From: Diastolic wall strain: a simple marker of abnormal cardiac mechanics
| Â | Abnormal value | Correlation with DWS | ROC analysis | |
|---|---|---|---|---|
Strain parameter | R | P-value | C-statistic (95% CI) | |
Global longitudinal strain | < 12.5% | 0.61 | 0.0001 | 0.78 (0.61-0.95) |
Global circumferential strain | < 15% | 0.57 | 0.0003 | 0.79 (0.61-0.97) |
Global radial strain | < 35% | 0.73 | <0.0001 | 0.84 (0.71-0.97) |
