The treatment of angina is to choose a beta-blocker that slows the heart rate, weakens myocardial contractility, and lowers blood pressure, such as betalactam, which reduces angina attacks and increases exercise tolerance; and a nitrate agent, which reduces myocardial oxygen demand and improves myocardial perfusion, such as nitroglycerin. There is also a calcium channel blocker, which helps to inhibit myocardial contractility and reduce myocardial oxygen consumption, commonly used is verapamil; to prevent heart attack and improve prognosis, you can also use aspirin to anti-platelet aggregation. In the care, we should pay attention to the diet, choose low-calorie, low-fat, low-cholesterol, easy-to-digest food, in order to prevent the appearance of constipation, choose high-fiber vegetables and fruits, and abstain from smoking, alcohol and spicy food, and relieve the patient’s nervousness and anxiety.
