Coronary heart disease patients are suitable to eat low-salt, low-fat and low-calorie food, and suitable to take aspirin, clopidogrel and other drugs. 1. Since hypertension, hyperglycemia, hyperlipidemia and the onset and prognosis of coronary heart disease are related, coronary heart disease patients are suitable to eat low-salt, low-fat and low-calorie foods, such as vegetables, fruits, cereals, beans, seafood and so on. Prohibit spicy, greasy stimulating food, strict abstinence from smoking and alcohol. 2. Aspirin and clopidogrel have the effect of inhibiting platelet aggregation, which can reduce coronary thrombosis; drugs such as atorvastatin and resuvastatin can reduce the synthesis of hepatic cholesterol, thus inhibiting the process of coronary atherosclerotic lesions; drugs such as metoprolol and sotalol can slow down the heart rate and reduce myocardial oxygen consumption. Pay attention to the use of drugs under the guidance of a physician.
