Is there a symptom of myocardial infarction?

Whether there are signs of myocardial infarction needs to be analyzed according to the specific situation.

If the patient's congenital pain threshold is high and the collateral circulation is well established, it is usually difficult to perceive symptoms, so there is no obvious sign of myocardial infarction. However, if the patient's congenital pain threshold is low and the collateral circulation is relatively poorly established, the onset of myocardial infarction may show signs such as chest tightness, tightness in the throat, palpitations, shortness of breath, and irritability.

It is recommended that patients with myocardial infarction pay more attention to rest, do not overwork, and keep a light diet., try to focus on low salt, low fat and low cholesterol, and eat more fruits and vegetables.
