Impact of Sacubitril/Valsartan on the Long-Term Incidence of Ventricular Arrhythmias in Chronic Heart Failure Patients.

ABSTRACT: BACKGROUND:Sacubitril/valsartan decreased the risk of sudden cardiac death (SCD) in patients suffering from heart failure with reduced ejection fraction (HFrEF). However, long-term data are sparse. OBJECTIVE:The aim of the present study was to compare the incidence of life-threatening arrhythmias consisting of ventricular tachycardia and/or ventricular fibrillation before and after initiation of sacubitril/valsartan treatment. METHODS:Out of 12,000 patients with HFrEF from 2016-2018, 148 patients were newly prescribed sacubitril/valsartan, but the long-term data of only 127 patients were available and included in this study. RESULTS:Patients with an average age of 66.8 ± 12.1 had a median left ventricular ejection fraction (LVEF) of 25% (interquartile range (IQR) 5.00-45.00) and 30% (IQR 10.00-55.00, p < 0.0005) before and after sacubitril/valsartan treatment, respectively. Systolic blood pressure decreased from 127.93 ± 22.01 to 118.36 ± 20.55 mmHg (p = 0.0035) at 6 months of follow-up. However, in 59 patients with a long-term outcome of 12 months, ventricular arrhythmias persistently increased (ventricular fibrillation from 27.6 to 29.3%, ventricular tachycardia (VT) from 12% to 13.8%, and nonsustained VT from 26.6 to 33.3%). CONCLUSIONS:Sacubitril/valsartan does not reduce the risk of ventricular tachyarrhythmias in chronic HFrEF patients over 12 months of follow-up.

Project description:AimsOptimizing medical cardiac treatment for sleep apnoea (SA) in patients with chronic heart failure and reduced ejection fraction (HFrEF) is an expert Grade C recommendation based on six studies encompassing a total of 67 patients only. Whether sacubitril-valsartan (SV), a cornerstone of HFrEF medical treatment, impacts SA is unknown and requires evaluation.Methods and resultsThe ENTRESTO-SAS trial is a six-centre, prospective, open-label real-life cohort study (NCT02916160). Ambulatory patients eligible for SV (i.e. HFrEF adults who remain symptomatic despite optimal treatment) were evaluated before and after 3 months of SV (including nocturnal ventilatory polygraphy); 118 patients were final analysed [median age was 66 (IQ25-75 : 56-73) years, 81.4% male, 36.5% New York Heart Association III-IV, N-terminal pro-B-type natriuretic peptide level of 1564 (701-3376) ng/L, left ventricular ejection fraction of 30 (25-34)%, 60.7% ischaemic HFrEF, 97.5% initially treated with angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, 83.9% with beta-blockers, 64.4% with mineralocorticoid receptor antagonists, and 74.6% with diuretics]. Three groups were defined according to initial central/obstructive apnoea-hypopnoea indices (AHIs): G1 (n = 49, AHIcentral ≥ 5/h and AHIobstructive < 15/h); G2 (n = 27, AHIobstructive ≥ 15/h); and G3 (n = 42, AHIcentral < 5/h and AHIobstructive < 15/h). At 3 months, the AHI (main predefined outcome) decreased significantly by -7.10/h (IQ25-75 : -16.10 to 0.40; P < 0.001) in G1 + G2 without positive airway pressure treatment (45 patients, median initial AHI of 24.20 (IQ25-75 : 16.40-43.50)/h). Of these, 24.4% presented an AHI decrease ≥50% and 37.78% had a final AHI < 15/h (tendency for improvement from an initial value of 20%: P = 0.0574). For G1 patients (n = 37), AHI significantly decreased from a median of 22.90 (16.00-43.50)/h to 19.20 (12.70-31.10)/h (P = 0.002). For G2 patients (n = 8), AHI decreased from a median of 30.10 (26.40-47.60)/h to 22.75 (14.60-36.90)/h (statistically non-significant, P = 0.059).ConclusionsIn this real-life population, SV treatment for 3 months in SA patients is associated with a significant decrease in AHI. These results support the current guidelines that recommend first an optimization of the HFrEF treatment in patients with HFrEF and central SA. A potential positive airway pressure sparing effect merits further investigation.
