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? In fact, the onset of myocardial infarction population is getting younger and younger is traceable, mainly in the following three aspects: Nowadays, many teenagers like to play games online, but due to the lack of control is easy to become too excited psychological emotions, too much energy focused on the game plot, but also cause too much mental tension. This may not only cause blood pressure to rise, heart rate increase, myocardial oxygen consumption surge, aggravate myocardial ischemia, but also can cause coronary artery spasm contraction to myocardial ischemia and necrosis. Some young people engaged in high-intensity physical labor or strenuous exercise, etc., can cause the heart rate to increase, blood pressure to rise, the heart is overburdened, resulting in insufficient blood supply to the existing myocardium aggravated, resulting in acute necrosis of part of the heart muscle. Of course, this situation is not common. The most easily neglected are the obese adolescents with relatively high blood lipids, high blood viscosity and ischemia in the heart muscle. For these patients, if they exercise too much, it will make the blood pressure suddenly rise and the blood viscosity also increase, which will lead to narrowing of the coronary arteries and slow local blood flow, making it easy for acute myocardial infarction to occur. Smoking is the main cause of 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 blood’s ability 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 acute and dangerous, why is this? 1, mostly for the first time: unlike the elderly or long-term myocardial ischemia patients, the majority of young and middle-aged myocardial infarction for the first time. 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 past 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 can not be paralyzed, do not think that myocardial infarction is a disease only for the elderly, so that you can have a healthy and complete life!
