| Case (n=228) | Control (n=214) | P Value | |
|---|---|---|---|
| LVEF ≥50% (n=442) | |||
| LVIDD, mm | 47.8±8.7 | 47.3±6.5 | 0.5 |
| LVIDD/BSA, mm/m2 | 24.6±4.6 | 24.3±3.7 | 0.4 |
| Moderate or severe LV dilatation | 9 (3.9%) | 4 (1.9%) | 0.2 |
| Severe LV dilatation | 2 (1%) | 0 (0%) | 0.2 |
| Case (n=181) | Control (n=105) | P value | |
|---|---|---|---|
| LVEF <50% (n=286) | |||
| LVIDD, mm | 57.9±9.7 | 54.4±8.2 | <0.01 |

BSA indicates body surface area; LV, left ventricular; LVEF, left ventricular ejection fraction; LVIDD, left ventricular internal dimension in diastole.
