Cardiomyopathy
Urgent
Cardiomyopathy refers to diseases of the heart muscle that can make the heart enlarged, thickened, stiff, or weakened and impair its ability to pump blood normally. Different types include dilated, hypertrophic, restrictive, and arrhythmogenic cardiomyopathies. Complications may include heart failure and abnormal heart rhythms.

Overview
Cardiomyopathy refers to diseases of the heart muscle that can make the heart enlarged, thickened, stiff, or weakened and impair its ability to pump blood normally. Different types include dilated, hypertrophic, restrictive, and arrhythmogenic cardiomyopathies. Complications may include heart failure and abnormal heart rhythms.
Symptoms 3
Burning Urination
Chest Pain
High Blood Pressure
Causes 3
Causes vary according to the type of cardiomyopathy. Genetic changes can cause some forms, particularly hypertrophic and certain inherited cardiomyopathies. Other causes include coronary artery disease, previous heart attack, high blood pressure, infections, inflammation, metabolic disorders, alcohol or toxic exposures, and some medicines. In some people, no specific cause is identified.
Alcohol
Genetics
Infection
Risk Factors
Risk depends on the type and cause. Family history of cardiomyopathy or unexplained sudden cardiac death can increase risk. Other factors may include coronary artery disease, high blood pressure, previous heart attack, certain infections or inflammatory diseases, heavy alcohol use, and conditions or medicines that damage the heart muscle.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis may include medical and family history, physical examination, ECG, echocardiography, chest imaging, blood tests, and sometimes cardiac MRI. Additional testing may include exercise testing, heart rhythm monitoring, genetic testing, or cardiac catheterization depending on the suspected type and severity.
Prevention
Key Prevention Tips
Some forms of cardiomyopathy cannot be prevented, particularly inherited forms
Managing blood pressure, coronary artery disease, diabetes, and other conditions that affect the heart can reduce risk of acquired disease
Avoiding excessive alcohol and harmful substances, following prescribed treatment, and evaluating unexplained heart symptoms or a strong family history can help reduce complications
Prevention Guidance
Some forms of cardiomyopathy cannot be prevented, particularly inherited forms. Managing blood pressure, coronary artery disease, diabetes, and other conditions that affect the heart can reduce risk of acquired disease. Avoiding excessive alcohol and harmful substances, following prescribed treatment, and evaluating unexplained heart symptoms or a strong family history can help reduce complications.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
