Chest pain 14 hours, did not cause attention, heart failure to the hospital, a large area of myocardial necrosis!

Mr. Liu, 59 years old, had chest pain for 14 hours. He did not pay attention to it until he finally had dyspnea and was unable to hold his breath. He went to the hospital to have an examination of acute myocardial infarction. He had heart failure and hypotension shock. < / P > < p > in fact, this is a completely avoidable myocardial infarction, at least a completely avoidable heart failure. Why always emphasize heart failure? Because heart failure is a very difficult disease, and there is no good way at present. The 5-year mortality rate of chronic heart failure is 50%, and the one-year mortality rate of severe heart failure is 50%. Like some cancers, we all talk about cancer. In fact, heart failure is the same as cancer Serious. < p > < p > one week before myocardial infarction, Mr. Liu had chest pain many times, lasting for 3-5 minutes each time, which could be relieved quickly. It often happens when you go upstairs or walk fast. It can be relieved if you stop. Every time he had chest pain, he wanted to go to the hospital to have a look, but after a few minutes of relief, he gave up the idea of going to the hospital, and so on. < / P > < p > we usually encounter many patients with myocardial infarction, do not know what kind of myocardial infarction alarm, and ultimately delayed. In fact, most myocardial infarction have alarm, unless it is a very small number of the first attack of myocardial ischemia on sudden death, this situation has no time to go to the hospital. The rest of the vast majority of myocardial ischemia before myocardial infarction, there will be clues, there will be a reminder. < / P > < p > every time angina pectoris of simple hand is the alarm of myocardial infarction. As long as we can understand the knowledge of angina pectoris, we can go to the hospital in time. After regular treatment, we can avoid myocardial infarction. There are many manifestations of angina pectoris, the common is the pain in the anterior area or chest pain, but there are many manifestations, such as toothache, headache, back pain, shoulder pain, upper abdominal pain may be angina pectoris. There are chest tightness, sweating, pharyngeal tightness may also be angina pectoris. If these symptoms last for 2-15 minutes each time, and appear more than after activity, or worsen after activity, they will be relieved after rest. After remission, it’s just like a healthy person. Then you must consider angina pectoris, go to the hospital as soon as possible, if it is angina pectoris is the alarm of myocardial infarction. Angina pectoris is a kind of myocardial ischemia caused by severe cardiovascular stenosis. When myocardial infarction occurs, cardiovascular blockage occurs and persistent myocardial ischemia occurs. < / P > < p > even if Mr. Liu didn’t see a doctor in time when he had angina pectoris, but when he had chest pain for 14 hours today, if he dialled 120 at the first time and went to the hospital to open blood vessels at the first time, there would be no more myocardial necrosis. If there was no more myocardial necrosis, there would be no heart failure, and if there was no heart failure, life expectancy would not be shortened. < / P > < p > the occurrence of myocardial infarction is that the cardiovascular system is suddenly blocked by thrombus, and then the heart will stop at any time. With the duration of vascular blockage, more myocardial necrosis and more myocardial necrosis, the risk of heart failure will be increased linearly. The necrotic area was about 30% of the total ischemic area after 40 minutes of occlusion, 50% after 3 hours of occlusion and 70% after 6 hours of occlusion. < p > < p > Mr. Liu’s chest pain lasted for 14 hours, but he did not pay attention to it. He endured it until a large number of myocardial necrosis, heart failure and dyspnea occurred. He was forced to go to the hospital to see him. As a result, almost all the infarcted blood vessels and myocardium were necrotic, and the myocardial enzymes were about 20 times higher. < p > < p > from the ECG analysis, Mr. Liu’s myocardial infarction area was not too large, if you can see a doctor in time and open the blood vessels in time, then heart failure will certainly be avoided. But now this kind of small myocardial infarction, because of the late treatment, almost all the myocardial in the blocked area is necrotic, and when the heart failure occurs, the blood pressure also drops to 95mmhg. The mortality rate of this kind of acute myocardial infarction is very high. < / P > < p > if Mr. Liu has a little common sense of angina pectoris, he will go to the hospital a few days ago, so as not to have myocardial infarction; if Mr. Liu has a little common sense of myocardial infarction, he will go to the hospital at the first time to open blood vessels and avoid heart failure. 08/16/2020
