CARDIOMYOPATHY

- myocardial damage of unknown or unclear etiology, in which the dominant signs are cardiomegaly and heart failure, excluding the processes of damage to the valves, systemic and pulmonary vessels.



Clinical classification

1. Congestive (congestive) cardiomyopathy, or primary myocardial disease.

2. Hypertrophic cardiomyopathy: a) without obstruction of outflow tracts (diffuse symmetric hypertrophy); b) with obstruction of outflow tracts (local asymmetric hypertrophy, idiopathic hypertrophic subaortic stenosis).

3. Obliterating cardiomyopathy (endomyocardial fibrosis, fibroblastic eosinophilic endocarditis of Leffler, African cardiomyopathy, Becker disease).

4. Constrictive (restrictive) cardiomyopathy.



Diagnostic criteria

There are no reliable clinical criteria for cardiomyopathy.
The dominant signs are manifestations of heart failure. In some cases, the diagnosis is established only in the post-mortem examination.

Among instrumental methods of research the most valuable is echocardiography. In hypertrophic cardiomyopathy, a symptom of systolic bulging of the anterior leaflet of the mitral valve is isolated, with congestive cardiomyopathy, the trajectory of the movement of the mitral valve takes the form of a “fish mouth”.



Examples of the formulation of the diagnosis

1. Congestive cardiomyopathy; relative mitral valve insufficiency; atrial fibrillation, tachysystolic form. Nk.II-a degree.

2. Idiopathic hypertrophic subaortic stenosis. Polytopic ventricular premature beats. Nk II degree.

CARDIOMYOPATHY

  1. Cardiomyopathy. Hypertrophic cardiomyopathy (code 142.0)
    The term "cardiomyopathy" refers to a state of unknown etiology, the most important signs of which are cardiomegaly and heart failure; this name excludes heart disease resulting from valve damage, impaired coronary blood flow, and hypertension in the large and small circulation. Etiology. Clinical and anatomical forms. Prospective

  4. Cardiomyopathy
    Dilated cardiomyopathy. Idiopathic dilated cardiomyopathy is characterized by a gradual development of heart failure with symptoms of hypertrophy of the walls of all 4 chambers of the heart and dilatation of the cavities, occurring for unknown reasons (Figure 11.3, A and B). Genetic causes of the disease were found in 20% of patients, especially in individuals with familial dilated cardiomyopathy. For
  5. Cardiomyopathy
    The term "cardiomyopathy" was first used in 1957 to refer to a group of myocardial diseases of unknown etiology. In 1972, the following definition of cardiomyopathy was given: "Cardiomyopathy is an acute, subacute or chronic lesion of the heart muscle of unknown or unclear etiology, often combined with a lesion of the endocardium, and sometimes the pericardium." This definition is accepted.
  6. Cardiomyopathy.
    Cardiomyopathies are diseases of the myocardium accompanied by cardiac dysfunction. In accordance with the classification proposed by the WHO expert committee (1995), the following are distinguished: dilated cardiomyopathy; hypertrophic cardiomyopathy; restrictive cardiomyopathy; arrhythmogenic right ventricular cardiomyopathy; unclassified cardiomyopathy; specific cardiomyopathy.

  7. CARDIOMYOPATHY.
    In recent years, cardiomyopathy has attracted increasing attention from cardiologists due to the fact that they have become more frequently diagnosed and, apparently, their true frequency has increased significantly. According to WHO, the name "cardiomyopathy" refers to a narrow group of myocardial lesions of unknown etiology, the most important manifestations of which are cardiomegaly and progressive cardiac

    Etiology of cardiomyopathy • ???? Infections: - viral; - bacterial. • ???? Intoxication: - alcohol; - cocaine and other drugs. • ???? Systemic diseases: - muscular atrophy; - myotonic atrophy; - collagenosis; - sarcoidosis; - pheochromocytoma; - acromegaly; - thyrotoxicosis; - myxedema; - amyloidosis; - hemochromatosis; - primary tumor or its metastases.
  9. Tacysubo cardiomyopathy
    Definition Tacocubi cardiomyopathy is a transient balloon-like expansion of the middle part of the apex of the heart (apical ballooning), accompanied by transient regional systolic dysfunction with simultaneous hyperkinesia of the basal segments of the left ventricle in the absence of coronary artery stenotic lesions. For the first time, cardiomyopathy was also described in 1990 by Japanese researchers H. Satoh.
  10. CARDIOMYOPATHY
    Cardiomyopathy is a very common disease in cats characterized by myocardial damage, which is usually not inflammatory. Usually, cardiomyopathy develops in young cats and middle-aged animals. Often the cause of the disease is a lack of taurine in the body, or it can develop with hypothyroidism, or myocarditis. Secondary (specific) cardiomyopathies also develop.
  11. CARDIOMYOPATHY
    Another group of non-coronary myocardial lesions, the most severe of all, both in terms of diagnosis and clinical manifestations, and in terms of treatment, is cardiomyopathy. At the suggestion of W.Brigden / 1957 / and J.Goodwin / 1961 /, the term “cardiomyopathy” should be considered as independent primary forms of heart damage of unclear or controversial etiology with progressive adverse
  12. Dilated cardiomyopathy
    DILATED CARDIOMYOPATHY is a serious myocardial disease, characterized by the expansion of the cardiac cavities, a decrease in its contractility, the development of heart failure, an abnormal heart rhythm, and thromboembolism. The diagnosis of dilated cardiomyopathy is established in the presence of dilatation and systolic dysfunction of the left ventricle and in the absence of congenital heart defects,
  13. RESTRICTIVE CARDIOMYOPATHY
    Definition Restrictive cardiomyopathy is an infiltrative or fibrous myocardial lesion, which is characterized by rigid, uncompliant ventricular walls, a decrease in the filling and diastolic volume of one or both ventricles with normal or almost unchanged systolic function and wall thickness. The basis of the disease is common interstitial fibrosis.

  15. Cardiomyopathy
    This group of diseases of unknown etiology is associated with primary non-inflammatory non-coronary myocardial damage. There are hypertrophic, dilated and restrictive cardiomyopathy. In addition, there is another form of this disease - peripartal (postpartum) cardiomyopathy, which occurs between 35-36 weeks. pregnancy up to 5 - 6 months postpartum, the last
  16. Non-compact LV cardiomyopathy
    Definition Non-compact LV cardiomyopathy (isolated LV non-compactness, increased LV trabecularity, spongy myocardium) is a congenital disease characterized by severe LV trabecularity with deep interstitial slits associated with the ventricular cavity. First described by R. Engberding and F. Bender in 1984 Epidemiology The true prevalence of the disease
  17. Ischemic cardiomyopathy
    The concept of ischemic cardiomyopathy was proposed in 1969, when Raftery and colleagues identified a causal relationship between coronary artery disease and congestive cardiomyopathy. In other words, in the cases described, a marked cardiomegaly with manifestations of congestive HF was observed, as is the case with typical DCM, and only atherosclerotic lesion of the coronary arteries indicated its ischemic genesis.

    Joshua Winnie, Eugene Braunwald (Joshua Wynne, Eugene Braunwald) Cardiomyopathy Cardiomyopathy is a disease in which myocardial damage is the primary process and not the result of hypertension, congenital diseases, valvular lesions, coronary arteries, pericardium. Cardiomyopathies are not considered to be the leading pathology of the heart in Western countries, while in a number
