First, we must pay attention to diet and exercise properly. The low-salt and low-fat diet must limit the intake of salt and fat, and eat more brown rice, vegetables and fruits, which can obviously reduce the occurrence of myocardial infarction. You also need to do proper exercise, choose a reasonable exercise mode according to your physical condition, and lose weight, which can obviously reduce myocardial infarction.

Second, life should be regular, you must not stay up late often, you should combine work and rest to ensure adequate sleep, and it is best to go to bed early and get up late.

Third, patients who smoke and drink must give up smoking and alcohol, because smoking and drinking will cause coronary artery spasm and induce myocardial infarction.

Fourth, we should add and subtract clothes in time according to the weather changes, because the weather is getting colder and colder. If we don't keep warm in time, blood vessels will contract, leading to myocardial infarction.

Fifth, for some elderly people, especially those with constipation, it is necessary to keep their stools unobstructed and avoid myocardial infarction if they have difficulty defecating.

Sixth, for patients with hypertension, hyperlipidemia and hyperglycemia, we must strictly control blood pressure, blood sugar and blood lipids to avoid myocardial infarction and reduce blood lipids to a minimum. Blood pressure and blood sugar must be within the standard range.

Seventh, if you already have coronary heart disease, you must take medicine regularly and check it regularly. You must insist on taking aspirin, statins and nitrates, as well as auxiliary drugs such as Danshen dripping pills, Ginkgo biloba leaves or Xuesaitong tablets to reduce the incidence of myocardial infarction.
