Comparative StudyThe Bypass Angioplasty Revascularization in Type 1 and Type 2 Diabetes Study: 5-year follow-up of revascularization with percutaneous coronary intervention versus coronary artery bypass grafting in diabetic patients with multivessel disease.
The aim of the Bypass Angioplasty Revascularization in Type 1 and Type 2 Diabetes study was to assess percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) as treatments for multivessel coronary artery disease in diabetic patients. ⋯ In the Bypass Angioplasty Revascularization in Type 1 and Type 2 Diabetes study, diabetic patients with multivessel coronary artery disease had similar long-term mortality whether treated with CABG or PCI, the revascularization determined by the physician's choice. This was despite the frequent use of a strategy of selective revascularization in the PCI arm. Randomized trials comparing PCI and CABG specifically in diabetes, that is, Coronary Artery Revascularization in Diabetes and Future Revascularization Evaluation in Diabetes Mellitus: Optimal Management, will show whether drug-eluting stents further enhance PCI outcomes over the long term.

Permanent pacemaker implantation after isolated aortic valve replacement: incidence, risk factors and surgical technical aspects.
Conducting system defects are common in patients with aortic valve disease. Aortic valve replacement may result in further conduction abnormalities requiring permanent pacemaker implantation. The aim of our study was to identify the incidence and predictors for postoperative 30-day permanent pacemaker implantation in patients undergoing isolated aortic valve replacement, and the effect of an accurate surgical technique in order to prevent permanent pacemaker implantation. ⋯ Need of permanent pacemaker implantation after aortic valve replacement seems to be related more to preoperative advanced aortic valve disease rather than pre-existing conducting system abnormalities. An accurate surgical technique for aortic valve replacement probably helps to prevent further impairment of conducting system function requiring early postoperative permanent pacemaker implantation.

Postprocedural hyperglycemia in ST elevation myocardial infarction submitted to percutaneous coronary intervention: a prognostic indicator and a marker of metabolic derangement.
Hyperglycemia in acute coronary syndrome is associated with an increased risk of death in patients without previously known diabetes but the prognostic role of postrevascularization hyperglycemia in these patients is so far incompletely elucidated. ⋯ In ST elevation myocardial infarction patients without previously known diabetes submitted to percutaneous coronary intervention, glucose serum levels measured after mechanical revascularization were independent predictors of in-hospital mortality.
