A night of heart pain, chest distress, shortness of breath, what's going on?

A night of heart pain, chest tightness and shortness of breath may be caused by angina pectoris, acute myocardial infarction, heart failure and other factors, the specific analysis is as follows:

1. Angina

pectoris will make coronary artery blood supply insufficient, cause myocardial spasm, make myocardial oxygen supply insufficient, lead to hypoxia in the body, thus the above conditions occur.

2. Acute myocardial infarction

Acute myocardial infarction will make coronary artery occlusion, leading to myocardial necrosis, necrotic metabolites stimulate the heart, affect cardiac relaxation and contraction, can not give the body oxygen in time, appear overnight heart pain, chest tightness, shortness of breath phenomenon.

3. Heart failure

Heart failure will make the heart unable to effectively pump blood, resulting in insufficient body blood volume, causing myocardial spasm, but also make lung ventilation function decline, overnight heart discomfort, chest tightness and other conditions.
