What is it called when the right and left coronary arteries can't supply enough blood to the heart?

Coronary insufficiency refers to the condition where the coronary arteries, specifically the right and left coronary arteries, are unable to supply adequate blood flow to the myocardium (heart muscle). This situation may arise due to various factors such as atherosclerosis, which causes narrowing of the arteries, or other forms of coronary artery disease that impede blood flow. When blood supply is insufficient, it can lead to symptoms such as chest pain (angina) and may progress to more severe conditions like myocardial infarction.

This term is particularly relevant in distinguishing between different pathophysiological states of the heart. While coronary artery disease encompasses a broader range of issues related to the heart's blood supply, coronary insufficiency specifically highlights the inadequate flow of blood to the heart muscle itself.

Myocardial infarction indicates a specific outcome resulting from prolonged inadequate blood flow, often a direct consequence of coronary insufficiency. Cardiac arrest, on the other hand, refers to the sudden loss of heart function and is not specifically tied to the compromised blood supply from the coronary arteries. Therefore, the definition and implications of coronary insufficiency make it the most accurate term for describing the inability of the coronary arteries to supply enough blood to the heart.
