Risk factors for coronary heart disease include: (1) Age: The prevalence of coronary heart disease is higher in people over 40 years of age, and the prevalence increases approximately 1-fold with each 10-year increase in age. (2) Gender: The prevalence of coronary heart disease is higher in men than in women, but the prevalence of coronary heart disease in women after menopause is comparable to that in men. (3) Dyslipidemia: A long-term high-fat diet can cause an increase in blood cholesterol and triglycerides, leading to atherosclerosis. (4) Smoking: nicotine in tobacco, which can increase myocardial stress, increase cholestrol and platelet adhesion and aggregation. (5) Lack of physical activity: those with less physical activity have 2.5-4 times higher prevalence, and exercise can burn excess calories and prevent their conversion into fat. (6) hypertension: increased blood pressure increases the pressure on the blood vessel wall, making it easy for cholesterol to enter the arterial wall and promote thrombosis, leading to intimal fibroplasia and atherosclerosis. (7) obesity: obese and overweight people are prone to hypertension, insulin resistance and diabetes, and their lipid profile can also appear significantly abnormal, and also increase the burden on the heart. (8) Diabetes mellitus: diabetes mellitus itself can lead to macrovascular and microvascular complications and promote atherosclerosis, and its 10-year risk of myocardial infarction is the same as that of patients with coronary heart disease. (9) Family history: Patients with positive family history have significantly higher prevalence of coronary heart disease in their offspring and their risk is also significantly increased. (10) Long-term mental laborers: their mental tension, sympathetic nervous system in a long-term state of excitement, increased secretion of catecholamines, resulting in the prevalence of coronary heart disease is 1 times higher than that of manual laborers.
