Survival of myocardial infarction patients after conservative treatment varies from person to person, and in general, patients have a high 5-year mortality rate. The prognosis of patients with myocardial infarction is closely related to the size of the infarction, whether revascularization is taken in time, and whether standardized medical treatment is actively carried out. If myocardial infarction is followed by early and effective intervention to open the blood vessels and there is no serious structural damage to the heart, the patient can achieve long-term survival. If the infarction is large, patients may survive after conservative treatment. Once it develops into heart failure, with manifestations such as chest tightness and shortness of breath and cardiac insufficiency, the patient’s 5-year survival rate is the same as that of the tumor, which may only be about 30-40%. Therefore, acute myocardial infarction with conditions, it is recommended to timely vascularization treatment, is not recommended to choose conservative treatment, otherwise it will affect the quality of life and survival period, or affect life expectancy. In addition, patients are advised to take care of less greasy food and avoid eating high-fat food as well as poultry meat and animal offal.
