Echocardiographic data comparing those with versus without LV dysfunction during follow-up
| Variable | No LV dysfunction (n=17) | LV dysfunction (n=40) | ||||
| Initial | Final | P value | Initial | Final | P value | |
| LVIDd (cm) | 3.8±0.4 | 3.9±0.6 | 0.999 | 4.6±0.7 | 5.5±1.2 | <0.001 |
| SF (%) | 33.8±6.3 | 33.4±5.3 | 0.843 | 25.0±8.8 | 13.7±7.1 | <0.001 |

E/A, ratio of mitral inflow velocity during early diastole/velocity to atrial contraction; LV, left ventricular; LVIDd, left ventricular internal diameter at end-diastole; SF, shortening fraction.
