Background: This study was conducted to explore the impact of renal dysfunction on short-term and mid-term outcomes in elderly patients.
Methods: Patients over 65 years of age receiving surgical ventricular restoration (SVR) were included in the study. They were stratified through estimated glomerular filtration rate (eGFR), with a cutoff point of 60 mL/min/1.73m2. Risk-adjusted analysis, including propensity score matching, was carried out to compare short-term and mid-term outcomes between the two groups of patients.
Results: From January 1999 to December 2015, a total of 280 elderly patients underwent SVR. Of the patients, 79 had eGFR lower than 60 mL/min/1.73m2 and were considered to have renal dysfunction. Mortality was higher in the renal dysfunction group than the normal renal function group, with marginal significance (adjusted P value = .06). The need for mechanical supports (adjusted P value = .04) was higher in the renal dysfunction group. Hemofiltration (adjusted
P value < .01) and requirements for transfusion (adjusted
P value = .03) were significantly higher in the renal dysfunction group than in the group with normal renal function. The presence of renal dysfunction was associated with higher risk of major adverse cerebro-cardiovascular events (MACCE) than normal renal function (HR = 2.34, 95% CI = 1.34 - 4.08, P = .003).
Conclusion: Compared to patients with normal renal function, elderly SVR patients with renal failure have a higher incidence of short-term mechanical support, mid-term mortality, and MACCE events.
