Coronary heart disease patients at the age of 50 with good cardiac function, mild coronary artery disease and small myocardial involvement, and fewer co-morbidities and cooperation with treatment usually do not affect normal life expectancy; on the contrary, the prognosis is poorer. Coronary heart disease prognosis varies from person to person, generally speaking, if the patient’s coronary artery stenosis degree is light and the affected myocardial area is small, at the same time have better heart function, hypertension, diabetes and other comorbidities are less, often has a more ideal prognosis, usually can live for more than ten years or even decades. In addition, for patients who have a high degree of adherence to a diet that avoids grease and high salt, stops smoking and drinking, maintains appropriate exercise, and takes medications as prescribed, the prognosis can often be further improved. If the patient has more underlying diseases, poorer physical and cardiac function, and ischemic cardiomyopathy, the prognosis is often poor, and the life expectancy is relatively short. Patients are advised not to be overly nervous and to actively cooperate with the diagnosis and treatment.
