Temporal changes in the outcomes of patients with diabetes mellitus undergoing percutaneous coronary intervention in the National Heart, Lung, and Blood Institute dynamic registry

Significant improvements over time in adverse events by 1 year were detected in patients with DM treated with oral agents. In insulin-treated diabetic patients, despite lower rates of repeat revascularization over time, death and MI following PCI have not significantly improved. These findings underscore the need for continued efforts at optimizing outcomes among patients with DM undergoing PCI, especially those requiring insulin treatment.
