Background: Insulin resistance (IR) is known to be a risk factor for coronary artery disease (CAD). We aimed to evaluate the impact of IR on 1-year clinical outcomes in non-diabetic CAD patients who underwent percutaneous coronary intervention (PCI) with drug-eluting stents (DESs). Methods and results: A total of 229 consecutive non-diabetic CAD patients treated with DESs were enrolled. Study population was divided into IR group [homeostasis model assessment (HOMA) index ≥ 2.5, n= 54] and non-IR group (HOMA index < 2.5, n= 175). Baseline clinical and procedural characteristics were similar between the groups except higher incidence of high-sensitivity C-reactive protein and lower incidence of multivessel disease as the target vessel in the non-IR group. There was a trend toward longer restenosis lesion length in the IR group at 6 months angiographic follow up but composite major clinical outcomes up to 1 year were similar between the two groups. Conclusions: Despite worse trend in angiographic outcomes in the IR group (HOMA index ≥ 2.5), it was not translated into worse 1-year major clinical outcomes following PCI with DESs as compared to the non-IR group.
