What happens to the heart muscle when Ischemia occurs?

Ischemia occurs when there's a reduction in blood flow to the heart muscle, often due to blocked arteries. This lack of oxygen and nutrients can lead to damage or death of heart muscle cells, resulting in symptoms like chest pain (angina) and, if prolonged, can cause a heart attack (myocardial infarction). The affected heart muscle may become weakened, impairing its ability to pump effectively and potentially leading to further complications. Prompt medical intervention is crucial to restore blood flow and minimize damage.
