After the occurrence of acute myocardial infarction can be successfully treated with the consultation time is related to the early and late, as follows: 1, time early will certainly save more necrotic myocardium on the brink of death, can be saved. Especially now after the intervention, many patients into the hospital soon on the stage to open the blocked blood vessels, can be saved; 2, delayed admission time, lose the best time to save, the whole myocardial necrosis quickly spread, the heart beat affected, resulting in pump failure, can not be saved; 3, the patient would have come in a timely manner, but due to the blockage of the blood vessels are more important, such as the left trunk blockage, the anterior descending branch of the cyclotron branch of the vessel all blocked, the whole heart can be saved. However, due to the blockage of more important blood vessels, such as after the blockage of the left main trunk, the anterior descending branch of the gyration branch of the blood vessels are all blocked, the entire heart muscle of the main left ventricular anterior wall does not move, the pump failure state is very serious, so even if the timely delivery to the hospital, can not be saved.
