In-Hospital Outcomes of Percutaneous Coronary Intervention in Diabetics

ABSTRACTBackgroundThere are few available reports in the literature assessing in-hospital outcomes of diabetic patients currently undergoing percutaneous coronary intervention (PCI). This article aimed to assess the acute post-PCI outcomes of a large series of diabetic and non-diabetic patients treated consecutively.MethodsFrom August 2006 to February 2012, 6,011 patients were submitted to PCI and included in the registry of the Hospital Bandeirantes. The techniques and devices for the procedure were chosen by the surgeons. Clinical outcomes were registered at the time of hospital discharge.ResultsDiabetic patients were older and more frequently females, with a higher prevalence of comorbidities and risk factors for coronary artery disease, except for smoking. However, most of the characteristics related to lesion complexity did not differ between groups. In diabetics, the number of treated vessels (1.6±0.8 vs. 1.4±0.7; P < 0.01) was higher, and the use of smaller stents (2.9±0.5mm vs. 3±0.5mm; P < 0.01) was more frequent. A procedural success rate of 95.5% was achieved in both groups. In-hospital outcomes did not differ in the incidence of major adverse cardiac and cerebrovascular events (3.3% vs. 2.8%; P=0.79), death (1% vs. 1.1%; P=0.90), acute myocardial infarction (2% vs. 2.4%; P=0.35), stroke (0.1% in both groups), and emergency revascularisation (0.3% in both groups). Arterial hypertension was the variable that best explained the occurrence of major adverse cardiac and cerebrovascular events [odds ratio (OR): 2.68, 95% confidence interval (95% CI): 1.13–6.38; P=0.026).ConclusionsDiabetes mellitus adds more clinical complexity to PCI but has no significant impact on in-hospital outcomes
