Cardiovascular diseases are the number one killer of human life and health, and coronary heart disease is one of the culprits. The pathological process of coronary atherosclerosis is a fairly long one, and its pathogenesis can begin at an early age. Almost all people develop some procedure of atherosclerosis, it’s just that someone has not developed it enough to show clinical symptoms. That is, that side of the process of atherosclerosis formation and the body’s resistance to atherosclerosis dominates, making the symptoms of atherosclerosis gradually manifest as we age. Therefore, we should not start to pay attention to the symptoms of coronary heart disease only when they appear, and the prevention of coronary heart disease should start from adolescence in order to really reduce the incidence of coronary heart disease. Large-scale international studies have shown that more than 90% of serious cardiovascular events can be predicted by known risk factors: smoking, dyslipidemia, hypertension, diabetes, obesity, stress, unhealthy diet and lack of physical exercise. The whole society should pay attention to the prevention of heart disease, and the focus should be on the following aspects. 1, active prevention of obesity Adults are difficult to lose weight, in order to prevent obesity should start from childhood. Children are in the growth and development period, supply enough protein, fiber and the required calories is undoubtedly, but need to avoid too much fat and sweets, and encourage children to do more outdoor activities to ensure the normal growth and development of children, to avoid the emergence of too many obese children. For adult obese people should also actively improve living habits and reduce weight. 2, prevention of hypertension To regular blood pressure measurement, blood pressure value in the upper percentile should be given life guidance, limit the intake of salt, salt control within 6 grams per day, and at the same time should pay attention to increase the content of calcium in the diet. Dietary free calcium per kilocalorie can increase 100 mg, the systolic blood pressure can be reduced by 0.266kPa (2.0mmHg). 3, quit smoking smoking will have a great promotion of the formation of atherosclerosis, from the beginning to strictly control the formation of this bad habit of smoking, already smoking should quit smoking as soon as possible. 4, eat a lot of fruits and vegetables, but the diet should be maintained in a balanced and even. 5, often exercise Evidence shows that doing two or three times a week strenuous exercise, can reduce the risk of heart disease. But because it is dangerous to do strenuous exercise suddenly, you must start your exercise program in a gradual manner. 6, to cope with mental stress Seek various ways to mediate the stress of life. You can cultivate hobbies or exercise to loosen the tension in daily life. 7, regular health checks, such as regular blood pressure, blood lipids, blood sugar. 8.Early detection of coronary heart disease Coronary heart disease is a common and frequent disease among middle-aged and elderly people. People at this age should seek medical attention for early detection of coronary heart disease when they experience stuffy pain behind the sternum or in the precordial area when they are tired or nervous in daily life. Professor Hu Dayi, a famous cardiovascular specialist, once said that there are 5 lines of defense against coronary heart disease. The first is to prevent the onset of the disease, to “prevent the disease before it happens”; the second is to prevent the event, patients with coronary heart disease should prevent the occurrence of heart attack, stroke (commonly known as stroke) and other serious events; the third is to prevent the consequences, the occurrence of heart attack or stroke should be sent to the hospital in a timely manner to prevent the development of a worse direction; the fourth is to prevent recurrence, to prevent the recurrence of heart attack, stroke, etc.; the last is to prevent heart failure; The last is to prevent heart failure, repeated attacks of heart attack, heart enlargement eventually prone to heart failure. Generally people are most likely to ignore the first line of defense, and only if the first line of defense is done well, more people will have a vibrant heart.
