Biomarkers of renal dysfunction, endothelial dysfunction, and inflammation were associated with incident heart failure with reduced ejection fraction. By contrast, only natriuretic peptides and urinary albumin to creatinine ratio were associated with heart failure with preserved ejection fraction (HFpEF), a finding that highlights the need for future studies focused on identifying novel biomarkers of the risk of HFpEF, according to a study in JAMA Cardiology.
