The reasons for the increase of myocardial infarction among young people are generally as follows: the fast pace of work and life, increased survival and psychological pressure, which puts people in a highly tense mental state for a long period of time; the reduction of physical labor, the change of dietary structure and the environmental pollution are also easy to cause physiological disorders of the blood vessels, the nervous system, the endocrine system, and the immune system, and so on. The above factors lead to endothelial damage of the vascular wall of the heart, the gradual thickening of the vascular endothelium, as well as the formation of atherosclerotic plaques significantly accelerated, which are the basic causes of myocardial infarction. When there is a continuous late night, excessive fatigue, smoking and alcoholism, dietary disorders, etc., the human blood vessels will continue to spasm and contract, blood viscosity increases, the local formation of thrombus, and ultimately lead to the sudden occurrence of vascular occlusion, myocardial infarction. Such sudden onset of disease is increasingly showing a trend of youthfulness. As a result, the medical community has revisited the traditional age limit for myocardial infarction, calling for increased vigilance in the development of myocardial infarction in young and middle-aged people. It is important to note that young people tend to be more critically ill and even more likely to die suddenly in the event of a myocardial infarction than older people, usually with a rapid onset and aggressive symptoms. They generally regard themselves as healthy, and even if they are not feeling well, they are easily ignored and delayed in seeking medical treatment, thus missing the best time for emergency treatment. Therefore, young people should be highly alert and seek medical treatment as soon as they experience typical signs of myocardial infarction, such as persistent chest pain, chest tightness and cold sweat, after staying up late or being overworked.
