Abstract

Background: Renal dysfunction is associated with increased cardiovascular-related mortality, but its impact on outcome of out-of-hospital cardiac arrest (OHCA) remains unclear. We assessed whether post-OHCA outcome correlated with renal function early after OHCA. Methods and Results: Of the 16,452 registered patients in the SOS-KANTO 2012 Study, 5,112 cardiogenic OHCA adults with creatinine measurement (mean age, 72 years; male, 64%) were examined. First-obtained creatinine was used to assess eGFR. Associations between eGFR groups, ≥60 (n=997), 45–59 (n=1,311), 30–44 (n=1,441), and <30 mL/min/1.73 m2 (n=1,363), and 3-month survival and neurological outcomes were examined. Favorable neurological outcome was defined as cerebral performance categories 1 or 2. Survival rate (15.1%, 9.7%, 3.9%, and 2.9%; P<0.001) and proportion of favorable neurological outcome (12.3%, 7.4%, 2.6%, and 2.2%; P<0.001) were determined for eGFR groups ≥60, 45–59, 30–44, and <30 mL/min/1.73 m2, respectively. The survival rate decreased with eGFR (<60 mL/min/1.73 m2), and survival adjusted OR were 0.74 (95% CI: 0.54–1.03), 0.42 (95% CI: 0.28–0.62), and 0.43 (95% CI: 0.28–0.68) for eGFR 45–59, 30–44, and <30 mL/min/1.73 m2, respectively. The adjusted OR for favorable neurological outcome also decreased with eGFR: 0.74 (95% CI: 0.52–1.06), 0.40 (95% CI: 0.25–0.64), and 0.48 (95% CI: 0.29–0.81), respectively. Conclusions: An independent and graded association was observed between decreased eGFR and 3-month survival and proportion of favorable neurological outcome in cardiogenic OHCA patients.
