An elderly patient with atherosclerosis experiences reduced blood flow; which mechanism exacerbates thrombus formation due to increased platelet activity?

💡 Explanation

Reduced blood flow promotes platelet adhesion and activation. Elevated ADP stimulates platelet aggregation via the P2Y12 receptor, therefore increasing thrombus size and vascular occlusion. This occurs because ADP amplifies the aggregation signal, rather than relying solely on initial activators like thromboxane A2 or collagen.
