The survival time of patients after acute infarction cannot be generalized and is related to the size of infarction, the site of infarction, and the timeliness of treatment. If the acute infarction occurs in a non-critical area and the lesion is small, the survival time of the patient will not be affected by timely early thrombolysis, anticoagulation, infusion, coronary intervention and other active treatment. If the acute infarction is not treated in a timely and effective manner or is combined with serious complications, the patient may have only a few hours left to live. If the acute infarction occurs in the anterior descending branch and other important parts of the heart or the area is large, the patient may not be able to save the treatment, and instant death can occur. Acute heart attack patients usually do not overwork, pay attention to rest, do not get too excited, quit smoking and drinking, control blood sugar, blood fat, blood pressure. If there is pain in the anterior region of the heart, it is recommended to go to the cardiovascular department of the nearby tertiary hospital in a timely manner.
