Abstract

Objectives This study sought to investigate the relationship between tubular damage and worsening renal function (WRF) in chronic heart failure (HF)

Background WRF is associated with poor outcome in chronic HF. It is unclear whether urinary tubular markers may identify patients at risk for WRF.

Methods In 2,011 patients with chronic HF, we evaluated the ability of urinary tubular markers (N-acetyl-beta-D-glucosaminidase (NAG), kidney injury molecule (KIM)-1, and neutrophil gelatinase-associated lipocalin (NGAL) to predict WRF. Finally, we assessed the prognostic importance of WRF.

Results A total of 290 patients (14.4%) experienced WRF during follow-up, and WRF was a strong and independent predictor of all-cause mortality and HF hospitalizations (hazard ratio [HR]: 2.87; 95% CI: 2.40 to 3.43; p <0.001). Patients with WRF had lower baseline glomerular filtration rate and higher KIM-1, NAG, and NGAL levels. In a multivariableadjusted model, KIM-1 was the strongest independent predictor of WRF (HR: 1.23; 95% CI: 1.09 to 1.39 per log increase; p = 0.001).

Conclusions WRF was associated with strongly impaired outcome in patients with chronic HF. Increased level of urinary KIM-1 was the strongest independent predictor of WRF and could therefore be used to identify patients at risk for WRF and poor clinical outcome.
