What are the common misunderstandings about cardiovascular disease

Misunderstanding 1: coronary heart disease and hypertension are the diseases of the elderly

Many young people believe that coronary heart disease and hypertension are the diseases of the elderly, and have nothing to do with themselves. In fact, in terms of hypertension, only in the 6~18 primary school students in China, the incidence rate of hypertension has reached about 8%. Of course, this is partly hypertension secondary to other diseases. But for young people with family history of hypertension, blood pressure should be measured regularly, especially after 30 years old, so as to detect and treat in time, and correct induced blood. High pressure drinking, salty taste and other bad habits. So, what about coronary heart disease? In fact, coronary heart disease is the arteriosclerosis of the heart and blood vessels. This process actually started as early as youth, even in childhood. Of course, due to the influence of heredity, diet, living habits and external environment, different people have different ages of onset, and some people do not even have obvious symptoms in their whole life. Vascular stenosis to a certain extent, or when combined with acute thrombosis will have obvious symptoms. The youngest patient I ever diagnosed with coronary heart disease and myocardial infarction is only 32 years old. It is said that there are still younger patients, which is really a pity. All these remind us that although age is our greatest wealth, it is not a safe. Whether you can make good use of this wealth depends on yourself!

Myth 2: it's not easy to do some exercise. The amount of exercise should be larger

In modern society, the pace of life is obviously accelerated, the competition is fierce, and the work pressure is great. Many people have to work overload, so it is common to stay up late and work overtime. Occasionally, when I relax a little bit, I will remember the saying that 'life lies in exercise'. So I go to the gym to do some crazy exercises, or climb to the top of the mountain in one breath, thinking that if you exercise, you will be healthy. However, the harm may be even greater. Not long ago, two celebrities in China's business circles died suddenly in the gym one after another. These people usually work hard for a long time, their bodies are overloaded, and their diseases have quietly arrived and are ready to go. Once they exercise intensely and exceed their physical endurance, it is not surprising that they will go out of business. The normal practice is to keep 2-3 times a week for about 1 hour. Aerobic exercise is preferred, such as walking, jogging, swimming, cycling, etc. (anaerobic exercise mainly refers to strength training, such as weight lifting, wrestling, etc.). The formula for judging the intensity of exercise is as follows: maximum heart rate = (220 age) & times; 85%; minimum heart rate = (220 age) & times; 70%. If the heart rate measured after exercise is between the maximum and minimum heart rate, then the exercise intensity is appropriate. For example, the heart rate of a 60 year old should be between (220-60) & times; 70% and (220-60) & times; 85%, i.e. 112 to 136 beats / min. After exercise, if the heart rate is lower than 112, it means that the exercise intensity is too low to achieve the exercise effect; if the heart rate exceeds 136, it means that the exercise intensity is too high, which may lead to various accidents. In addition, after the exercise, a little panting, a little sweating, can still speak without being tired, which means that the intensity of the exercise is appropriate. If the activity after panting, sweating, obviously feel tired, even dizziness and other symptoms of discomfort, it shows that the amount of exercise is too large.

Misunderstanding 3: angina pectoris can carry, try not to take medicine

Many patients with coronary heart disease usually suffer from angina pectoris first and try not to take medicine. They think that if they take medicine frequently, they may not be effective in the future. In fact, on the one hand, nitroglycerin is the most commonly used emergency medicine for angina pectoris. Only when such drugs are taken for a long time and the frequency of taking them every day is very frequent, can they produce drug resistance. They can be taken once a day, even once a day Taking three or four times a day will not form drug resistance, and the drug will not be used in the future; on the other hand, when angina pectoris attacks, coronary artery spasm and myocardial ischemia can be treated as soon as possible to relieve coronary spasm, improve myocardial blood supply, reduce the degree of myocardial ischemia injury, and even reduce the possibility of acute myocardial infarction. If you have angina pectoris and take nitroglycerin, the symptoms still remain unchanged after half an hour. You should be highly vigilant whether there is acute myocardial infarction. You should go to the hospital as soon as possible to reduce myocardial necrosis to the greatest extent. It is not too much to say that 'time is the heart muscle'.

Misunderstanding 4: acute myocardial infarction would rather be conservative treatment than surgery

Interventional therapy of coronary heart disease has a history of more than 20 years. Its appearance provides another effective treatment method for coronary heart disease. In addition to being suitable for patients with ineffective or poor drug treatment, it is especially effective for patients with acute myocardial infarction. The chance of vascular recanalization is obviously better than that of drug treatment. The mortality rate in acute phase is reduced from 30% to less than 5%, and it is obviously reduced Less complications. However, some patients with coronary heart disease do not know enough about the new technology and new therapy, and feel that the operation is risky. They are still unwilling to choose the best emergency interventional operation in the emergency time, which causes the missed opportunity of treatment and even life-threatening. Some data show that only 30% of the patients with acute angina pectoris and acute myocardial infarction received emergency interventional surgery within 6 hours after the onset of the disease, and up to 70% of the patients with acute coronary heart disease chose conservative drug treatment for various reasons, and the effect was not ideal. Therefore, patients with coronary heart disease should change this misunderstanding and seek medical treatment as soon as possible when they suspect acute myocardial infarction. In hospitals with interventional treatment conditions, if economic conditions permit, it is undoubtedly a wise choice to adopt emergency interventional surgery.
