Echocardigraphic measurements
| Variables | |
|---|---|
| Left ventricular ejection fraction (%) | 67 ± 7 |
| Left ventricular end diastolic volume (ml) | 68 ± 19 |
| Indexed Left ventricular end diastolic volume (ml/m2) | 34 ± 9 |
| Left atrial volume (ml) | 83.5 ± 23.7 |
| Indexed-left atrial volume (ml/m2) | 40.6 ± 11.5 |
| Change in left atrial volume (ml/year) | 3.9 ± 17.6 |
| Indexed-change in left atrial volume (ml/year/m2) | 1.9 ± 8.5 |
| Mitral inflow peak diastolic E velocity (cm/sec) | 85.0 ± 23.1 |
| Mitral inflow peak diastolic A velocity (cm/sec) | 41.3 ± 13.5 |
| Mitral valve inflow E/A | 2.3 ± 1.1 |
| Peak diastolic E velocity of lateral mitral annulus | 13.8 ± 3.7 |
| E/E' | 6.8 ± 3.3 |
E = diastolic early filling. A = diastolic atrial contraction. E/A = ratio of peak E velocity to A velocity of mitral inflow. E/E' = ratio of peak E mitral inflow velocity of peak E velocity of lateral mitral annulus. Data are mean ± SD. n = 50 except change in left atrial volume (n = 40).
