OUTCOMES OF OFF-PUMP VERSUS ON-PUMP CORONARY ARTERY BYPASS GRAFTING FOR ISCHEMIC HEART DISEASE IN PATIENTS OVER SEVENTY YEARS OF AGE

Abstract

Objective: To evaluate the perioperative characteristics and short term surgical outcomes of off-pump versus onpump CABG in elderly patients above the age of 70 years with ischemic heart disease.
Study Design: Descriptive cross-sectional study
Place & Duration of Study: This study was conducted at Army Cardiac Centre Lahore from January 2014 to
December 2015.
Material and Methods: A total of 129 patients according to inclusion criteria above 70 years of age were included
in the study. Patients with combined procedures (CABG with valve repair/ replacement) were excluded from the
study. Operative risk of all patients was assessed as per the European System for Cardiac Operative Risk
Evaluation (EuroSCORE).
Results: There were 53 patients in the OPCAB group and 76 patients in the CCAB group. The OPCAB group had
6 (11.3%) females and 47 (88.6%) males whereas in CCAB group there were 7 (9.2%) females and 69 (90.7%) males.
IABP was used only in CCAB group 12 (15.8%). As regards short term outcomes the OPCAB group had mean
extubation time of 228 ± 188.80 min as compared to CCAB group with a mean extubation time of 395.1 ± 489.7
min p value 0.001. Mean length of stay observed in OPCAB group was shorter 3.65 ± 2.63 days against CCAB
group 6.5 ± 6.9 days p value 0.01.
Conclusion: Off-pump (OPCAB) coronary artery bypass was associated with reduced adverse events compared
with on-pump (CCAB) coronary artery bypass in patients aged >70 years with a trend towards better early
survival
