What causes stress induced ischemia?

Stress-induced ischemia occurs when the heart muscle doesn't receive enough oxygen-rich blood during periods of increased physical or emotional stress. This can result from narrowed coronary arteries due to atherosclerosis, which limits blood flow. Factors such as high blood pressure, elevated heart rate, and increased oxygen demand during stress can exacerbate the condition, leading to symptoms like chest pain or discomfort. Ultimately, the mismatch between the heart's oxygen supply and demand triggers ischemia.
