Don't blame the stents.

iabetes mellitus portends excessive adverse clinical outomes for coronary artery disease (CAD) patients, including hose undergoing percutaneous coronary intervention (PCI) 1–5). Causes for adverse outcomes in diabetic patients nclude more stent hyperplasia (3), smaller vessels, greater ascular inflammation, a higher thrombotic state, type of iabetic treatment (oral vs. insulin), and severe diffuse ascular disease promoted by more risk factors, with a arked increase in the relative adverse impact on outcome or each risk factor. Furthermore, the outcomes of diabetic atients with CAD indicate that eliminating ischemia aused by a finite number of focal stenoses is not sufficient. evascularization reduces angina as well as morbidity and ortality, particularly in high-risk patients. However, future vents are more often related to progressive CAD, often the esult of non-critical lesions observed during earlier angiogaphy (1).
