Acute myocardial infarction symptoms

There is no clinical initial symptom of acute myocardial infarction, but the symptoms of acute myocardial infarction include precordial pain, chest distress, dyspnea, etc. The specific analysis is as follows:

1. Precordial pain After

acute myocardial infarction patients suffer from illness, myocardial blood perfusion is reduced, so that the precordial region lacks blood nourishment, causing pain.

2.

Coronary artery blood flow in patients with chest distress is reduced, affecting local blood circulation, leading to myocardial ischemia, resulting in chest distress.

3. Dyspnea. The

systolic and diastolic functions of patients with acute myocardial infarction are reduced, affecting cardiac ejection capacity, leading to ischemia and hypoxia of peripheral organs, affecting respiratory system and causing dyspnea.
