Abstract:
Introduction: Although albuminuria evaluated with urinary albumin-to-creatinine ratio (UACR) was shown to be a prognostic marker in patients with heart failure, measurement of UACR needs special equipment. Urine dipstick test is a simple and convenient method which is available even in community-based health care. Hypothesis: We hypothesized that dipstick proteinuria might be a prognosticator in HFpEF. Methods: We assessed 738 discharged-alive patients in the PURSUIT-HFpEF registry. Patients received urine dipstick test, and were divided into 2 groups according to the absence or presence of proteinuria (proteinuria trace or more). The study endpoint was a composite of all-cause mortality and HF hospitalization. Results: Median age was 82 years and 410 patients were female. Four hundred thirty-four patients: proteinuria-(group 1); 304 patients: proteinuria+(group 2). Group 2 was more likely male with higher frequency of diabetes, previous myocardial infarction and chronic kidney disease, but less likely to take ACEIs than group 1. Higher blood pressure, NT-proBNP, creatinine, E/e’, TRPG, and LV mass index were observed in group 2 than group 1. The composite endpoint and HF hospitalization occurred more often in group 2 than group 1 (HR: 1.43, 95%CI: 1.09-1.87, log-rank P=0.009; HR: 1.57, 95%CI: 1.14-2.15, log-rank P=0.005, respectively); but all-cause mortality did not (HR: 1.40, 95%CI: 0.92-2.11, log-rank P=0.113). Multivariable Cox regression adjusting for NT-proBNP, eGFR and other major confounding factors showed that proteinuria was associated with the composite endpoint (HR: 1.42, 95% CI: 1.05-1.94, P=0.026), and HF hospitalization (HR: 1.51, 95%CI: 1.04-2.18, P=0.030), but not with all-cause mortality (HR: 1.51, 95%CI:0.94-2.43, P=0.092). Conclusions: Dipstick proteinuria may be a prognostic marker in patients with HFpEF. Evaluation of proteinuria by urine dipstick test may be a simple but useful method for risk stratification in HFpEF.
