ABSTRACT
Objective To evaluate the postoperative prognosis of the modification of diet in renal disease formula (MDRD) in coronary artery bypass graft surgery (CABG) in hospital or 4 years after hospitalization. Methods Two hundred and seventy-two CABG patients were divided into 3 groups according to the levels of estimated glomerular filtration rate (eGFR) including 35 cases in eGFR < 60 ml/min group, 119 cases in 60 ≤ eGFR < 90 mL/min group and 118 cases in eGFR ≥90 ml/min group. The prognostic factors of CABG patients were analyzed by COX proportional hazards models. Kaplan-Meier survival analysis was used to compare survival curves among the three groups stratified by eGFR levels. The Log-rank statistic was used for comparing between groups. Results By multivariate COX regression adjustment for body mass index, smoking, hypertension, hyperlipaemia, diabetes mellitus, previous MI, perioperative PCI and etc. , the relative risk (RR) of the increasing age for cardiac events was 1.077(95% CI 1.002-1.158,P =0.044). RR of left ventricular ejection fraction (LVEF) was 0.005(95% CI 0.000-0.456,P =0.022). RR of eGFR was 0.968(95% CI 0.948-0.988,P =0.002). The survival rate in the first, second, third and fourth year were same in every group. The survival rate of group with eGFR < 60 ml/min, 60 ≤ eGFR < 90 ml/min and eGFR≥ 90 mL/min was 76.4%, 93.1%, and 96.6%. The survival rates among three groups were statistically significant. In the survival curve of 4 year follow-up after CABG, the survival rate of group with eGFR < 60 mL/min was lower than that of 60 ≤ eGFR < 90 ml/min group and eGFR ≥ 90 ml/min group. Conclusions The preoperative eGFR is an independent risk factor in evaluating cardiac events in hospital and after hospitalization. It has a higher prognosis value in patients undergoing CABG.
