Impact Of Insulin Treated Diabetes Mellitus On 1 Year Outcomes After Contemporary Pci

Background: Insulin treated diabetes mellitus (ITDM) is associated with more extensive atherosclerotic disease and worse cardiovascular prognosis compared to non-ITDM patients. Hypothesis: We sought to examine 1-year outcomes in ITDM and non-ITDM patients compared to non-DM patients following contemporary percutaneous coronary intervention (PCI). Methods: We followed consecutive patients undergoing PCI at a large tertiary center from 2009-2016. Prospectively collected data were retrospectively examined. Patients were grouped based on DM and treatment status at baseline. 1-year outcomes were analyzed in a time to event manner and adjusted using multivariable Cox regression methods. Major adverse cardiovascular events (MACE) were defined as a composite of death, myocardial infarction (MI) or target vessel revascularization (TVR). Results: During the study period, 16,889 patients underwent PCI including 13.7% (n=2313) ITDM, 34.0% non-ITDM (n=5737) and 52.3% non-DM (n=8839) patients. ITDM and non-ITDM patient...
