Survey results show that 62% of people over 40 years old in China already have cardiovascular disease or risk factors to varying degrees, and 80% of them do not yet fully understand how to keep their hearts healthy. People with coronary heart disease or risk factors for coronary heart disease should do their best to prevent myocardial infarction and pay attention to the following points in their daily lives: 1. Do not lift heavy objects. Lifting heavy objects is bound to bend over and hold your breath, which has a similar effect on the respiratory and circulatory system as holding your breath with force to defecate, and is a common cause of heart attack in elderly coronary heart patients. 2, relaxed spirit, happy life, to be able to take anything lightly. 3, bathing to pay special attention, do not take a bath in the case of a full meal or hunger. Water temperature is best with body temperature, the water temperature is too hot can make the skin vascular expansion, a large amount of blood flow to the surface of the body, can cause ischemia. Bathing time should not be too long, the bath room is hot and not ventilated, in such an environment of high metabolic level, very easy to lack of oxygen, fatigue, elderly patients with coronary heart is even more so. The more serious degree of coronary heart disease patients bathing, should be carried out with the help of others. 4, climate change to beware. Under the influence of severe cold or strong cold air, the coronary arteries can spasm and secondary thrombosis and cause acute myocardial infarction. When the climate changes sharply and the air pressure is low, patients with coronary heart disease will feel obvious discomfort. Domestic data show that persistent low temperature, high wind and cloudy rain is one of the triggers of acute myocardial infarction. Therefore, whenever the climate is bad, patients with coronary heart disease should pay attention to keep warm or take nitroglycerin-like crown-expanding drugs appropriately for protection. 5, but also to know and identify the aura symptoms of infarction and give timely treatment. About 70% of myocardial infarction patients have aura symptoms, mainly manifested as follows: (1) sudden and obvious aggravation of angina attack; (2) change in the nature of angina than before or not easily relieved by nitroglycerin; (3) pain accompanied by nausea, vomiting, sweating or obvious bradycardia; (4) sudden appearance of unexplained arrhythmia, heart failure, shock, dyspnea or syncope in elderly patients with coronary artery disease. The aura symptoms of myocardial infarction mostly appear 1 week before the onset, and in a few patients even weeks earlier. Once the above symptoms occur, it is important to take them seriously and seek medical attention in a timely manner. In addition to the precautions you should take in daily life, you also need to adhere to medication. It mainly includes drugs to reduce platelet aggregation, control blood pressure, lower blood lipids and control blood sugar. Aspirin is an inexpensive and effective anti-platelet aggregation drug. In patients with risk factors for atherosclerotic diseases, aspirin treatment can reduce the overall risk of myocardial infarction and coronary heart disease death by 1/3-1/4, and it is now recommended as one of the essential drugs for the prevention and treatment of cardiovascular diseases in countries all over the world. In addition, statin lipid-lowering drugs can stabilize plaque and should be taken consistently by patients with coronary heart disease. It is only by strengthening prevention that the occurrence of myocardial infarction can be reduced.
