Abstract

OBJECTIVES This study sought to estimate and compare the aggregate treatment benefit of pharmacological therapy for heart failure (HF) with reduced ejection fraction. BACKGROUND The estimated treatment effects of various combinations of contemporary HF medical therapies are not well characterized. METHODS We performed a systematic network meta-analysis, using MEDLINE/EMBASE and the Cochrane Central Register of Controlled Trials for randomized controlled trials published between January 1987 and January 2020. We included angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers (BB), mineralocorticoid receptor antagonists (MRAs), digoxin, hydralazine-isosorbide dinitrate, ivabradine, angiotensin receptor-neprilysin inhibitors (ARNi), sodium glucose cotransporter-2 inhibitors (SGLT2i), vericiguat, and omecamtiv-mecarbil. The primary outcome was all-cause death. We estimated the life-years gained in 2 HF populations (BIOSTAT-CHF [BIOlogy Study to TAilored Treatment in Chronic Heart Failure] and ASIAN-HF [Asian Sudden Cardiac Death in Heart Failure Registry]). RESULTS We identified 75 relevant trials representing 95,444 participants. A combination of ARNi, BB, MRA, and SGLT2i was most effective in reducing all-cause death (HR: 0.39; 95% CI: 0.31-0.49); followed by ARNi, BB, MRA, and vericiguat (HR: 0.41; 95% CI: 0.32-0.53); and ARNi, BB, and MRA (HR: 0.44; 95% CI: 0.36-0.54). Results were similar for the composite outcome of cardiovascular death or first hospitalization for HF (HR: 0.36; 95% CI: 0.29-0.46 for ARNi, BB, MRA, and SGLT2i; HR: 0.44; 95% CI: 0.35-0.56 for ARNi, BB, MRA, and omecamtiv-mecarbil; and HR: 0.43; 95% CI: 0.34-0.55 for ARNi, BB, MRA, and vericiguat). The estimated additional number of life-years gained for a 70-year-old patient on ARNi, BB, MRA, and SGLT2i was 5.0 years (2.5-7.5 years) compared with no treatment in secondary analyses. CONCLUSIONS In patients with HF with reduced ejection fraction, the estimated aggregate benefit is greatest for a combination of ARNi, BB, MRA, and SGLT2i.
