2) Myocardial Infarction
The blood flow to the heart muscles decreases then completely stops. At this time, the heart muscle dies (myocardial infarction). It occurs due to blockage of the artery that supplies the heart muscles. A myocardial infarction may be transmural or subendocardial.
Transmural infarction includes all thicknesses of the heart wall, while subendocardial infarction involves a part of the heart wall. The most common cause of myocardial infarction is thrombosis on top of atherosclerosis.
In myocardial infarction, you will have chest pain, which you can differentiate from anginal pain. This pain is more severe and prolonged, and the rest doesn’t relieve it. If you have diabetes, you may have a silent myocardial infarction, which is more dangerous. In addition to chest pain, you may feel shortness of breath, nausea, palpitation, sweating, and dizziness.
