Heart disease is a collective term for a series of diseases caused by structural or functional disorders of the cardiovascular system, of which coronary heart disease is the most common. Patients with coronary artery disease should take medications to reduce the risk of myocardial infarction and improve their prognosis, such as aspirin, atorvastatin and metoprolol. In severe cases, hemodialysis is required. Patients with coronary artery disease should quit smoking, limit alcohol, control sugar, lower blood pressure, improve lifestyle while using antiplatelet drugs aspirin to stabilize plaque, nitrate drugs to improve myocardial ischemia, statins atorvastatin to lower lipids and stabilize plaque, and rationally use ACEI/ARB and β-blockers such as metoprolol to improve the patient’s prognosis and other treatments. If there is no significant improvement in symptoms, coronary angiography can be performed to assess the degree of coronary artery stenosis, and for patients who meet the indications for surgery, it is recommended to perform revascularization therapy, such as percutaneous coronary artery stenting or coronary artery bypass grafting. Heart disease also includes heart failure, arrhythmia, valvular disease, cardiomyopathy, myocarditis, pericarditis, hypertension and so on. It is necessary to choose the appropriate medication according to the patient’s condition, and the specific treatment plan should be carried out under the guidance of the doctor.
