Study Design
This retrospective, intention-to-treat, cohort study was conducted in compliance with federal regulations, the Declaration of Helsinki, and Institutional Review Board (IRB) standards. A national sample was gathered after a Request for Data Access application to the STS. Among 663 participating sites, the STS National Cardiac Database (version 2.52) was reviewed for risk factors and clinical outcomes of 42,477 consecutive, nonemergency, isolated, primary ONCAB or OPCAB cases performed at those
Preoperative Characteristics
Table 1 lists patient characteristics and risk factors for each combination of gender and surgery type within the population of 42,477 consecutive patients. The 11,785 women in the study were significantly older (67.0 versus 64.1, p < 0.001) and had more comorbidities and a higher STS predicted risk [21] of mortality (3.0%) than the 30,662 men (predicted risk 1.7%; p < 0.001). The 16,245 patients treated with OPCAB were older (65.6 versus 64.5 years, p < 0.001) than the 26,202 patients treated
Comment
This retrospective review of the STS National Adult Cardiac Database analyzed preoperative risk factors and postoperative outcomes for 42,477 consecutive patients who underwent nonemergency, isolated, primary CABG from January 1, 2004, through December 31, 2005. This data sample was limited to 63 institutions that were reasonably experienced in both off-pump and on-pump CABG and included consecutive cases performed since the introduction of a data field recording intraoperative conversion of
