The incidence of coronary heart disease is lower in women compared to male patients. Among myocardial infarction patients, the male:female ratio is about 2.7:1, but the annual mortality rate of coronary heart disease in women gradually increases with age. Generally speaking, women have thinner coronary arteries than men, and their serum cholesterol is generally lower than that of men, but women are more likely to have increased lipids after the age of 60; after menopause, women have a tendency to develop hypertension and diabetes than men. Compared with male patients, women have a greater than 75% mortality rate in the first month after a myocardial infarction, and the annual mortality rate and risk of reinfarction are more than one times that of men. Women with myocardial infarction also have a poorer long-term prognosis, and the mortality rate of myocardial infarction in women was found to be approximately 50% when the group of patients older than 60 years was followed for 12 years.
