Trajectories of renal biomarkers and new‐onset heart failure in the general population: Findings from the PREVEND study

Abstract

AimsRenal dysfunction is one of the most critical risk factors for developing heart failure (HF). However, the association between repeated measures of renal function and incident HF remains unclear. Therefore, this study investigated the longitudinal trajectories of urinary albumin excretion (UAE) and serum creatinine and their association with new‐onset HF and all‐cause mortality.Methods and resultsUsing group‐based trajectory analysis, we estimated trajectories of UAE and serum creatinine in 6881 participants from the Prevention of Renal and Vascular End‐stage Disease (PREVEND) study and their association with new‐onset HF and all‐cause death during the 11‐years of follow‐up. Most participants had stable low UAE or serum creatinine. Participants with persistently higher UAE or serum creatinine were older, more often men, and more often had comorbidities, such as diabetes, a previous myocardial infarction or dyslipidaemia. Participants with persistently high UAE had a higher risk of new‐onset HF or all‐cause mortality, whereas stable serum creatinine trajectories showed a linear association for new‐onset HF and no association with all‐cause mortality.ConclusionOur population‐based study identified different but often stable longitudinal patterns of UAE and serum creatinine. Patients with persistently worse renal function, such as higher UAE or serum creatinine, were at a higher risk of HF or mortality.
