Many of the functions of the body of the elderly continue to degenerate and go into failure as they grow older, and heart function is also less sound, so the occasional chest tightness, chest pain and other uncomfortable symptoms are often taken for granted by everyone, no big deal. This is actually a misconception. Angina pectoris is often just a transient, and may be a precursor to myocardial infarction, or even lead to serious arrhythmia and sudden death! Coronary heart disease is one of the most common causes of chest tightness and chest pain in middle-aged and elderly people. According to statistics, it is not uncommon for this to lead to coronary heart disease. Therefore, the public should not be careless when they experience transient chest tightness and chest pain. Especially for middle-aged and elderly people. Why is this? Coronary heart disease is at some level a chronic disease of the elderly and is very prevalent in the middle-aged and elderly population for a variety of reasons, such as middle-aged and elderly, smoking, diabetes, obesity, hypertension, hyperlipidemia, excessive psychological stress, and so on. The more risk factors there are, the more likely it is that chest discomfort is caused by coronary heart disease. Naturally the younger the person has chest pain, the less likely it is to be coronary heart disease, especially in women. How do I know if the cause of chest tightness and chest pain is likely to be coronary heart disease or not? The cause of chest tightness and chest pain in coronary heart disease is myocardial ischemia. The chest pain in the attack of myocardial ischemia in coronary heart disease has the following more typical characteristics, and the more they are met, the more likely it is ischemic chest pain caused by coronary heart disease. The nature of ischemic chest pain is usually dull pain, or a feeling of pressure, or tightness, or a burning sensation, in short, an unbearable and uncomfortable sensation, without local pressure pain. Location of chest tightness or chest pain The location of chest pain or chest tightness is located in the precordial area, which is the projection area of the heart or the back of the middle and lower part of the sternum, about 1 palm size, with a fixed location, accompanied by radiating pain on the inner side of the left upper limb (the side near the trunk). This pain does not run around, it does not hurt here and then move to another place after a while. If there is significant shifting pain, angina is unlikely. When does chest tightness or chest pain occur during exertion, such as when walking fast, climbing a ladder, or when you are excited, and it lasts for a few minutes and is relieved by rest. However, when walking briskly again, similar symptoms appear again and are relieved after rest. This suggests typical exertional angina, suggesting a stenosis of more than 75% in the coronary arteries. How long do the attacks last Chest tightness or chest congestion is paroxysmal, lasting 3-5 minutes at a time, usually no more than 10-15 minutes, and rarely more than 30 minutes. Of course chest discomfort in myocardial infarction may last longer than 30 minutes, but there are usually paroxysmal exacerbations as well. If it lasts more than a few hours, or even a whole day, it always feels uncomfortable and unsupportive here in the chest. It is important to note that although coronary heart disease is an age-related disease, middle-aged and elderly people do need to be doubly careful and vigilant. But in recent years, the increasing incidence of myocardial infarction, etc. can not only be limited to the middle-aged and elderly population, young people suffering from coronary heart disease and heart attack is becoming more and more common, and young people with symptoms should not be careless!
