Abstract:
ObjectiveTo study the effect of different renal functions on the prognosis of elderly patients with coronary neart disease (CHD). MethodsAll 383 patients with CHD were divided into elderly group and non-elderly group. Then patients in the elderly group were assigned to 4 groups according to the quartile of the estimated glomerular filtration rate (eGFR): GFR1 group (eGFR:1.73 m-2). All patients were followed up for 2 years, and the cumulative death rate of cardiovascular diseases and the relative risk for cardiovascular death were analyzed. Results(1)The cumulative death rate of cardiovascular diseases in elderly group was higher than that in non-elderly group (9.4vs. 1.3%, P=0. 019). (2)The cumulative death rate of cardiovascular diseases in GFR1,GFR2,GFR3 group were 6.8% ,6.3% ,4.6%, respectively, and there were no statistical differences among the three groups (P>0. 05). The cumulative death rate of cardiovascular diseases was 19.4% in GFR4 group, which was higher than that in other three groups (19.4% vs. 6.8%, P=0.038;19.4% vs. 6.3%, P=0.025 ;19.4% vs. 4.6%, P=0.009) . (3)Multivariate regression analysis revealed that eGFR was an independent prognosis factor for elderly patients with CHD, and the hazard ratio for cardiovascular death was 0. 965(95% CI: 0. 946～0. 985, P=0. 001). ConclusionseGFR is an important predictor for cardiovascular death in elderly patients with CHD.
