  • *Mean (95% CIs) estimated using linear regression. Unadjusted: adjusted only for baseline LVESV or LVESVi, respectively. Minimally adjusted: adjusted additionally for QRS ≥150 ms and LBBB. Fully adjusted: adjusted additionally for age, gender, HF aetiology (ischaemic vs non-ischaemic), systolic blood pressure, diabetic status, serum creatinine, β-blocker usage, ACE inhibitor or ARB usage, aldosterone-antagonist usage and EF.

  • ARB, angiotensin receptor blocker; EF, ejection fraction; HF, heart failure; LBBB, left bundle-branch block; LVESV, left ventricular end-systolic volume.
