Abstract Aims ARIADNE aimed to assess the association between effects of sacubitril/valsartan and no sacubitril/valsartan treatment and clinical characteristics, functional capacity, and clinical outcomes (cause‐specific mortality and hospitalizations) in outpatients with heart failure (HF) with reduced ejection fraction (HFrEF). Methods ARIADNE was a prospective European registry of 9069 patients with HFrEF treated by office‐based cardiologists or selected primary care physicians. Of the 8787 eligible for analysis, 4173 patients were on conventional HF treatment (non‐S/V group), whereas 4614 patients were either on sacubitril/valsartan treatment at enrolment or started sacubitril/valsartan within 1 month of enrolment (S/V group). We also generated a restricted analysis set (rS/V) including only those 2108 patients who started sacubitril/valsartan treatment within the month prior to or after enrolment. Results At the baseline, average age of patients enrolled in the study was 68 years, and 23.9% (2099/8787) were female. At the baseline, the proportions of patients with New York Heart Association (NYHA) Class III symptoms were 30.9 (1288/4173), 42.8 (1974/4614), and 48.2% (1015/2108), in non‐S/V, S/V, and rS/V groups, respectively. After 12 months of treatment, the proportion of patients with NYHA Class III at baseline who improved to Class II was 32.0% (290/907) in the non‐S/V group vs. 46.3% (648/1399) in S/V group and 48.7% (349/717) in rS/V group. The overall mortality rate was 5.0 per 100 patient‐years. Rates of HF hospitalizations were high (20.9, 20.3, and 21.2 per 100 patient‐years in the non‐S/V, S/V, and rS/V groups, respectively). Emergency room visits without hospitalization occurred in 3.9, 3.2, and 3.9% of patients in the non‐S/V, S/V, and rS/V groups, respectively. Conclusions This large HFrEF European registry provides a contemporary outcome profile of outpatients with HFrEF treated with or without sacubitril/valsartan. In a real‐world setting, sacubitril/valsartan was associated with an improvement of symptoms in patients with HFrEF compared with the conventional HFrEF treatment.
