Myocardial necrosis is an academic definition, that is, coronary artery vascular breakdown, or complete occlusion of blood vessels caused by acute ischemia and hypoxia of the myocardium, no blood supply is accompanied by hypoxia, which causes myocardial necrosis, myocardial necrosis is academically known as myocardial infarction. Myocardial infarction is because the coronary arteries of the heart have some problems, why do we say that the coronary arteries of the heart problems will cause myocardial infarction? It is because the heart is the center of our body, if the heart does not beat, we will be dead, then the heart beats, it is necessary to muscle contraction, we call this myocardial contraction, its contraction will be pumping blood, pumping blood, it is necessary to be transported through the coronary arteries to the whole body, if the coronary arteries have a problem, there are problems with the transfusion of blood, there will be myocardial infarction! Acute myocardial infarction is mainly due to the coronary artery plaque rupture caused by the formation of acute thrombus, and this plaque in a certain factor of stimulation such as high blood sugar or a large number of cigarettes lead to plaque instability, resulting in plaque rupture caused by atherosclerosis vascular occlusion, acute occlusion of blood vessels for more than 20 minutes, leading to myocardial persistent ischemia and hypoxia, causing necrosis of the myocardium. Is myocardial infarction equivalent to myocardial infarction? Many people can’t tell the difference between infarction and infarction, and even think that myocardial infarction and myocardial infarction describe the same kind of lesion. But the truth is that myocardial infarction is not the same as myocardial infarction. The difference between myocardial infarction and myocardial infarction Myocardial infarction is a milder lesion than myocardial infarction, and myocardial infarction can become myocardial infarction with further development. Timely treatment of myocardial infarction can alleviate the condition, if the treatment is not timely, further development of myocardial infarction will occur. Studies have shown that most myocardial infarction and myocardial infarction are related to the rupture of unstable atheromatous plaque. Myocardial infarction and myocardial infarction can occur in patients with recurrent angina pectoris, myocardial infarction can lead to severe arrhythmia and heart failure, correctly recognizing the precursors of myocardial infarction can effectively prevent the occurrence and development of myocardial infarction. Coronary heart disease, myocardial ischemia, myocardial infarction these three terms should not be unfamiliar to everyone, but many people may not know the relationship between the three. In fact, coronary heart disease and myocardial infarction are diseases and myocardial ischemia is a disease state, but all three can be categorized as coronary heart disease. Coronary heart disease refers to the narrowing inside the blood vessels due to atherosclerosis inside the vessels supplying blood to the heart, which in turn leads to insufficient blood supply to the heart muscle, resulting in chest tightness, chest pain and other conditions. When a larger branch of a coronary artery becomes completely occluded (thrombosed), the heart muscle supplied by this blood vessel dies because it is not nourished by blood, which is called a heart attack. Myocardial infarction is caused by severe myocardial ischemia, which ultimately leads to necrosis of heart muscle cells. Thus, myocardial ischemia is a disease state, but it is closely related to the development of coronary heart disease and myocardial infarction. The relationship between the two can be stated as follows: coronary heart disease is a broad category, and myocardial infarction is the most serious consequence of coronary heart disease.
