The incidence of coronary heart disease begins to rise after the age of 40, and is lower in women than in men before menopause and equal to that of men after menopause. The incidence of coronary heart disease increases with age, and the degree of coronary heart disease also increases with age. Some data show that the prevalence of coronary heart disease increases 1 times for every 10 years since the age of 40. Coronary atherosclerosis develops more rapidly after the age of 50 for men and 60 for women, and the risk of myocardial infarction also increases with age. Atherosclerosis gradually comes out from early childhood, only that the degree and speed of its lesions increase with age, so the prevention of coronary heart disease should start at an early age. With the growth of age, various organs and tissues of the human body will gradually appear aging, and blood vessels will also harden, on this basis, it is easy to induce coronary heart disease. Of course, in recent years, it is found that there is a trend of increasing the number of young patients with coronary heart disease year by year, which is mainly related to poor diet and living habits.
