What are the common misunderstandings in the concept of cardiovascular disease?

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

Many young people believe that coronary heart disease and high blood pressure 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 blood 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. In fact, this process has begun as early as youth, even childhood. Of course, due to the influence of heredity, diet, living habits and external environment, different people have different age of onset, and some people even have no obvious symptoms in their whole life. Vascular stenosis only to a certain extent, or combined with acute thrombosis will have obvious symptoms. The youngest patient with coronary heart disease and myocardial infarction I have ever treated 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!

Misunderstanding 2: it's not easy to exercise, but the amount of exercise should be larger

In modern society, the pace of life is obviously speeding up, the competition is fierce, and the work pressure is great. Many people have to work overload, so it is common for them to stay up late and work overtime. Once in a while, when I relax, I think of the saying that life lies in exercise. So I go to the gym to practice wildly, or climb to the top of the mountain in one breath, thinking that if I do exercise, I will be healthy. However, the harm of doing so may be greater. Not long ago, two celebrities in the domestic business circle suddenly died in the gym one after another. It's a pain in the neck! These people usually work hard for a long time, and their bodies are overloaded. The disease has quietly arrived, and they are ready to go. It's not surprising that once they take intense exercise and exceed their physical endurance, they will go out of business. The normal practice is to keep 2-3 activities a week, lasting about 1 hour each time. Aerobic exercise is better, such as fast walking, jogging, swimming, cycling, etc. (anaerobic exercise mainly refers to strength training, such as weight lifting, wrestling, etc.). The formula to determine 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. If the heart rate is lower than 112 after exercise, it means that the exercise intensity is too low to achieve the effect. If the heart rate is higher than 136, it means that the exercise intensity is too high, which may lead to various accidents. In addition, after the exercise, a little wheezing, slightly sweating, can still speak but not tired, it means that the intensity of the exercise is appropriate. If after the activity panting, sweating, obviously feel tired, even dizziness and other symptoms, it means that the amount of exercise is too large.

Mistake 3: angina can carry on, try not to take medicine

Many patients with coronary heart disease usually suffer from angina pectoris and try not to take drugs. They think that if they take drugs often, they may not be effective in the future. In fact, on the one hand, nitroglycerin is the most commonly used first aid drug for angina pectoris. Only when they take these drugs for a long time and the frequency of taking them every day is very high, can they develop drug resistance. They occasionally take them once a day, even once a day On the other hand, when angina pectoris attacks, coronary artery spasm and myocardial ischemia, early administration can relieve coronary artery spasm, improve myocardial blood supply, reduce the damage degree of myocardial ischemia, and even reduce the possibility of acute myocardial infarction. If you have angina pectoris and take nitroglycerin, the symptoms are still not relieved half an hour later. You should be highly alert to 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 myocardial infarction'.

Myth 4: acute myocardial infarction would rather be treated conservatively than operated

Interventional therapy for coronary heart disease has a history of more than 20 years. It provides another effective treatment method for coronary heart disease. In addition to the ineffective or poor effect of drug treatment, it is especially effective for patients with acute myocardial infarction. The chance of recanalization is significantly better than that of drug treatment. The mortality rate in acute phase is reduced from 30% to less than 5%, and it is significantly reduced Less complications. However, some patients with coronary heart disease know too little about new technologies and new therapies, and feel that surgery is risky. They are still reluctant to choose the best emergency intervention surgery in an emergency, resulting in missed treatment opportunities and even life-threatening. Some data show that only 30% of 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 patients with acute coronary heart disease chose conservative treatment due to various reasons, the effect is not ideal. Therefore, patients with coronary heart disease should change this misunderstanding, and seek medical treatment as soon as possible when suspected of acute myocardial infarction. In hospitals with interventional treatment conditions, if economic conditions permit, it is a wise choice to adopt emergency interventional treatment.
