Conservative treatment of heart attack is effective, there is no myocardial ischemia, angina attack, generally does not affect the patient’s life expectancy, the prognosis is good. Coronary heart disease is coronary atherosclerotic heart disease, coronary artery lining due to lipid deposition to form plaques, blockage of blood vessels, causing blockage of blood flow to the distal end of the blood vessel to reduce or interrupt, resulting in ischemia or necrosis of myocardial cells, clinical manifestations of angina pectoris or myocardial infarction. Conservative treatment of myocardial infarction patients mainly refers to drug therapy, through the expansion of coronary, anticoagulation, lipid regulation, plaque stabilization and other comprehensive treatment, can make myocardial ischemia symptoms significantly improved, no angina attack, actively cooperate with the doctor’s guidance, follow the doctor’s instructions to take the medication on time, to maintain a good habit of life, emotional stability, ban smoking, limit alcohol, light diet, do not overeat, and adhere to aerobic exercise, regular clinic follow up, timely adjustments Use medication and strengthen the implementation of secondary prevention measures for coronary heart disease outside the hospital.
