Worsening renal function and outcome in heart failure patients with reduced and preserved ejection fraction and the impact of angiotensin receptor blocker treatment: data from the CHARM‐study programme

AIMS: We investigated the association between worsening renal function (WRF) that occurs during renin-angiotensin-aldosterone system inhibition initation and outcome in heart failure (HF) patients with preserved ejection fraction (HFPEF) and compared this with HF patients with reduced ejection fraction (HFREF). METHODS AND RESULTS: We examined changes in estimated glomerular filtration rate (GFR) and the relationship between WRF (defined as …
