| LVEF ≤50% at 4 months (n=867) | LVEF >50% at 4 months (n=18) | P value | |
| Age (SD) | 60.57 (9.29) | 60.81 (8.02) | 0.915 |
| BMI (SD) | 27.43 (4.71) | 27.93 (3.91) | 0.654 |
| Medical therapy vs CABG (%) | 449 (51.8) | 6 (33.3) | 0.189 |
| Male gender (%) | 755 (87.1) | 13 (72.2) | 0.136 |
| Diabetes (%) | 356 (41.1) | 12 (66.7) | 0.052 |
| CRT=Yes (%) | 57 (6.6) | 3 (16.7) | 0.117 |
| OMT | 567 (65.4) | 12 (66.7) | 1 |
| ICD | 22 (2.5) | 0 (0.0) | 1 |
Data presented as mean (SD) for continuous variables and number (percentage) for categorical variables. Patients with and without recovered LVEF at 4 months were compared using t-test for continuous variables and χ2 test for categorical variables.
Medical therapy versus CABG refers to patients randomised to medical therapy alone or to CABG plus medical therapy. OMT refers to patient on OMT at 4 months follow-up.
BMI, body mass index; CABG, coronary artery bypass graft; CRT, cardiac resynchronisation therapy; ICD, permanent implanted cardiac defibrillator; LVEF, left ventricular ejection fraction; OMT, optimal medical therapy.
