Comparative Study on Early and Long-term Outcomes Between On-pump and Off-pump Coronary Artery Bypass Grafting in Elder Female Patients / 中国循环杂志

ABSTRACT

Objective: To compare the early and long-term outcomes between on-pump and off-pump coronary artery bypass grafting (CABG) in elder female patients. Methods: A total of 763 female patients elder than 65 years of age received isolated CABG in our hospital from 1999-01 to 2008-12 were retrospectively studied. The patients were divided into 2 groups according to operational method: On-pump group,n=331 and Off-pump group,n=432. The mortality at 30 days post-operation, in-hospital clinical indexes and long term mortality with MACCE as all cause death, myocardial infarction (MI), stroke and repeated revascularization were compared between 2 groups. Results: Compared with On-pump group, the patients in Off-pump group had the elder age (P24h mechanical ventilation (P Conclusion: Off-pump CABG would reduce the mortality at 30 days post-operation, have less application of blood products, shorter post-operative mechanical ventilation, less early post-operative renal failure, pulmonary complications and re-exploration for bleeding. While it could not reduce the long-term mortality and MACCE occurrence.
