Comparing short and long term survival of patients undergoing off pump coronary artery bypass graft with and without coronary endarterectomy.

BACKGROUND AND AIM

There is some controversy about survival of coronary endarterectomy (CE) patients, so the current study aims to compare short and long term survival of patients undergoing off pump coronary artery bypass graft (OPCAB) with and without coronary endarterectomy.

PATIENTS AND METHODS

we performed a retrospective analysis of data on patients undergoing OPCAB and CE between 2011 and 2012. Preoperative, perioperative and postoperative data collected from data bank. Follow-up information was obtained from telephone contact mean time 37.13±23.82months after surgery. Early and late outcomes were compared by univariate and Kaplan-Meier analysis.

RESULT

OPCAB was performed in 474 patients, which 69 of them had a CE. The mean long term survival was similar between OPCAB (56.28±0.61) and OPCAB+CE (55.54±1.3) groups (p=0.66). Multiple Cox regression shows that age, gender, BMI, EF and angina were significant predictors of mortality. Patients undergoing CE have a long term intensive care unit (ICU) stay (51.31±5.59 vs 37.23±0.88, P=0.015) and blood transfusion was higher in CE group (650.62±110 vs. 324.71±22, P=0.001).

CONCLUSION

The current study demonstrates that results of CE are acceptable with respect to short and long -term survival. Patients undergoing CE required long term ICU stay and higher blood transfusion.
