The mean segmental longitudinal, circumferential and radial peak-systolic strain (εps) in subjects with Churg–Strauss syndrome (CSS), granulomatosis with polyangiitis (Wegener’s) (WG), controls as well as with regard to the spatial distribution of late gadolinium enhancement (LGE) lesions
| Segmental εps | CSS (n = 11) | WG (n = 10) | Subendocardial LGE (n = 6) | Midwall LGE (n = 10) |
Subepicardial LGE (n = 8) | Controls (n = 21) |
|---|---|---|---|---|---|---|
| Longitudinal [%] | −20.2 ± 10.0* | −20.4 ± 9.6* | −11.8 ± 5.6* | −13.2 ± 5.5* | −19.7 ± 2.9 | −22.7 ± 5.1 |
| Circumferential [%] | −24.0 ± 7.0 | −23.5 ± 7.8 | −22.6 ± 3.1 | −16.6 ± 4.2* | −21.9 ± 2.8 | −23.6 ± 5.6 |
| Radial [%] | 30.5 ± 13.3 | 29.5 ± 17.3 | 26.8 ± 8.4 | 18.8 ± 8.1* | 13.7 ± 8.7* | 34.2 ± 15.7 |
* p < 0.01 when compared to controls
No difference in mean segmental longitudinal εps between CSS and WG were found for longitudinal (p = 0.91), circumferential (p = 0.57) and radial (p = 0.65) measurements
