Background and OBJECTIVES: Increased arterial stiffness is an accepted cardiovascular risk factor. However, the effect of arterial stiffness on the performance of percutaneous coronary intervention (PCI) is not well known. The aim of this study was to evaluate the impact of arterial stiffness measured by pulse wave velocity (PWV) on late loss after percutaneous coronary intervention according to diabetes.
METHODS: Data from 242 consecutive patients who underwent PCI using drug eluting stents and pulse wave velocity study were analyzed.
RESULTS: Mean PWV and late loss were 1613 ± 371 cm s(-1), 0.10 ± 0.51 mm in the patients without diabetes and 1758 ± 404 cm s(-1), 0.16 ± 0.52 mm in the patients with diabetes, respectively. There was no significant relation between PWV and late loss in the patients with diabetes (correlation coefficient = 0.168; p=0.083). However, there was negative relation between PWV and late loss in the patients without diabetes (correlation coefficient = -0.185; p=0.032).
CONCLUSION: Increased arterial stiffness is favorable for late loss of the patients without diabetes undergoing PCI. However, this is not prognostic factor for the patients with diabetes.
