| SV index, mL/m2 | 35 ± 15 | 32 ± 12 | NS |
| Heart rate, bpm | 85 ± 18 | 81 ± 15 | NS |
| Cardiac index, L/min/m2 | 2.8 ± 0.9 | 2.5 ± 0.8 | NS |
| LV free wall mass index, g/m2 | 59 ± 15 | 62 ± 17 | NS |
| RV free wall mass index, g/m2 | 51 ± 29 | 56 ± 31 | NS |
Note
Data are mean ± standard deviation and were analyzed using repeated-measures analysis of variance with Bonferroni post hoc tests to correct for multiple measurements. All parameters are corrected for body surface area of the patients. LV: left ventricular; NS: not significant; RV: right ventricular; SV: stroke volume; EDV: end-diastolic volume.
