Supports local platelet activation after PTCA; hypothesis-generating and should not yet change practice.
Does PTCA increase platelet activation and endothelial injury markers compared to diagnostic coronary angiography in patients with coronary artery disease?
PTCA induces early activation of circulatory platelets in the coronary sinus, likely due to balloon-induced vascular endothelial injury, highlighting the need to minimize vascular trauma during the procedure.
Inoue et al. (1996) studied this question.
