ABSTRACT
BACKGROUND:
Long-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined.AIM:
To compare 10-year survival of isolated OPCAB versus CABG with CPB. MATERIAL ANDMETHODS:
Analysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital. Of 658 isolated CABG, 192 (29.2%) were OPCAB and 466 (79.9%) CPB. Propensity Score Matching (PSM) was performed to compare both groups. After PSM, two groups of 192 cases were obtained. Mortality data was obtained from the Chilean public identification service. Ten-year survival was calculated and compared with Kaplan-Meier and log-rank methods.RESULTS:
Follow-up data was obtained in all cases. No statistically significant differences were found when comparing 10-year survival between OPCAB versus CPB (78.6% and 80.2% respectively, p 0.720). There was also no statistical difference in cardiovascular death free survival (90.1% with CPB versus 89.1% OPCAB, p 0.737). Survival was comparable when analyzing subgroups with diabetes mellitus, left ventricular dysfunction or chronic kidney disease, among others.CONCLUSIONS:
In our series, OPBAB has a comparable 10-year survival with CABG with CPB.Key words
