Myocardial infarction always happens suddenly? In fact, there is a warning before the attack. Remember, it can save lives

Acute myocardial infarction, is a very dangerous disease, everyone’s impression of it is always sudden, in a few minutes will take human life. There are many people asked huazi, myocardial infarction before the occurrence of what omen, how can be prevented? In fact, before the onset of most myocardial infarction, early warning will be issued, but some precursory symptoms are not obvious and are easy to be ignored by patients. If the high-risk population of cardiovascular disease, pay more attention to these symptoms, can greatly increase the success rate of saving their lives. < / P > < p > for sudden myocardial infarction, many people have the impression that a “good end” person falls down for no reason. But in fact, no one will fall for no reason. Most of the diseases that seem to happen suddenly are “premeditated for a long time”. The vast majority of myocardial infarction occurs on the basis of coronary atherosclerosis. When the artery intima is damaged, cholesterol will enter into the artery intima to form atherosclerotic plaque. If not intervened, the plaque will be longer and larger, resulting in vascular stenosis. However, when the degree of coronary artery stenosis is less than 50%, it will not affect the blood supply of the heart and will not produce symptoms, and the patient will not have any feeling. However, the probability of AMI is not related to the degree of coronary artery stenosis, but to the stability of plaque. Unstable atherosclerotic plaques are prone to collapse. The surface of the plaque will activate platelet aggregation, and then activate fibrin to form thrombus, resulting in vascular blockage and myocardial hypoxia and ischemia. However, atherosclerotic plaques in arteries can not be formed overnight, but take several years to gradually progress to the level of pathogenicity. Therefore, myocardial infarction just seems to happen “suddenly”, but in fact, those who suffer from myocardial infarction have been ill for several years or even more than ten years. Precursory symptoms: more than half of myocardial infarction will have precursory symptoms a few days before the onset, such as chest discomfort, fatigue, palpitation, irritability, shortness of breath and other symptoms. In particular, we should pay attention to the abnormal angina pectoris, such as angina pectoris, angina pectoris, angina pectoris, angina pectoris, angina pectoris, angina pectoris, angina pectoris with different pain patterns. < / P > < p > these symptoms may be relieved quickly after the onset, but they can not be ignored, because they often mean more serious conditions. Therefore, it is suggested that people with these symptoms should go to the hospital immediately. Pain of unknown origin: pain and tightness in the anterior chest area are usually manifested at the beginning of myocardial infarction. More in the morning attack, can not be relieved. It may also be accompanied by sweating, fear, irritability and a sense of near death. < / P > < p > some people have atypical pain parts, which may be manifested as stomach pain, shoulder pain, back pain, neck pain, and even toothache. Therefore, people with high risk of cardiovascular disease should be careful as long as they have unexplained pain. It is recommended that they go to the hospital for examination as soon as possible. Other symptoms: when myocardial infarction occurs, there may be gastrointestinal symptoms, such as nausea, vomiting, or abdominal distension. There are also patients with mental disorders due to decreased cardiac output, insufficient blood supply to the brain and lack of oxygen, showing that they have never suffered from mental illness, but suddenly utter nonsense. < / P > < p > 4, pay attention to incentives: some things may induce myocardial infarction, such as great joy, great sorrow, anger and other intense emotional changes, so we should learn to control emotions and maintain peace of mind. There are also violent activities, satiety diet is also a common inducement, so to avoid strenuous exercise, avoid constipation, do not force defecation, eat to maintain seven, eight full can. < / P > < p > in fact, myocardial infarction can be prevented by drugs. We have drugs to stabilize the plaque, which can make the atherosclerotic plaque in the coronary artery smaller, more stable and less prone to collapse. We also have antiplatelet drugs that inhibit platelet aggregation when plaque breaks down, thereby avoiding thrombosis. However, there is a prerequisite for drug prevention, that is, a clear diagnosis is needed, and it is necessary to identify people with high risk of cardiovascular disease. Many people with myocardial infarction do not have the habit of physical examination, so they don’t know that they have been “sick”, so they will not carry out drug prevention. < / P > < p > it is suggested that people with hypertension, hyperlipidemia and hyperglycemia should go to the hospital for physical examination regularly. But ECG and color Doppler ultrasound can not see whether there is atherosclerosis in the coronary artery. It is necessary to estimate the situation of atherosclerosis through carotid color Doppler ultrasound and fundus artery examination. People with high possibility of atherosclerosis can do coronary angiography, which is the “gold standard” for the diagnosis of coronary artery. < / P > < p > for the high-risk population diagnosed with cardiovascular disease, medication must be under the guidance of doctors. One thing we need to understand is that drugs can only control risks, not eliminate risks. Therefore, drugs need to be taken regularly for a long time to play a preventive role. Never adjust the dosage or stop taking drugs by yourself. < / P > < p > to sum up, in fact, the occurrence of myocardial infarction is not “sudden”, but sometimes the “early warning” is not obvious, which is easy to be ignored by patients. This requires that we usually pay more attention to their own body, regularly go to the hospital for physical examination, and master more health knowledge, so as to minimize the threat of myocardial infarction to health.
