Myocardial infarction is a clinical type or manifestation of coronary atherosclerotic heart disease (coronary heart disease for short), which is caused by acute ischemic and hypoxic necrosis of the myocardium due to acute thrombosis caused by rupture of unstable plaque in the coronary arteries. In the eyes of ordinary people, coronary heart disease is only a disease of the elderly and has nothing to do with young people, which is a wrong view or opinion. With the development of society and the acceleration of the pace of life and work, the improvement of living conditions and the increase of survival pressure, coronary heart disease and myocardial infarction also began to patronize more and more young people, coronary heart disease is no longer the patent of the elderly. The symptoms and prognosis of myocardial infarction in young people are different from those of myocardial infarction in elderly people because of their age, experience, physical condition and the special characteristics of the heart structure itself, and they also need extensive social and medical attention and attention because of their social and family responsibilities and contribution to society. The World Health Organization, through the analysis of thousands of cases of acute myocardial infarction in young people and long-term follow-up observations in several large cardiac research centers around the world, concluded that “myocardial infarction in young people is more dangerous than in older people.” The main reason for this is that young people do not pay enough attention to the disease, and the onset of the disease is fast and often too late to save. The following differences exist between myocardial infarction in young people and myocardial infarction in the elderly: 1. Young people are confident that they are physically strong, eat well and sleep well, ignore the early symptoms of the disease, even if there is chest tightness, chest pain and so on, they think they can get over it, do not pay attention to it, and miss the opportunity to seek medical treatment and the time for first aid. 2, young people often do not have any signs at the onset of myocardial infarction. Because of coronary heart disease young people have light coronary artery lesions, that is, the coronary stenosis is not particularly serious, but basically unstable soft plaque, very easy to rupture or produce cracks caused by acute thrombosis. And a very large proportion of myocardial infarction in young people has the factor of coronary spasm, especially in young women. 3, young people because of the relatively light coronary lesions, lack of ischemic pre-adaptation of the myocardium, often occur when the symptoms of myocardial infarction is very serious, so that shock, heart failure and sudden death and other dangerous prognosis. Many cardiologists believe that the lack of ischemic preadaptation of the myocardium is the key to the more dangerous prognosis of myocardial infarction in young people. The key to disease is prevention and early treatment, and it is often a sad day for patients, families, doctors, and even society when the disease is so advanced that surgery is not an option or cannot be solved by surgery! This is especially true of myocardial infarction in young people. How can we prevent coronary heart disease myocardial infarction? 1, the diet is light, rich in vitamins and protein, fat-rich and cholesterol-rich food eat less, eat on time, diet should be moderate, do not overindulge in dinner, night snacks as little as possible, do not overeat; 2, maintain good habits is very critical. Life should be regular, avoid long-term late night work, early to bed and early to rise, not less than 6 hours of sleep each night, natural awakening in the morning is often a sign of adequate sleep. Never ignore the importance of water in daily life for the body, timely hydration (preferably plain water), can avoid increased blood viscosity and thrombosis, as well as the role of anti-aging skin. 3, develop the habit of insisting on exercise. According to personal preferences and the surrounding living conditions, choose the appropriate aerobic exercise, each lasting more than 30 minutes, more than 3 times a week, is conducive to weight control, enhance cardiopulmonary function, increase myocardial blood supply and heart reserve function; for patients with coronary heart disease, moderate exercise is conducive to the establishment of coronary collateral circulation. 4, do not smoke, less alcohol. It is clear that smoking is a very important risk factor for coronary heart disease. Smoking produces tar, nicotine and other harmful components that cause coronary artery spasm, resulting in myocardial ischemia and hypoxia. In young people who have myocardial infarction, most of the coronary angiography can be completely normal, and post-mortem examination does not reveal pathological changes of coronary atherosclerosis. Studies have proven that smoking, mental overstrain, overexertion and alcoholism can cause coronary artery spasm, resulting in cardiac electrophysiological disorders, causing serious arrhythmias, on the basis of which thrombus is formed and blocking the coronary arteries, resulting in myocardial infarction. 5, maintain a calm state of mind, learn to release pressure. Young people are in the rising stage of career development, is a competitive age, hoping to make certain achievements in every aspect beyond others, looking forward to get ahead and be appreciated by their bosses. But not every idea can become reality, frustration and failure accompany everyone’s growth. To face the gap between their own efforts and the expectations of their bosses or their own goals, to avoid great joy and sadness, find a good friend to chat, drink is a better way to release pressure. 6, regular health checkups, early intervention of risk factors related to myocardial infarction such as hypertension, hyperlipidemia, diabetes, etc., early detection, early prevention, early treatment can help prevent the occurrence of myocardial infarction in young people.
