How does it cause myocardial ischemia?

Myocardial ischemia may be caused by coronary atherosclerotic heart disease, variant angina pectoris, myocardial bridge compression and other reasons.

1, coronary atherosclerotic heart disease

coronary atherosclerotic heart disease is caused by a variety of reasons leading to coronary artery lumen stenosis, can lead to insufficient blood supply to the heart, resulting in myocardial ischemia.

2, variant angina pectoris

variant angina pectoris is caused by coronary endothelial cell dysfunction, inflammatory response, autonomic nervous system imbalance and other reasons, when the coronary artery transient spasm occurs, it will cause myocardial ischemia.

3, myocardial bridge compression

When the heart contracts, it can shuttle under the epicardium of the myocardial bridge produced a certain pressure, may cause myocardial ischemia.
