What are the common diseases of the heart?

Cardiology commonly deals with a wide variety of diseases, primarily including coronary artery disease, hypertension, arrhythmia, myocarditis, cardiomyopathy (such as hypertrophic cardiomyopathy, dilated cardiomyopathy), heart failure, valvular heart disease, rheumatic heart disease, congenital heart disease (such as atrial septal defect, ventricular septal defect), myocardial infarction, angina pectoris, infective endocarditis, hyperlipidemia, and cardiac neurosis. Most of these diseases are associated with multiple factors such as aging, genetics, lifestyle, and environmental influences, and often require timely diagnosis and treatment to prevent disease progression and life-threatening complications. In daily life, maintaining a healthy lifestyle and undergoing regular medical check-ups are of great importance in the prevention of cardiovascular diseases.
