As a medical professional with expertise in cardiology, I can explain the causes of ischemic pain. Ischemic pain is typically caused by a lack of oxygen-rich blood supply to the tissues of the heart muscle, which is known as myocardial ischemia. This condition can be asymptomatic, or it can manifest as chest pain, commonly referred to as angina pectoris. The most common cause of ischemic pain is atherosclerosis, which involves the buildup of plaques that are rich in cholesterol within the coronary arteries. These plaques can narrow the arteries, reducing the flow of oxygenated blood to the heart muscle, which in turn leads to ischemia and the associated pain. read more >>

Cardiac ischemia may be asymptomatic or may cause chest pain, known as angina pectoris. It occurs when the heart muscle, or myocardium, receives insufficient blood flow. This most frequently results from atherosclerosis, which is the long-term accumulation of cholesterol-rich plaques in the coronary arteries.read more >>
