There is no clear information on the 5-year survival rate of patients with coronary heart disease, which generally does not affect life expectancy. It is lower if the patient suffers from severe coronary heart disease and may even lead to sudden death. The 5-year survival rate of patients with coronary heart disease is related to the severity of the disease, the patient’s physical condition, the degree of recovery and other factors. Patients who have had a myocardial infarction or have angina symptoms and take their medication on time and as prescribed by the doctor will generally not affect their life expectancy. If the patient suffers from severe coronary artery disease, has had a large myocardial infarction, and has been repeatedly hospitalized for heart failure, the 5-year survival rate is lower and there may be a risk of sudden death. With active treatment, patients with coronary artery disease will have a good life expectancy, and the impact on life expectancy is generally not significant. If treatment is not cooperated and coronary heart disease develops into heart failure, the mortality rate is very high. If you are diagnosed with coronary heart disease, you should follow the doctor’s instructions to adhere to long-term medication, carry out planned and appropriate exercise, and go to the hospital regularly for follow-up.
