Myocardial infarction, a disease that people may think is only for the elderly, can actually also “visit” young people! The proportion of myocardial infarction in young people has been growing rapidly in recent years and has become a focus of attention, with the population of myocardial infarction gradually developing towards a younger trend. Why is this so? Is the heart of young people more “fragile” than that of the elderly? Myocardial infarction incidence of the younger population is traceable, mainly in the following three aspects A. Play games Nowadays, many teenagers like to play games online, but due to the lack of control is easy to cause psychological emotions too excited, too much energy focused on the game plot, but also cause too much mental tension. This may not only cause an increase in blood pressure, heart rate, myocardial oxygen consumption surge, aggravating myocardial ischemia, but also can cause coronary artery spasm contraction to myocardial ischemia and necrosis. Second, strenuous exercise Some young people engaged in high-intensity physical labor or strenuous exercise, etc., can cause the heart rate to increase, blood pressure, the heart is overburdened, causing the existing myocardial blood supply deficiency aggravated, resulting in acute necrosis of part of the myocardium. Of course, this situation is not common. The most easily neglected are the obese adolescents, who have relatively high blood lipids and high blood viscosity, and whose myocardium is already ischemic. For this part of the patient, once the exercise is too much, will make the blood pressure suddenly rise, blood viscosity also increased, which will lead to coronary artery narrowing local blood flow slow, very easy to occur acute myocardial infarction. Third, smoking Smoking is an important factor in triggering acute myocardial infarction, whether active or passive smoking, and the occurrence of myocardial infarction and the amount of smoking is also closely related. Nicotine in cigarettes can cause increased blood pressure, increased heart rate, increased myocardial oxygen consumption, carbon monoxide in the smoke into the blood, so that the ability of the blood to carry oxygen is reduced, aggravating myocardial ischemia, nicotine and carbon monoxide can cause coronary spasm, leading to the occurrence of acute myocardial infarction. Therefore, I advise all young people to stay away from tobacco as soon as possible. The mortality rate of myocardial infarction is higher in young people If myocardial infarction occurs in young people, it is very easy to cause acute ischemic necrosis of myocardial tissue, complicated by electrophysiological disorders of myocardial tissue, lethal arrhythmias, cardiogenic shock and other critical illnesses. Compared to the condition of elderly patients, it is more urgent and dangerous, why is this? Unlike the elderly or patients with long-term myocardial ischemia, the majority of young and middle-aged patients with myocardial infarction have their first onset. 2, lack of “ischemic preconditioning” Before the onset of the disease, the underlying lesions of the coronary vessels that nourish the myocardium are usually mild, without significant plaque and fixed stenosis, so the heart fails to establish the protective effect of vascular collateral circulation and myocardial ischemic preconditioning (so-called “ischemic preconditioning”). The so-called “ischemic preconditioning”, i.e., repeated transient myocardial ischemia has a protective effect on subsequent longer-term myocardial ischemia and can improve the tolerance of myocardial tissue to ischemia). 3, ignore early symptoms In addition, due to their previous good health, young people are easy to ignore even early signs of discomfort and delay seeking medical attention, thus missing the best time for emergency treatment. In short, when you are young, you must take extra care of your body, stay away from the triggering factors of myocardial infarction, some subtle early symptoms should not be paralyzed, and do not think that myocardial infarction is a disease that only the elderly have.
