Heart failure in Europe: Guideline-directed medical therapy use and decision making in chronic and acute, pre-existing and de novo, heart failure with reduced, mildly reduced, and preserved ejection fraction - the ESC EORP Heart Failure III Registry

Aims We analysed baseline characteristics and guideline-directed medical therapy (GDMT) use and decisions in theEuropean Society of Cardiology (ESC) Heart Failure (HF) III Registry. Methods and results Between1November 2018and31December 2020,10162 patients with acute HF (AHF, 39%, age 70 [62-79],36% women) or outpatient visit for HF (61%, age 66 [58-75], 33% women), with HF with reduced (HFrEF, 57%),mildly reduced (HFmrEF,17%) or preserved (HFpEF, 26%) ejection fraction were enrolled from 220 centres in 41European or ESC-affiliated countries. With AHF, 97% were hospitalized, 2.2% received intravenous treatment in theemergency department, and 0.9% received intravenous treatment in an outpatient clinic. AHF was seen by most bya general cardiologist (51%) and outpatient HF most by a HF specialist (48%). A majority had been hospitalized forHF before, but 26% of AHF and 6.1% of outpatient HF had de novo HF. Baseline use, initiation and discontinuation ofGDMT varied according to AHF versus outpatient HF, de novo versus pre-existing HF, and by ejection fraction. Afterthe AHF event or outpatient HF visit, use of any renin-angiotensin system inhibitor, angiotensin receptor-neprilysininhibitor, beta-blocker, mineralocorticoid receptor antagonist and loop diuretics was 89%, 29%, 92%, 78%, and 85%in HFrEF; 89%, 9.7%, 90%, 64%, and 81% in HFmrEF; and 77%, 3.1%, 80%, 48%, and 80% in HFpEF. ConclusionUse and initiation of GDMT was high in cardiology centres in Europe, compared to previous reports from cohortsand registries including more primary care and general medicine and regions more local or outside of Europe andESC-affiliated countries.....................................
