The hallmark of ACS pathophysiology is:

Answer

Acute coronary syndrome (ACS) refers to a spectrum of conditions compatible with acute myocardial ischemia, which is typically caused by the rupture or erosion of an atherosclerotic plaque with subsequent platelet activation and thrombus formation. The fundamental pathophysiology underlying ACS is an imbalance between myocardial oxygen supply and myocardial oxygen demand (often resulting from a sudden reduction in coronary blood flow due to a thrombus). While complete or partial coronary occlusion is a mechanism, the broad hallmark is the supply-demand mismatch leading to ischemia and potential infarction.
