Definition and classification of cardiomyopathy

According to the definition of cardiomyopathy, it can be divided into five types: dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, arrhythmic right ventricular cardiomyopathy and unclassified cardiomyopathy. The symptoms, causes and treatment methods vary according to the disease. According to the definition of cardiomyopathy, it can be divided into the following types: 1. Dilated cardiomyopathy: characterized by ventricular chamber enlargement and myocardial systolic dysfunction. Common symptoms include dyspnea, fatigue, edema, etc. The cause may be related to genetic, infection, poisoning and other factors. Treatment methods include drug therapy, cardiac resynchronization therapy, heart transplantation, etc. 2. Hypertrophic cardiomyopathy: Cardiac hypertrophy is the main feature. Common symptoms include dyspnea, chest pain, palpitations, etc. The cause may be related to gene mutation. Treatment methods include drug therapy, surgical treatment, etc. 3. Restrictive cardiomyopathy: ventricular filling limitation as the main feature. Common symptoms include dyspnea, fatigue, edema, etc. The cause may be related to myocardial fibrosis, amyloidosis and other factors. Treatment methods include drug therapy, heart transplantation, etc. 4. Arrhythmogenic right ventricular cardiomyopathy: It is characterized by progressive replacement of the right ventricular myocardium by fibrous adipose tissue. Common symptoms include arrhythmia, syncope, heart failure, etc. The cause may be related to gene mutation. Treatment methods include drug therapy, cardiac resynchronization therapy, implantable cardioverter defibrillator, etc. 5. Unclassified cardiomyopathy: Cardiomyopathy of unknown etiology or caused by a combination of factors. Common symptoms include heart failure, arrhythmia, etc. Treatment depends on the individual condition. It should be noted that the diagnosis of cardiomyopathy needs to be combined with clinical manifestations, ECG, echocardiography, etc., and exclude other diseases that may cause similar symptoms. Treatment should be based on the type of cardiomyopathy, severity of the disease, and individual conditions of the patient. At the same time, patients should follow the doctor's advice for treatment, including medication, lifestyle changes

(such as smoking cessation, alcohol restriction, weight control, appropriate exercise, etc.), regular follow-up, etc. For patients with cardiomyopathy, early diagnosis and treatment can improve symptoms, improve quality of life, and reduce mortality.
