What medication to take for heart disease depends on what kind of heart disease and the functional state of the heart. Classified by etiology, common heart diseases currently include coronary heart disease, hypertensive heart disease, rheumatic heart disease, and infectious heart disease. There are many kinds of medications available to treat heart disease, and the exact type of medication to take depends on the symptoms and condition. The following are the commonly used drugs for coronary heart disease and hypertensive heart disease, including anti-anginal drugs, anti-platelet drugs, blood pressure lowering drugs, lipid lowering drugs, etc. 1, coronary heart disease: coronary heart disease requires anti-angina drugs, anti-platelet drugs, lipid-lowering drugs, etc. (1) anti-angina drugs: used for the treatment or prevention of angina, mainly including nitrate drugs, beta-blockers and calcium channel antagonists. Nitrate drugs include nitroglycerin (fast-acting) and isosorbide nitrate (medium and long-acting). beta-blockers include metoprolol and bisoprolol, which can reduce myocardial oxygen consumption and have anti-arrhythmic effects. Calcium channel antagonists include nifedipine, diltiazem, verapamil, etc., which can relieve angina and lower blood pressure. However, these drugs have specific contraindications and side effects, and must be taken under the guidance of a doctor. (2) Anti-platelet drugs: including aspirin, clopidogrel, prasugrel, and tegretol, can inhibit the formation of blood clots in blood vessels, thus reducing the risk of heart attack and stroke. Antiplatelet drugs are often required for patients with coronary artery disease and post-stenting. When taking antiplatelet agents, care should be taken not to stop taking them without authorization and to seek medical attention in case of serious bleeding. (3) Hyperlipidemic drugs: Statins are the most commonly used lipid-regulating drugs, including atorvastatin, pravastatin, lovastatin, simvastatin and so on. They not only reduce lipid levels but also stabilize plaque and reduce the risk of heart attack and stroke, which is important in the treatment of coronary heart disease. Other lipid-regulating drugs include niacin, fibrates, cholesterol absorption inhibitors, fish oil preparations, etc., which should be taken under the guidance of a doctor. 2, hypertensive heart disease: hypertensive heart disease is caused by hypertension, commonly used diuretics, calcium antagonists, angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor antagonists (ARB), beta-blockers and other five types of drugs. Diuretics have a good antihypertensive effect, are affordable and can significantly reduce the incidence of cardiovascular events and overall mortality, and are commonly used clinically as thiazide diuretics (hydrochlorothiazide, etc.). Calcium antagonists have a significant antihypertensive effect, and can be used in combination with other antihypertensive drugs to further enhance antihypertensive efficacy, with relatively few side effects, significant impact on blood glucose, lipid metabolites, and better long-term blood pressure control ability, mainly including amlodipine, nifedipine, verapamil, diltiazem, etc. ACEI drugs mainly include captopril, enalapril, benazepril, perindopril, midazepril, etc., which can dilate blood vessels, reduce blood pressure, reduce cardiac load and improve cardiac function, and prolong survival time after heart attack. ARB drugs act similarly to ACEI, and can be used as an alternative to ACEI drugs for patients who experience severe cough and other side effects after taking ACEI. They mainly include coxsartan and telmisartan. Beta-blockers can reduce heart rate, lower blood pressure, and reduce the risk of heart attack. Some patients with arrhythmia and angina need to take beta-blockers, mainly including metoprolol, bisoprolol, etc. Rheumatic heart disease and infectious heart disease (such as viral myocarditis and tuberculous pericarditis) need to be treated for specific etiologies in addition to cardiac function. The acute phase of rheumatic heart disease should be treated with anti-rheumatic therapy, viral heart disease should be treated with anti-viral therapy, and tuberculous pericarditis should be treated with anti-tuberculous therapy. Primary cardiomyopathy should be treated with individualized treatment options for myocardial lesions and abnormal cardiac function. There is a wide variety of heart disease medications and patients often need to take multiple medications at the same time. Cardiac medications must be taken under the guidance of a physician, and patients should not purchase and take them on their own. Patients should pay close attention to the symptoms of discomfort while taking the medication and make regular follow-up visits to adjust the medication.
