels:

potato juice;
a mixture of garlic and sunflower oil;
thyme decoction;
onion juice with honey;
parsley decoction.

Complications

Lack of treatment leads to the development of complications that threaten the patient's life. The most important pathology is vascular insufficiency respiratory system. As a result of stenosis of the pulmonary vessels, atherosclerosis of the arteries of the neck develops, manifested in a narrowing of its lumen. Chronic disruption of blood supply provokes the development of ischemic disease, hypoxia and the formation of small focal sclerosis.

Prevention

Most often, pulmonary atherosclerosis develops due to an unhealthy lifestyle. Pathological processes can be prevented by taking timely measures. These include the following:

Not recommended for consumption a large number of salt, confectionery, products containing animal fats and spicy foods. Polyunsaturated fatty acids, fiber, vegetables and fruits should be included in the diet.
It is imperative to stop smoking and drinking alcoholic beverages.
In the presence of excess weight weight loss is indicated.
Moderate physical activity will help maintain vascular system in good shape.
It is extremely important to eliminate inflammatory and infectious processes in the respiratory organs in a timely manner.

Conclusion

Atherosclerosis of the pulmonary system is fraught with impaired respiratory function. The pathological process not only affects well-being, but is also a threat to life. During Taken measures allow you to avoid complications and normalize the patient’s condition.

A disease in which deposition of cholesterol plaques is observed on the endothelium of the pulmonary vessels is called pulmonary atherosclerosis. It is a chronic pathology in which there is a progressive decrease in the lumen of large vessels, disruption of the trophism of lung tissue and oxygen saturation of the blood.

Most often, the disease develops against the background of ischemic heart disease (coronary heart disease) and chronic lung diseases. The main provoking factor is high levels of lipids in the blood.

Due to insufficient oxygenation of the blood, cyanosis occurs, which is the first sign of pulmonary atherosclerosis

Key risk factors

Pathological changes in the pulmonary artery are more often diagnosed in men after 40 years of age, but recently there has been a clear trend towards more early development. The majority of patients are residents of megacities. Pulmonary atherosclerosis often develops due to the following factors:

lipid metabolism disorders accompanied by high levels of cholesterol and triglycerides in the blood;
obesity;
arterial hypertension;
smoking, alcohol abuse;
hormonal imbalance;
diabetes mellitus and other endocrine disorders.

Changes in the walls of the aorta play a major role in the development of the disease. They may be damaged as a result viral infections, autoimmune processes, genetic predisposition.

Atherosclerosis of the lungs is a pathology with a high probability of disability or fatal outcome in the absence of adequate therapy. Therefore, after 40 years of age, if you have the first signs of the disease: shortness of breath, heart pain and swelling of the legs, you should immediately consult a doctor for a comprehensive examination.

Atherosclerosis of the lungs is a serious disease that can be fatal!

Stages of the pathological process

The process of plaque formation on the walls of the arteries and aorta occurs gradually. It is customary to distinguish five stages of the disease.

Local changes in the vascular wall appear in those places where the most intense blood flow is observed, especially at the junction of the aorta with large pulmonary vessels. At this time, minor damage is observed on the endothelium, small-sized blood clots begin to form, which further increases the damage and permeability of the vascular wall. At this stage, active thrombus formation is prevented by enzymes present in the blood in sufficient quantities.
Specific enzymes become insufficient, which activates the process of deposition of atherosclerotic plaques. The structure of elastin changes, its fibers thicken. The structure of vascular smooth muscles also changes. Cells actively absorb lipids and are modified into those that will soon become the basis of the atherosclerotic process.
Connective tissue is formed in places where lipids are deposited. As it matures, it stimulates the growth of fatty plaques.
At the location of the plaques, active breakdown of lipids and collagen fibers begins. A cavity appears containing a “porridge” of fats and proteins. Such an atheromatous ulcer with “porridge” can cause the rapid formation of large blood clots.
Calcium salts begin to be deposited in the atheromatous mass. A significant portion of the aorta and smaller vessels have severely damaged areas.

Symptoms and diagnosis of the disease

The main set of signs clearly indicating pulmonary atherosclerosis was Ayres syndrome - bluish skin, a sharply increased number of red blood cells in the blood, shortness of breath and a pronounced enlargement of the heart. In this case, the degree of heart enlargement does not correspond to the general condition of the patient. Among common symptoms weakness, high fatigue, chest pain are noted; hemoptysis and swelling of the lower extremities may occur.

For diagnosis, an objective examination, auscultation, percussion of the lungs, history taking, as well as laboratory and instrumental methods examinations:

examination of the iris to identify specific atherosclerotic rings;
blood biochemistry to clarify the lipid profile;
contrast radiography of the lungs;
Ultrasound of the heart and abdominal cavity;
duplex and triplex scanning of the pulmonary artery;
CT or MRI.

Using computed tomography, it is possible to accurately diagnose atherosclerosis in the lungs in the initial stages

Treatment of pathology

Atherosclerosis of the lungs is a disease that occurs only against the background of impaired lipid metabolism. Therefore, therapeutic tactics include several stages:

correction of metabolism;
stabilization of body weight;
normalization of hormonal levels;
lowering blood cholesterol;
activation of the breakdown of fats and blood clots;
strengthening the vascular wall;
antiplatelet therapy.

All medications should be prescribed only by a doctor after a complete examination of the patient. Many products have side effects, and if used uncontrolled can impair kidney and liver function.

The main goal of treatment is to minimize the risk of developing subsequent complications

Of great importance in pulmonary atherosclerosis, especially in early stages, is given to diet. Medicines(statins, fibrates) can quickly reduce the level of lipids in the blood, but this cannot be done without nutritional correction. From your daily diet you should completely exclude foods rich in animal fats: meat, butter, whole milk. Preference should be given to fish and seafood. Numerous studies have proven their ability to reduce blood cholesterol levels by 50-65% with constant use.

In order to reduce body weight, it is necessary to limit the intake of simple carbohydrates and increase the amount of plant fiber: vegetables, fruits and herbs should be present in sufficient quantities in the diet. daily diet. To correct the lipid profile, various nutritional supplements can be taken: vitamin E, fish oil, a nicotinic acid. After the examination, the doctor may prescribe blood thinning medications.

Atherosclerosis includes:

Atherosclerosis does not include:

cerebral (we talked about the signs and symptoms of cerebral atherosclerosis of the cerebral vessels, and you will learn about the treatment of this disease);
coronary;
mesenteric;
pulmonary.

What diseases does it appear as a result of?

For some chronic diseases, the likelihood of developing this disease increases significantly:

Diabetes– contributes to the disruption of fat metabolism, and is the “starting” button for the onset of the development of atherosclerosis.
Arterial hypertension- at high blood pressure begin pathological processes increased saturation of blood vessels with fatty deposits. All this leads to the formation of plaques.
Dyslipidemia– with an increased content of cholesterol and other substances in the body, fat metabolism is disrupted and atherosclerosis develops.
Various infections– toxic microorganisms damage vascular walls, which in turn provokes atherosclerotic changes.

Kinds

Blood pressure in this disease

Atherosclerosis and hypertonic disease– if atherosclerosis is a pathological change and damage to the walls of blood vessels, the accumulation of cholesterol deposits on them and the formation of plaques, then hypertension is an unnoticed disease characterized by periodic high blood pressure, which in turn can provoke strokes and heart attacks and thicken the walls of blood vessels, smooth heart muscles.

If hypertension is nervous disease, and atherosclerosis is metabolic, then both of them are still interconnected and one can enhance the progression of the other.

Atherosclerosis and arterial hypertension - the difference between hypertension and hypertension is that hypertension is a sustained increase in blood pressure, hypertension is periodic, but both of these conditions, if they develop in parallel with atherosclerosis, lead to accelerated thickening of the walls of blood vessels, narrowing of the lumens, the formation of plaques and others destructive processes leading to strokes and heart attacks.

Other types

Mesenteric arteries– these arteries supply blood to the entire intestine; with atherosclerosis, the vessels become clogged, which can lead to ischemia. Symptoms of atherosclerosis of the mesenteric arteries are characterized by paroxysmal abdominal pain after eating, smoking or drinking alcohol. At first, the pain is short-lived, but as the disease progresses, attacks can last up to 15 minutes.
Aorta of the lungs- This is a disease that develops very slowly and does not manifest itself at first. With it, plaques form on the inner walls of the pulmonary artery, which interfere with normal tissue nutrition and complicate the supply of oxygen.
provoke this disease may poor nutrition, problems with endocrine system, sedentary lifestyle, smoking, obesity, stress, various inflammatory processes, diabetes. If left untreated, the disease can lead to pulmonary infarction and pleurisy.

Pulmonary atherosclerosis is divided into primary and secondary. Symptoms include discomfort during physical activity, unnatural skin color, causeless cough, drowsiness.
Renal arteries– a chronic disease, as a result of which the renal arteries are affected, and the development of arterial and vasorenal hypertension begins and a general malfunction of the entire urinary system occurs.
Thoracic aorta– one of the most common forms of atherosclerosis. The disease can affect the entire aorta or its individual parts. The disease does not manifest itself for a long time, changes occur in the walls of blood vessels, connective tissue grows, the artery narrows, and plaques form that disrupt the blood supply to all organs and tissues of the body.
Abdominal aorta- at atherosclerotic change vessels in the body, a pathological change in the abdominal aorta and its arterial branches may begin. There is a narrowing and insufficient saturation of blood vessels.
Abdominal pain, a feeling of fullness, belching, and nausea begin. Atherosclerosis of the abdominal aorta is similar in its symptoms to other diseases of the digestive tract, which makes its diagnosis and timely treatment difficult.

We talked in detail about all types of aortic atherosclerosis, and in this article you can familiarize yourself with the methods of treating the disease.
Lower limbs- at pathological changes, leading to narrowing of the walls of blood vessels, the formation of plaques, insufficient blood flow to the extremities, trophic processes are disrupted, which in turn can lead to the loss of the functions of the extremities, and subsequently to gangrene and inflammation.

Pathogenesis

The development of atherosclerosis is influenced by diabetes mellitus, uncontrolled use of tobacco and alcohol products, hypertension - all these factors have a significant impact on the pathogenesis of atherosclerosis.

But, perhaps, the main factor is eating low-quality, high-calorie food, which may contain dangerous fats, which are subsequently broken down into low-density lipoproteins, deposited on the walls of blood vessels, leading to the formation of plaques.

While the content of lipoproteins in the patient’s blood is low, the disease proceeds without any signs, but when changes in their composition begin, in which lipoproteins are oxidized, vasoconstriction occurs and intake significantly worsens. nutrients into organs and tissues, hence the signs of ischemia.

Main symptoms of manifestation

Hearts

One of the most susceptible organs to blood supply is the heart.. When it is violated, angina syndrome begins to appear. Periodically occurring symptoms also include:

Upper and lower limbs

Brain

Treatment

In particularly advanced cases with clinically significant atherosclerosis, surgical intervention may be required.

For drug treatment, drugs are mainly used that slow down the production of cholesterol by the liver, dilate blood vessels, or accelerate the consumption of cholesterol by the liver for normal digestion. For atherosclerosis of the extremities, physiotherapy may be indicated.

There are three main methods for surgical treatment:

Vascular prosthetics– complete replacement of the damaged vessel.
Bypass surgery– formation of a new blood line by suturing the affected vessel to a healthy one.
Angioplasty– cleaning and widening the affected area with a special catheter, which the doctor inserts through the femoral artery.

Forms of pathologies of various types

Pathological changes are divided into three types:

Fat stripes.
Fibrous plaques.
Complicated lesions.

Fatty streaks are one of the first signs of atherosclerosis. Fatty stripes are fairly soft formations and practically do not cause destructive processes in blood vessels. They are quite difficult to detect, but when stained with a preparation containing fat-soluble dyes, they become visible quite clearly.

Fibrous plaques are thickenings protruding on the surface of blood vessels. Usually begin to appear in the abdominal aorta, carotid artery, and then progress through all vessels and cause their blockage.

Complicated lesion - occurs with calcification of plaques, and subsequent necrosis. May cause thrombosis and aneurysm formation.

Conclusion

Atherosclerosis is an acquired disease with many forms and symptoms.. From the early age you need to watch your diet and bad habits to reduce the risk of its occurrence to a minimum. If, after all, you have been given such a diagnosis, do not be afraid, modern medicine There are many methods that allow, if not completely getting rid of, then stopping the progression of atherosclerosis for a long time.
