Contemporary Outcomes of Coronary Artery Bypass Grafting Among Patients With Insulin-Treated and Non-Insulin-Treated Diabetes.

Background: More than 40% of patients undergoing coronary artery bypass grafting (CABG) have diabetes. However, it is unknown how insulin treatment status influences cardiac surgical outcomes among patients with diabetes.

Methods: All isolated CABG, CABG plus aortic valve replacement or plus mitral valve repair/replacement procedures performed in 2012 were extracted from the California CABG Outcomes Reporting Program database.

Intraoperative conversion from off-pump to on-pump coronary artery bypass is associated with increased 30-day hospital readmission.

Background: We evaluated the impact of intraoperative conversion from off-pump coronary artery bypass graft surgery (OPCAB) to conventional coronary artery bypass graft surgery (CABG) with cardiopulmonary bypass (CCB) on rates of postoperative 30-day hospital readmissions.

Methods: Using data from the California CABG outcomes reporting program, postoperative 30-day hospital readmissions were compared among CCB, OPCAB, and intraoperative conversions from OPCAB to CCB (IOC) for isolated CABG operations. A multivariable logistic regression model with inverse propensity for OPCAB weighting was used to compute risk-adjusted readmission rates.

Coronary artery bypass operations for elderly patients in California, 2003 to 2008.

Background: Coronary artery bypass grafting (CABG) is no longer rare for elderly patients. This study evaluates operative mortality and the effects of off-pump CABG (OPCAB) on mortality for elderly Californians between 2003 and 2008.

Methods: All isolated CABGs in California for 2003 to 2008 were classified into cohorts by age: (1) younger than 75, (2) 75 to 84, and (3) 85 or older.
