Myocardial infarction can lead to death. Myocardial infarction and heart failure are two of the most critical conditions in cardiovascular disease, which can lead to sudden cardiac arrest and death at any time. When a patient is diagnosed with myocardial infarction, he or she must be given active and effective treatment. At present, there are chest pain centers in many hospitals, if the patient is considered to be an acute coronary syndrome, we should go to the chest pain center in time, go to the coronary care ward such as a place for treatment in time to carry out coronary angiography, so as to facilitate a clear diagnosis and further treatment. For patients who do not have a chest pain center or whose local treatment conditions are poor and cannot be transported in time, thrombolysis can be used, but the effect of thrombolysis is not as good as coronary intervention, and sometimes there may be cerebral hemorrhage, and there are many constraints on thrombolysis.
