The relation of aortic stiffness and in-stent restenosis in patients undergoing percutaneous coronary stenting.

Background: There is a suggestion that increased aortic stiffness can be the early manifestations of the atherosclerosis process and is related to decrease coronary flow after coronary stenting. We aimed to evaluate whether aortic stiffness could predict occurrence of in-stent restenosis (ISR) and its relation to coronary flow reserve (CFR) after coronary artery stenting.

Methods And Results: The study population included 126 patients with single vessel coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) with bare-metal stenting and at least 12 months of follow-up.
