Background and Aims: This study was performed to determine clinical relevance of perioperative B-type natriuretic peptide (BNP) in patients undergoing off-pump coronary artery bypass grafting. Methods: 145 consecutive patients undergoing off-pump coronary artery bypass grafting during 8-month period were enrolled in this study. The relationship between the plasma BNP and various clinical parameters was examined. Postoperatively their main clinical endpoints including requirement of mechanical ventilator support, length of intensive care unit stay and hospital stay was closely monitored. Results: Mean preoperative BNP levels were significantly higher in patients whose left ventricular ejection fraction was less than 0.50 (P<0.00083), and New York Heart Association class (III, IV) (P<0.02). The determinants of preoperative higher level of BNP can be related to the advanced age of the patients, r=0.387 (P<0.01) and left ventricular end diastolic diameter, r=0.200 (P<0.05). Postoperative 12-hour BNP correlated significantly with the duration of mechanical ventilation, rho=0.84 (P<0.05), and postoperative hospital stay for 10 days or more, rho=0.202 (P<0.05). Logistic regression analyses showed a significant association between 12-hour BNP and the requirement of mechanical ventilation, Wald=3.956 (P<0.049, 95% CI_1.023- 20.476). Conclusion: Plasma BNP concentration is a valuable biochemical marker, is easy to measure and can effectively predict postoperative outcome in off-pump coronary artery bypass grafting. Baseline BNP had strong correlation with the age and ventricular function of the patient. Postoperatively, elevated 12-hour BNP indicated prolonged ventilation and longer duration of hospital stay.

Pump Coronary Artery Bypass

The beneficial effects of intraaortic balloon pump (IABP) in coronary artery bypass graft surgery with cardiopulmonary bypass have been reported. However, whether preoperative insertion of IABP in high-risk off-pump coronary artery bypass grafting (OPCAB) has any beneficial effects remains to be established. We report our experience of preoperative insertion of IABP in OPCAB.

<p><b>Objectives:</b> Despite increasing recognition that off-pump coronary artery bypass surgery and sequential grafting strategy individually are associated with improved outcomes, concerns persist regarding the safety and efficacy of combining these 2 techniques. We compared in-hospital and midterm outcomes for off-pump multivessel sequential and conventional coronary artery bypass grafting.</p><p><b>Methods:</b> From September 1998 to September 2008, 689 consecutive patients received off-pump multivessel sequential coronary artery bypass grafting performed by a single surgeon. These patients were propensity matched to 689 patients who underwent off-pump coronary artery bypass grafting without sequential anastomoses. A retrospective analysis of prospectively collected perioperative data was performed. In addition, medical notes and charts of all the study patients were reviewed. The mean duration of follow-up was 5.1 � 2.0 years.</p><p><b>Results:</b> The major in-hospital clinical outcomes in the sequential and control groups were found to be similar. After adjusting for clinical covariates, sequential grafting was not an independent predictor of in-hospital adverse events (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.86-1.50; <i>P</i> = .31), medium-term mortality (hazard ratio [HR], 1.26; 95% CI, 1.06-1.32; <i>P</i> = .92), and readmission to hospital (HR, 1.12; 95% CI, 0.96-1.20; <i>P</i> = .80). Sequential grafting was an independent predictor of receiving more than 3 distal anastomoses (OR, 7.46; 95% CI, 4.27-11.45; <i>P</i> < .0001). Risk-adjusted survival was 89% for sequential grafting patients and 88% for conventional grafting patients (<i>P</i> = .96) during the medium-term follow-up.</p><p><b>Conclusion:</b> Our analysis confirms the short- and midterm safety and efficacy of off-pump sequential coronary artery bypass grafting.</p>
