We investigated the effect of beta-blockers according to LVEF in double-blind, randomised, placebo-controlled trials. Methods and Results: Individual patient data meta-analysis of eleven trials, stratified by baseline LVEF and heart rhythm (Clinical trials.gov:NCT0083244; PROSPERO:CRD42014010012). Primary outcomes were all-cause mortality and cardiovascular death over 1.3 years median follow-up, with an intention-to-treat analysis. For 14,262 patients in sinus rhythm, median LVEF was 27\% (interquartile range 21-33\%), including 575 patients with LVEF 40-49\% and 244 ≥50\%. Beta-blockers reduced all-cause and cardiovascular mortality compared to placebo in sinus rhythm, an effect that was consistent across LVEF strata, except for those in the small subgroup with LVEF ≥50\%. For LVEF 40- 49\%, death occurred in 21/292 [7.2\%] randomised to beta-blockers compared to 35/283 [12.4\%] with placebo; adjusted hazard ratio (HR) 0.59 (95\% CI 0.34-1.03). Cardiovascular death occurred in 13/292 [4.5\%] with beta-blockers and 26/283 [9.2\%] with placebo; adjusted HR 0.48 (95\% CI 0.24-0.97). Over a median of 1.0 years following randomisation, LVEF increased with beta-blockers in all groups in sinus rhythm except LVEF ≥50\% (n=4,601). For patients in atrial fibrillation at baseline (n=3,050), beta-blockers increased LVEF when}, doi = {10.1093/eurheartj/ehx564}, eissn = {1522-9645}, issn = {0195-668X}, issue = {1}, journal = {European heart journal}, pages = {26-35}, publicationstatus = {Published}, publisher = {Oxford University Press}, url = {https://hull-repository.worktribe.com/output/454868}, volume = {39}, keyword = {Health and Health Inequalities, Heart failure, Ejection fraction, Beta-blockers, Mortality, Sinus rhythm, Atrial fibrillation}, year = {2018}, author = {Cleland, John G.F. and Bunting, Karina V. and Flather, M. and Altman, Douglas G. and Holmes, Jane and Coats, Andrew J.S. and Manzano, Luis and McMurray, John J.V. and Ruschitzka, Frank and van Veldhuisen, Dirk J. and Von Lueder, Thomas G. and Böhm, Michael and Andersson, Bert and Kjekshus, John and Packer, Milton and Rigby, Alan S. and Rosano, Giuseppe and Wedel, Hans and Hjalmarson, Åke and Wikstrand, John and Kotecha, Dipak and Beta-blockers in Heart Failure Collaborative Group,} }
