 Cardiomyopathy- A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
- 425 is a non-specific code that cannot be used to specify a diagnosis
Endomyocardial fibrosis- A condition characterized by the thickening of the ventricular ENDOCARDIUM and subendocardium (MYOCARDIUM), seen mostly in children and young adults in the TROPICAL CLIMATE. The fibrous tissue extends from the apex toward and often involves the HEART VALVES causing restrictive blood flow into the respective ventricles (CARDIOMYOPATHY, RESTRICTIVE).
- 425.0 is a specific code that can be used to specify a diagnosis
- 425.0 contains 4 index entries
Hypertrophic obstructive cardiomyopathy- A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
- 425.1 is a specific code that can be used to specify a diagnosis
- 425.1 contains 8 index entries
Obscure cardiomyopathy of africa- A condition characterized by the thickening of the ventricular ENDOCARDIUM and subendocardium (MYOCARDIUM), seen mostly in children and young adults in the TROPICAL CLIMATE. The fibrous tissue extends from the apex toward and often involves the HEART VALVES causing restrictive blood flow into the respective ventricles (CARDIOMYOPATHY, RESTRICTIVE).
- 425.2 is a specific code that can be used to specify a diagnosis
- 425.2 contains 8 index entries
Endocardial fibroelastosis- A condition characterized by the thickening of ENDOCARDIUM due to proliferation of fibrous and elastic tissue, usually in the left ventricle leading to impaired cardiac function (CARDIOMYOPATHY, RESTRICTIVE). It is most commonly seen in young children and rarely in adults. It is often associated with congenital heart anomalies (HEART DEFECTS,CONGENITAL); INFECTION; or gene mutation. Defects in the tafazzin protein, encoded by TAZ gene, result in a form of autosomal dominant familial endocardial fibroelastosis.
- 425.3 is a specific code that can be used to specify a diagnosis
- 425.3 contains 9 index entries
Other primary cardiomyopathies- A form of CARDIAC MUSCLE disease in which the ventricular walls are excessively rigid, impeding ventricular filling. It is marked by reduced diastolic volume of either or both ventricles but normal or nearly normal systolic function. It may be idiopathic or associated with other diseases (ENDOMYOCARDIAL FIBROSIS or AMYLOIDOSIS) causing interstitial fibrosis.
- A form of CARDIAC MUSCLE disease that is characterized by ventricular dilation, contractile dysfunction of the left or both HEART VENTRICLES, and congestive heart failure (HEART FAILURE, CONGESTIVE) symptoms. Risk factors include ETHANOL and TOBACCO abuse, PREGNANCY; HYPERTENSION; INFECTION; and mutations in the LMNA gene encoding LAMIN TYPE A, a NUCLEAR LAMINA protein.
- A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
- A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
- 425.4 is a specific code that can be used to specify a diagnosis
- 425.4 contains 14 index entries
Alcoholic cardiomyopathy- Disease of CARDIAC MUSCLE resulted from chronic excessive alcohol consumption. Myocardial damage can be caused by: (1) a toxic effect of alcohol; (2) malnutrition in alcoholics such as THIAMINE DEFICIENCY; or (3) toxic effect of additives in alcoholic beverages such as COBALT. This disease is usually manifested by DYSPNEA and palpitations with CARDIOMEGALY and congestive heart failure (HEART FAILURE, CONGESTIVE).
- 425.5 is a specific code that can be used to specify a diagnosis
- 425.5 contains 7 index entries
Nutritional and metabolic cardiomyopathy- 425.7 is a specific code that can be used to specify a diagnosis
- 425.7 contains 51 index entries
Cardiomyopathy in other diseases classified elsewhere- 425.8 is a specific code that can be used to specify a diagnosis
- 425.8 contains 19 index entries
Secondary cardiomyopathy unspecified- 425.9 is a specific code that can be used to specify a diagnosis
- 425.9 contains 4 index entries
