Associations between discharge heart rate and 1-year clinical outcomes in the entire cohort. (A) The primary outcome, which was defined as a composite outcome of all-cause death and HF rehospitalization; (B) all-cause death; (C) HF rehospitalization; (D) composite outcome of all-cause death and all-cause rehospitalization. The analysis used a Cox model with restricted cubic splines, corrected for age, sex, smoking status, medical history, LVEF, QRS duration, laboratory tests, NYHA classifications, SBP, and medication use at discharge, and the reference was the median of discharge heart rate (75 bpm). Solid lines represented HRs, and green light shaded areas represented 95% CI. Bpm: Beats per minute; CI: Confidence interval; HR: Hazard ratio; HF: Heart failure; HR: Hazard ratio; LVEF: Left ventricular ejection fraction; NYHA: New York Heart Association; SBP: Systolic blood pressure.
