Which of the following is a non-coronary oxygen supply-demand mismatch?

Answer

A non-coronary oxygen supply-demand mismatch refers to a situation where myocardial oxygen demand exceeds supply due to systemic factors rather than a primary pathology within the coronary arteries (such as plaque rupture, thrombosis, or vasospasm). Severe anemia leads to a reduction in the oxygen-carrying capacity of the blood, which results in generalized hypoxia and an imbalance in myocardial oxygen supply and demand without direct coronary artery obstruction. Therefore, severe anemia is classified as a non-coronary cause.
