Indices of left ventricular function; results are mean (SD)
| Echo | LVEDD (cm) | 6.77 (1.17) |
| LVESD (cm) | 5.61 (1.38) | |
| Fractional shortening | 0.18 (0.09) | |
| RNVG | LVEF (%) | 27.0 (15.0) |
| CXR | CTR | 0.56 (0.06) |
CTR = cardiothoracic ratio; CXR = chest radiograph; LVEDD = left ventricular end diastolic dimension; LVEF = left ventricular ejection fraction; LVESD = left ventricular end systolic dimension; RNVG = radionuclide ventriculography.
