Judging from the incidence of coronary heart disease, coronary heart disease will affect life expectancy, because coronary heart disease is one of the main causes of death at present. In recent years, the incidence of coronary heart disease is getting higher and higher, and the mortality is getting higher and higher. But generally speaking, coronary heart disease has little effect on life expectancy. Although this disease can't be cured well, as long as it is well controlled, patients rarely get sick. As long as some complications are avoided, it will not endanger life. As long as the treatment is proper, the patient has the possibility of long-term survival.
