Repeated myocardial ischemia? Although it is not a disease, it is also necessary to be vigilant and do these 4 points well

The words "myocardial ischemia" must be heard by everyone in daily life. Many people mistakenly believe that myocardial ischemia is a disease.

　　But in fact, it refers to the reduction of blood perfusion to the heart, resulting in the heart being in a state of ischemic oxygen and abnormal myocardial energy metabolism. It is not a disease in itself, but a case state.

　　You must know that almost all the energy required for cardiac activity needs to be carried out under the condition of aerobic metabolism . Even if the human body is in a completely quiet state, the uptake of blood oxygen by the myocardium is very high, reaching about 70 %.

　　Under normal circumstances, the body has a perfect self-regulation mechanism, which can promote the relative balance of blood supply and keep the heart working normally. However, under the influence of certain factors, the supply and demand of myocardial blood will be unbalanced, which will eventually develop into myocardial ischemia.

　　A survey of relevant data shows that in recent years, the prevalence of myocardial ischemia in China has shown an increasing trend year by year, among which middle-aged and elderly people are the most common. However, under the influence of many aspects such as the increase in bad life and eating habits, and environmental changes in recent years, some young people in their 20s and 30s have also developed myocardial ischemia.

　　Judging from the current clinical data, myocardial ischemia is actually based on coronary atherosclerosis, inflammation and other diseases in most cases. However, it also has associated risk factors, such as the following points that need to be vigilant:

1. Improper diet

　　It has to be said that the living conditions of contemporary people have made a qualitative leap compared with the early days of the founding of the People's Republic of China. Delicious foods that were not always available on New Years and festivals have actually become family meals.

　　But it is this change that has become a breakthrough for diabetes, hyperlipidemia, and hypertension . For example , eating a lot of high-fat, high-protein, high-sugar, and high-calorie foods for a long time will easily lead to metabolic disorders, obesity and other problems, which in turn increases the risk of myocardial ischemia;

2. Smoking and drinking

　　The nicotine in cigarettes is not only the culprit of addiction, but it also has a negative impact on the cardiovascular and cerebrovascular system, which promotes the gradual damage of arteries and the appearance of atherosclerosis . And these substances also have stimulant effects, which can lead to faster heartbeat and higher blood pressure in smokers .

　　The same is true of alcohol. It not only has the effect of dilating blood vessels, but also can cause atherosclerosis . Long-term smoking and alcoholism are undoubtedly burying hidden dangers for cardiovascular and cerebrovascular diseases;

　　3. Excessive fatigue

　　Due to the accelerated pace of work and life, and the level of economic consumption is getting higher and higher, everyone's daily work and life pressure is quite large. Many young people go to work and family every day, leaving their bodies in a state of excessive fatigue.

　　Some related studies have shown that chronic fatigue stress is one of the reasons for myocardial ischemia in young and middle-aged people, and it is also the cause of premature coronary heart disease . Excessive fatigue accounts for about 65-80% of sudden cardiac death ;

4. Lack of exercise

　　Relevant research and surveys show that due to work factors, electronic products and other factors, Chinese residents spend more than 10 hours a day sitting for long periods of time , and many people are not interested in exercise.

Prolonged sitting for a long time is not only the cause of obesity, but also affects the speed of blood circulation and accelerates the formation of atherosclerosis. Over time, it can affect the blood supply of the myocardium and eventually lead to myocardial ischemia .

　　In conclusion, myocardial ischemia is both a symptom of a disease and a physical manifestation of pathology. Once myocardial ischemia is excessive, it will lead to myocardial necrosis, sudden myocardial infarction, and even the risk of sudden death.

　　Therefore, everyone should be more vigilant about myocardial ischemia, and it is necessary to stay away from unhealthy living and eating habits in life.
