Prognostic Value of Serial Galectin-3 Measurements in Patients With Acute Heart Failure

BackgroundSeveral clinical studies have evaluated the association between galectin‐3 levels and outcome in patients with heart failure (HF). However, little is known about the predictive value of repeated galectin‐3 measurements. This study evaluates the prognostic value of repeated time‐dependent galectin‐3 measurements in acute HF patients. Methods and ResultsIn the TRIUMPH (Translational Initiative on Unique and Novel Strategies for Management of Patients with Heart Failure) clinical cohort study, 496 acute HF patients were enrolled in 14 hospitals in The Netherlands, between 2009 and 2014. Repeated blood samples (7) were drawn during 1‐year follow‐up. Associations between repeated biomarker measurements and the primary end point were assessed using a joint model. Median age was 74 years and 37% were women. The primary end point, composite of all‐cause mortality and HF rehospitalization, was reached in 188 patients (40%), during a median follow‐up of 325 days (interquartile range 85–401). The median ba...
