Table 2 Clinical characteristics, left ventricular function and cardiopulmonary capacity 7 days and 3 months after initiation of cardiac resynchronisation therapy.
| Characteristics | Optimal LV lead position (n = 25) | Non‐optimal LV lead position (n = 22) | p Value |
|---|---|---|---|
| NYHA functional class at 3 months | 2.0 (0.4) | 2.2 (0.6) | 0.041 |
| LVEF at 7 days (%) | 38 (7) | 34 (6) | 0.027 |
| LVGS at 7 days (%) | 15.1 (1.5) | 13.1 (1.7) | 0.009 |
| LVEF at 3 months (%) | 40 (7) | 35 (6) | 0.026 |
| LVGS at 3 months (%) | 15.4 (1.7) | 14.0 (2.0) | 0.008 |
| Vo2max at 3 months (ml/kg/min) | 16.2 (1.8) | 15.1 (2.1) | 0.156 |
Results are shown as mean (SD),
LVEF, left ventricular ejection fraction; LVGS, left ventricular global strain; NYHA, New York Heart Association; Vo2max, oxygen consumption at peak exercise.
