Could platelet distribution width predict coronary collateral development in stable coronary artery disease?

Abstract

OBJECTIVE: We hypothesized that hemogram parameters should be related to the development of coronary collateral vessels. For this purpose, we aimed to compare platelet distribution width (PDW) and PDW to platelet ratio (PPR) in subjects withstable coronary artery disease having adequate or inadequate coronary collateral development.METHODS: A total of 398 patients with stable angina pectoris undergoing coronary angiography were enrolled and dividedon the basis of the development of coronary collateral (CCD) (inadequate CCD (n=267) and adequate CCD (n=131). Routinecomplete blood count and biochemical parameters were measured before coronary arteriography.RESULTS: Mean PDW and PPR values of inadequate and adequate CCD groups were 17.5% (10–23) and 12.4% (9.8–22) %,p
