Atherosclerotic valve insufficiency (lat. Insufficiens valvularum atheroscleroticarum; synonym: mitral insufficiency or aortic regurgitant insufficiency due to disorders of the mitral or aortic valve, regurgitation of the aortic valves due to atherosclerosis, mitral-aortic insufficiency, mitral or aortic valve disease due to atherosclerosis) is a heart disease, expressive in the expansion of the valve opening of the mitral and/or aortic valves due to pathological changes leading to disruption of their function and reverse flow of blood from the left ventricle to the left atrium and/or from the aorta to the left ventricle.\n\nThe development of valve insufficiency is based on degenerative -dystrophic process, which is caused by a transient impairment of the motor ability of the valve leaflets. Due to the pathological effect of metabolic products on the valve leaflets, their color may change. The most common forms of this disease are mitral and aortic valve insufficiency. Promoting development is not enough. Atheroscl. valves can be caused by infectious and allergic lesions of the valvular apparatus of the heart, intoxication, and congenital heart defects. Infectious lesions are most often the cause of the development of mitral heart defects. Healthy valve muscle is under the influence of the sympathetic nervous system, which regulates and stimulates the functioning of the valve. After parasympathetic stimulation of such diseases, the level of “stress hormone” increases, blood pressure rises and cardiac instability appears. Clinical manifestations of mitral regurgitation, as a rule, occur against the background of severe left ventricular hypertension, which occurs as a result of a decrease in the degree of regurgitation and deterioration of hemodynamics in the pulmonary circulation. Auroral (nocturnal) form of cardiac asthma, periodic attacks of chest pain, accompanied by symptoms of valve dysfunction, fainting, are the main signs of mitral regurgitation.
