Background: Studies investigating clinical outcomes of patients with or without endothelial disfunction (ED) treated with percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) using second generation drug eluting stents (DES) are lacking. Methods: We prospectively collected data from 109 patients undergoing PCI with second generation DES due to stable CAD between December 2014 and September 2016. ED was evaluated evaluating the flow mediated dilation (FMD) at the brachial artery level and defined by an FMD < 7 %. Primary outcome were major adverse cardiovascular events (MACE), secondary outcomes were target vessel failure (TVR), myocardial infarction (MI) and all-cause death. Results: Five-year follow-up was available in all patients. Median FMD didn't significantly differ between patients who experienced the outcome and those who didn't [no TVR vs. TVR: p = 0.358; no MI vs. MI: p = 0.157; no death vs. death: p = 0.355; no MACE vs. MACE: p = 0.805]. No association between ED and an increased risk for the primary outcome as well as for the secondary ones was evident [MACE: 17.0 % vs. 14.3 %, HR 0.87 (0.33-2.26), log rank p = 0.780; TVR: 9.4 % vs. 5.4 %, HR 0.53 (0.12-2.24), log rank p = 0.384; MI: 3.7 % vs. 8.9 %, HR 2.46 (0.47-12.76), log rank p = 0.265; death: 7.5 % vs. 3.6 %, HR 0.53 (0.09-2.90), log rank p = 0.458]. These findings were confirmed using a lower threshold of FMD to define ED and at one-year landmark analysis. Conclusions: ED is not associated with an increased risk of adverse events at long-term follow-up in a contemporary cohort of patients undergoing PCI with second generation DES.

Abstract

Background: Studies investigating clinical outcomes of patients with or without endothelial disfunction (ED) treated with percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) using second generation drug eluting stents (DES) are lacking. Methods: We prospectively collected data from 109 patients undergoing PCI with second generation DES due to stable CAD between December 2014 and September 2016. ED was evaluated evaluating the flow mediated dilation (FMD) at the brachial artery level and defined by an FMD < 7 %. Primary outcome were major adverse cardiovascular events (MACE), secondary outcomes were target vessel failure (TVR), myocardial infarction (MI) and all-cause death. Results: Five-year follow-up was available in all patients. Median FMD didn't significantly differ between patients who experienced the outcome and those who didn't [no TVR vs. TVR: p = 0.358; no MI vs. MI: p = 0.157; no death vs. death: p = 0.355; no MACE vs. MACE: p = 0.805]. No association between ED and an increased risk for the primary outcome as well as for the secondary ones was evident [MACE: 17.0 % vs. 14.3 %, HR 0.87 (0.33-2.26), log rank p = 0.780; TVR: 9.4 % vs. 5.4 %, HR 0.53 (0.12-2.24), log rank p = 0.384; MI: 3.7 % vs. 8.9 %, HR 2.46 (0.47-12.76), log rank p = 0.265; death: 7.5 % vs. 3.6 %, HR 0.53 (0.09-2.90), log rank p = 0.458]. These findings were confirmed using a lower threshold of FMD to define ED and at one-year landmark analysis. Conclusions: ED is not associated with an increased risk of adverse events at long-term follow-up in a contemporary cohort of patients undergoing PCI with second generation DES.
