          Abstract

          Background

          Angiotensin receptor neprilysin inhibitor (ARNi) therapy improves clinical outcomes in patients with heart failure and reduced left ventricular ejection fraction. However, ARNi therapy uptake remains modest, potentially in part due to perceived cost considerations of early transition from angiotensin converting enzyme inhibitor or angiotensin receptor blocker therapy.

          Methods

          We constructed a decision-analytic Markov model to assess cost-effectiveness of 3 different ARNi initiation strategies according to timing of initiation: (1) de novo, or immediate initiation at baseline, (2) Early or after 3 months, or (3) Late, or after 9 months. Initiation strategies were compared with (4) current care, with utilization of ARNi derived from a large observational database. Total costs, quality-adjusted life-years (QALYs), and the incremental cost-effectiveness ratio (ICER) were estimated over a 5-year time horizon in the base case analysis.

          Results

          Current care was associated with the lowest total cost (CAD$26,664) and accrued benefit (3.28 QALYs). The de novo strategy yielded an ICER of $34,727 per QALY gained, whereas Early and Late initiation strategies yielded a less favourable ICER per QALY gained of $35,871 and $40,234, respectively. The model was most sensitive to the cost of ARNi therapy.

          Conclusion

          A strategy of de novo ARNi initiation is economically attractive and becomes less favourable as the delay of initiation increases. Our results suggest that ARNi therapy should be initiated as soon as possible for patients with heart failure and reduced left ventricular ejection fraction.

          Résumé

          Contexte

          Le traitement par un antagoniste des récepteurs de l’angiotensine/inhibiteur de la néprilysine (ARNI) améliore les résultats cliniques chez les patients présentant une insuffisance cardiaque et une fraction d’éjection ventriculaire gauche réduite. L’adoption d’un tel traitement demeure toutefois modeste, peut-être en partie à cause des perceptions quant au coût associé à la substitution précoce d’un inhibiteur de l’enzyme de conversion de l’angiotensine ou d’un antagoniste des récepteurs de l’angiotensine.

          Méthodologie

          Nous avons mis au point un modèle de Markov appliqué à l’analyse décisionnelle afin d’évaluer le rapport coût-efficacité de trois stratégies d’instauration d’un traitement par un ARNI, selon le moment de la mise en route : 1) instauration de novo, c’est-à-dire instauration immédiate dès le départ; 2) instauration précoce (après trois mois); ou 3) instauration tardive (après neuf mois). Les stratégies d’instauration ont été comparées à 4) la norme de soins actuelle, l’utilisation des ARNI étant dérivée d’une importante base de données observationnelles. Dans l’analyse du scénario de référence, les coûts totaux, les années de vie pondérées par la qualité (QALY pour quality-adjusted life-years) et le rapport coût-efficacité différentiel (RCED) ont été estimés sur une période de cinq ans.

          Résultats

          La norme de soins actuelle était associée au coût le plus faible (26 664 $CAD) et à un bienfait cumulé (3,28 QALY). La stratégie de novo a donné lieu à un RCED de 34 727 $ par QALY gagnée, tandis que les RCED des stratégies d’instauration précoce et tardive étaient moins favorables et s’établissaient respectivement à 35 871 $ et à 40 234 $. Le modèle s’est révélé plus sensible au coût du traitement par un ARNI.

          Conclusion

          La mise en route d’un traitement par un ARNI de novo est attrayante sur le plan financier, et devient de moins en moins intéressante à mesure que le temps passe. Nos résultats indiquent qu’il faudrait instaurer le traitement par un ARNI le plus rapidement possible chez les patients présentant une insuffisance cardiaque et une fraction d’éjection ventriculaire gauche réduite.

            Dapagliflozin in Patients with Heart Failure and Reduced Ejection Fraction

            In patients with type 2 diabetes, inhibitors of sodium-glucose cotransporter 2 (SGLT2) reduce the risk of a first hospitalization for heart failure, possibly through glucose-independent mechanisms. More data are needed regarding the effects of SGLT2 inhibitors in patients with established heart failure and a reduced ejection fraction, regardless of the presence or absence of type 2 diabetes.

              Angiotensin–Neprilysin Inhibition versus Enalapril in Heart Failure

              We compared the angiotensin receptor-neprilysin inhibitor LCZ696 with enalapril in patients who had heart failure with a reduced ejection fraction. In previous studies, enalapril improved survival in such patients. In this double-blind trial, we randomly assigned 8442 patients with class II, III, or IV heart failure and an ejection fraction of 40% or less to receive either LCZ696 (at a dose of 200 mg twice daily) or enalapril (at a dose of 10 mg twice daily), in addition to recommended therapy. The primary outcome was a composite of death from cardiovascular causes or hospitalization for heart failure, but the trial was designed to detect a difference in the rates of death from cardiovascular causes. The trial was stopped early, according to prespecified rules, after a median follow-up of 27 months, because the boundary for an overwhelming benefit with LCZ696 had been crossed. At the time of study closure, the primary outcome had occurred in 914 patients (21.8%) in the LCZ696 group and 1117 patients (26.5%) in the enalapril group (hazard ratio in the LCZ696 group, 0.80; 95% confidence interval [CI], 0.73 to 0.87; P<0.001). A total of 711 patients (17.0%) receiving LCZ696 and 835 patients (19.8%) receiving enalapril died (hazard ratio for death from any cause, 0.84; 95% CI, 0.76 to 0.93; P<0.001); of these patients, 558 (13.3%) and 693 (16.5%), respectively, died from cardiovascular causes (hazard ratio, 0.80; 95% CI, 0.71 to 0.89; P<0.001). As compared with enalapril, LCZ696 also reduced the risk of hospitalization for heart failure by 21% (P<0.001) and decreased the symptoms and physical limitations of heart failure (P=0.001). The LCZ696 group had higher proportions of patients with hypotension and nonserious angioedema but lower proportions with renal impairment, hyperkalemia, and cough than the enalapril group. LCZ696 was superior to enalapril in reducing the risks of death and of hospitalization for heart failure. (Funded by Novartis; PARADIGM-HF ClinicalTrials.gov number, NCT01035255.).
