Data are presented as mean (SD) for continuous variables and number (percentage) for categorical variables. Patients included and excluded from the analysis were compared using t-test for continuous variables and χ2 test for categorical variables.
STICH refers to all patients included in the STICH trial. Included refers to subgroup of STICH trial patients who had LVEF assessment during follow-up and were included in this study. Excluded refers to subgroup of STICH trial patients who did not have LVEF assessment during follow-up and were excluded from this study. Medical therapy versus CABG refers to patients randomised to medical therapy alone or to coronary artery bypass graft plus medical therapy.
BMI, body mass index; CABG, coronary artery bypass graft; CRT, cardiac resynchronisation therapy; ICD, permanent implanted cardiac defibrillator; LVEF, left ventricular ejection fraction; STICH, Surgical Treatment for Ischaemic Heart Failure.
