A few days ago, the actor GaoXiuMin and due to myocardial infarction suddenly died, regrettable, which gives people concerned about health has brought a lot of warning and thinking. In the past, people habitually think that coronary heart disease is a disease of the elderly, but in recent years, the incidence of coronary heart disease has a “rejuvenation” trend, the current data show that acute myocardial infarction patients less than 60 years of age more than half of the patients, 20% of the patients less than 50 years of age, a small number of patients only 20-30 years of age, and the onset of young people myocardial infarction 10 percent of the people The onset of myocardial infarction in 10% of young people is characterized by sudden death. The basic lesion of coronary heart disease is atherosclerosis of coronary arteries, which are the blood vessels supplying myocardial nutrients. Coronary arteries can have lipid lines in adolescence, and then gradually develop in the following decades to form atherosclerotic plaques, and in recent years, with the aggravation of social competition, changes in dietary structure, and other factors, the process is accelerated, with a younger incidence. Therefore, it is not difficult to understand that the prevention of coronary heart disease in young and middle-aged people should pay particular attention. The first step in preventing coronary heart disease is to assess whether one belongs to the “high-risk group” for coronary heart disease, i.e., to evaluate whether one has the risk factors for coronary heart disease. Recognized risk factors include being male, diabetes mellitus, hypertension, dyslipidemia, cigarette smoking, a family history of early onset of coronary heart disease, excessive obesity, and a clear past history of cerebrovascular or peripheral vascular obstruction. The more risk factors you have, the greater the probability of suffering from coronary heart disease in the future, the more attention should be paid, in addition to active prevention, but also need to pay attention to whether or not you have suffered from coronary heart disease, to achieve “early detection, early treatment”, the typical symptoms of coronary heart disease is related to the activities of the sternum after the feeling of pressure, feeling of stuffiness, but there are also many atypical manifestations, the need for Keeping in mind that “if you have chest tightness and pain, go to the hospital”, even if the person is asymptomatic, but also can not be excluded from the coronary heart disease, there are high-risk factors should be regularly go to the cardiovascular specialist evaluation, in order to early detection of coronary heart disease, and at the same time can also be guided by a doctor, the application of such as aspirin, etc. can prevent the occurrence of cardiovascular events of the medication and medication to intervene in the risk factors. It is essential for young and middle-aged people to go to the hospital for regular medical checkups, such as annual checkups, to evaluate blood pressure, blood glucose, and blood lipid levels, in order to detect risk factors early and intervene at an early stage. All risk factors can be intervened except gender and family history, which cannot be changed. Those with hypertension should control their blood pressure below 140/90mmHg through lifestyle changes in conjunction with medication. Dyslipidemia refers to elevated total cholesterol, LDL cholesterol, and triglycerides, as well as lowered HDL cholesterol. Either abnormality is accompanied by increased morbidity and mortality from coronary heart disease, and in addition to lifestyle changes, pharmacological interventions should be decided under the guidance of a physician, depending on the number of risk factors. Male smokers have a 1.6-fold increase in total mortality, cardiovascular morbidity and mortality compared to non-smokers. The relative risk of fatal and non-fatal heart attacks is 2.3 times higher in smokers than in non-smokers. Quitting smoking for one year halves the excess risk of coronary heart disease compared with continuing smokers. Therefore, it is never too late to quit smoking. If you are a heavy smoker, you can make the transition through nicotine replacement therapy using nicotine tablets and nicotine gum. There is now a saying that having diabetes is equivalent to having had a heart attack. This statement is not excessive, because a study found that diabetic patients who have not had a heart attack with no diabetes heart attack patients have the same risk of death, diabetic patients often have a variety of coronary heart disease risk factors, in the coronary heart disease in a high degree of threat, in addition to active control of blood glucose, medication to maintain an ideal level of blood pressure, blood lipids, and also regular coronary heart disease related checkups. Maintaining a healthy lifestyle is important both for the prevention of coronary heart disease and for the prevention and treatment of coronary heart disease risk factors such as diabetes mellitus, hypertension and dyslipidemia. Hyperlipidemia, diabetes mellitus and obesity are all related to dietary nutrition. Reasonable dietary structure is very important for the prevention of coronary heart disease, and overweight can be corrected through the control of total calories eaten every day. Fat intake should be limited to vegetable fats, and it is recommended to eat foods containing unsaturated fatty acids such as marine fish and to eat less cream, egg yolks, fatty pork, fatty mutton, fatty beef, liver, viscera, and meat and oil. Diet should be light, low salt, salt intake is controlled at less than 5 grams per day, which is especially important for people with hypertension. Promote eating more fresh vegetables and fruits to supply sufficient vitamins, inorganic salts, trace elements and dietary fiber. Drinking a lot of alcohol can cause elevated blood lipids, and can induce angina pectoris, while a small amount of low alcohol can have a cardioprotective effect, generally can drink low alcohol to 1 day no more than 50 grams is appropriate. Life lies in exercise. Regular exercise, can reduce blood lipids, reduce the incidence of coronary heart disease, aerobic exercise such as jogging, swimming, walking, cycling, etc. more beneficial, scientific and reasonable practice is to start from a small amount of exercise, follow the principle of slow and gentle, gradually increase the amount of exercise, exercise intensity should not be too large, the highest heart rate of 110 to 120 beats per minute during exercise and does not cause discomfort appropriate. Exercise frequency can generally be 3 to 5 times a week, each time about 30 minutes. People in middle age, all aspects of the pressure is great, to avoid overload. Long-term mental tension and emotional factors, such as anxiety, depression, emotional excitement is often the trigger of coronary heart disease. Should learn to regulate the rhythm of life, tension and relaxation, control bad mood. If you start prevention at the age of 40, you can reduce the incidence of coronary heart disease by 50%; at the age of 50, you can reduce the incidence of less than 40%, if you start prevention at the age of 70, you can only reduce the incidence of less than 20%. Therefore, in order to have a healthy heart, we must pay attention to the prevention of coronary heart disease from the middle age.
