What are the symptoms of acute coronary syndrome?

Acute coronary syndrome usually occurs chest tightness, precordial pain, nausea and vomiting, dyspnea and other symptoms.

1, chest tightness

due to the existence of plaques in the coronary artery, leading to lumen stenosis, affecting the blood supply of the heart, early onset of chest distress symptoms.

2, precordial pain

due to the rupture of plaques in the coronary artery emboli, resulting in myocardial blood supply reduced, myocardial cells appear ischemia, anoxic necrosis, will produce acidic substances, stimulate peripheral nerves, causing pain, pain more squeeze, can be radiated to the neck, back and other parts.

3, nausea and vomiting

cardiac output decreased, and myocardial cell necrosis, the production of metabolites will stimulate vagus nerve, affect gastrointestinal motility, nausea and vomiting and other symptoms.

4, dyspnea

cardiac ejection decreased, affecting pulmonary circulation, leading to hypoxia, respiratory center excitability increased, breathing difficulties.
