|---|---|---|---|---|---|
| Septal Systolic Strain | Septal Diastolic SR | Disarray | Interstitial Fibrosis | SICAD | |
| RT | −0.29* | 0.27* | −0.26* | −0.37* | −0.21* |
| DT | −0.56* | 0.48* | −0.74* | −0.77* | −0.44* |
| TPT | −0.25* | 0.13 | −0.52* | −0.42* | −0.34* |
| THR | −0.07 | 0.15 | −0.07 | 0.05 | 0.09 |
| +dT/dt | −0.55* | 0.48* | −0.67* | −0.75* | −0.41* |
| −dT/dt | −0.57* | 0.44* | −0.70* | −0.76* | −0.40* |
SR indicates strain rate; SICAD, small intramural coronary arteriole dysplasia; DT, developed tension; RT, resting tension; TPT, time to peak tension; THR, time to half relaxation; +dT/dt indicates maximum rate of tension rise; –dT/dt, maximum rate of tension fall.
