The full name of heart attack is myocardial infarction, which refers to ischemic necrosis due to insufficient blood supply to the myocardium caused by factors such as blockage of coronary arteries. The methods of preventing heart attack include controlling high-risk factors, adopting a good lifestyle and standardized drug treatment. 1. Control risk factors: heart attack usually occurs when patients have underlying diseases, such as high blood pressure, high blood sugar, high blood lipids, etc. Such chronic diseases easily lead to cardiovascular disease. Such chronic diseases easily lead to cardiovascular hardening and damage, so we need to go to the hospital in time for treatment, control it not to deteriorate, such as taking blood pressure, lipid-lowering drugs, statin drugs, etc., to prevent the emergence of heart attack. 2. Adopt a good lifestyle: heart attack is usually related to high oil and high salt diet, so we need to advocate a light diet in daily life, quit smoking and limit oil, and at the same time, actively exercise to improve cardiovascular function, increase the elasticity of blood vessels, reduce blood viscosity, and develop a good habit of life. 3. Standardized drug therapy: the causes of heart attack usually include coronary artery stenosis and platelet aggregation. At this time, it is necessary to preventive use of antiplatelet drugs, such as aspirin, or take nitrate and calcium channel blockers such as nifedipine, etc., to improve the symptoms of myocardial ischemia, in order to prevent the emergence of heart attack. In summary, the prevention of heart attack needs to synthesize the situation of many parties, if the prevention is insufficient, after the emergence of heart attack, you need to call for help in time, and quickly go to the hospital to prevent cardiac arrest, resulting in the death of the patient.
