Echocardiographic Measurements Early and Late From CRT in Patients With a Systemic LV
| Variable | Pre‐CRT (n=39) | Early Follow‐Up (n=39) | P Valuea | Late Follow‐Up (n=25) | P Valueb |
|---|---|---|---|---|---|
| LAVI, mL/m2 | 47.0 (33.0–58.0) | 40.0 (30.0–55.0) | 0.081 | 37.0 (22.0–54.5) | 0.363 |
| RAVI, mL/m2 | 39.0 (26.0–55.0) | 32.0 (22.0–51.0) | 0.010 | 34.0 (26.5–62.0) | 0.486 |
| LVEF, % | 28.9±7.1 | 38.6±11.2 | <0.001 | 35.6±12.7 | 0.014 |
| LVEDD, mm | 63.2±10.2 | 60.7±9.7 | 0.052 | 60.3±11.5 | 0.111 |
| LVESD, mm | 51.7±10.5 | 48.1±11.6 | 0.043 | 48.0±13.4 | 0.190 |
| LVEDV, mL | 216±76 | 185±66 | 0.010 | 193±82 | 0.055 |
| LVESV, mL | 155±65 | 118±57 | 0.001 | 124±68 | 0.010 |
Values are mean±SD or median (interquartile range). CRT indicates cardiac resynchronization therapy; LAVI, left atrial volume index; LV, left ventricle; LVEDD, LV end‐diastolic diameter; LVEDV, LV end‐diastolic volume; LVEF, LV ejection fraction; LVESD, LV end‐systolic diameter; LVESV, LV end‐systolic volume; RAVI, right atrial volume index.
