More than 50% of heart disease is due to bad mood, so I want to emphasize good mood! The following are the risk factors of heart disease, just pay attention! (1) Age: This disease is more common in middle-aged and elderly people over 40 years old, and it progresses rapidly after 49 years old. The incidence of myocardial infarction and sudden death in coronary heart disease is proportional to age. In recent years, the onset of coronary heart disease tends to be younger, and the onset time of women is usually about 10 years later than that of men. (2) Gender: There are indeed gender differences in the occurrence, development and prognosis of some diseases. There are many differences between men and women as far as coronary heart disease is concerned. Generally speaking, compared with men, the onset time of coronary heart disease in women is later, about 10 years later. Before the age of 55, even if women have coronary heart disease, they rarely have myocardial infarction and sudden death. The main symptoms are angina pectoris, the condition is lighter than that of men, the prognosis is better and the survival rate is higher. In the United States, the mortality rate of male coronary heart disease is significantly higher than that of female. According to the statistical data of 1979, the mortality rate of coronary heart disease in white men aged 35-44 is 5.2 times that of women. In China, the ratio of male to female is about 2:1. However, after menopause, the incidence of coronary heart disease in women increased significantly due to the obvious decrease of estrogen level and the increase of low density lipoprotein. Some data show that the incidence of coronary heart disease in women after 60 years old is greater than or equal to that in men. (3) Inactivity and decreased exercise: A large number of epidemiological studies in the United States in recent years 10 have drawn the following conclusions: moderate exercise can reduce the risk of coronary heart disease, and the risk of coronary heart disease in inactive people will increase by 2 times, which is similar to the increase of systolic blood pressure, smoking and serum cholesterol. The incidence of this disease is higher among mental workers than manual workers, and people who often have a sense of urgency and psychological pressure and can't afford to buy things are prone to this disease. (4) Diet and obesity: People who often eat a high-calorie diet and have more animal fat and cholesterol are prone to this disease. At the same time, eating too much is also easy to get this disease. Researchers in Germany, the world's first obese country, believe that "eating fat is because there is no way out", so to control the incidence of coronary heart disease, we should pay attention to controlling food intake in addition to controlling the intake of high-fat diet. In recent years, the relationship between obesity and coronary heart disease has been paid more and more attention. Obesity is one of the risk factors of coronary heart disease. Overweight obese people (10% is mild, 20% is moderate, and 30% is severely obese) are prone to this disease, especially those who gain weight quickly. And we should not only look at the body mass index, but also measure the thickness of subcutaneous fat. Moreover, centripetal obesity is very dangerous. (5) Mental stress: Mental stress can induce coronary heart disease. A study of 830 14 employees in a Finnish company found that the relative risk of coronary heart disease of employees with high stress is 1.58 times that of ordinary people, and that of employees with low stress is 1. 16 times, which increases the risk by 50%. The descendants of 3682 patients with coronary heart disease were followed up for 10 years in the United States. The results showed that the risk of coronary heart disease was 1.25 times that of ordinary people, and the risk of death was 1.23 times that of ordinary people, which was more than 20% higher than that of people with low or no stress. It will also aggravate the degree of vascular stenosis. Eighty patients with coronary heart disease were studied in the United States and Sweden for three years, and coronary angiography was performed at the beginning and end of the observation. The results showed that the degree of cardiac vascular stenosis in patients with high pressure increased by 7.65438 0%, while that in patients without pressure decreased by 5.2%. Stress and mental factors can promote the onset of acute coronary syndrome. An Israeli study of 209 patients with acute coronary syndrome found that the relative risk of heart attack caused by bad mood was 14 times higher than normal, so stress can promote the instability of atherosclerotic plaques. A study of 2 1 patient with coronary heart disease in the United States found that although there was no change in chest pain and electrocardiogram in hypertensive patients, myocardial perfusion imaging showed that 6 patients had reversible myocardial ischemia and 85% patients had endothelial dysfunction. (6) Blood pressure and blood lipids: First, elevated blood pressure is an independent risk factor for coronary heart disease. Coronary artery and cerebral artery are the most common hazards of atherosclerosis caused by hypertension. 60% ~ 70% patients with coronary atherosclerosis have high blood pressure, which is four times that of normal people. According to the latest national standards, the hypertension standards of systolic blood pressure 160mmHg and diastolic blood pressure 95mmHg were changed to systolic blood pressure 140mmHg and diastolic blood pressure 90mmHg. Hypertension is an important risk factor of coronary heart disease, which has been widely and consistently confirmed by epidemiology, clinic, pathology and laboratory observation. According to a recent research report, if the average systolic blood pressure increases by 2mmHg, the incidence of coronary heart disease will increase by 6/65438+ million. Second, blood lipids, abnormal blood lipids caused by genetic factors or excessive fat intake, or disorder of lipid metabolism. Blood lipids include cholesterol, cholesterol esters, triglycerides, phospholipids and free fatty acids. When combined with some globulins, they become water-soluble lipoproteins, including chylomicrons (CM), very low density lipoproteins (VLDL), low density lipoproteins (LDL) and high density lipoproteins (LDL). At present, it is considered that when serum cholesterol (TC) increases (> 200 mg/dl), low density lipoprotein (LDL-c) increases (> 55 mg/dl) and high density lipoprotein (HDL-c) decreases (< 4.5), the risk of coronary heart disease increases obviously, and the greater the above ratio, the greater the risk. For every 5 mg/dl increase in serum cholesterol, the incidence of coronary heart disease increased by 5/65438+ ten thousand. (7) Smoking: Smoking is the main risk factor of coronary heart disease. Compared with non-smokers, the incidence and mortality of the disease increased by 2 ~ 6 times, and it was directly proportional to the number of smokers every day. Epidemiological studies at home and abroad believe that smoking is an important risk factor for coronary heart disease, myocardial infarction and sudden death, especially for people with other risk factors of coronary heart disease.
