Healthy female volunteers demonstrated higher magnitudes of global longitudinal strain compared to male counterparts (-21.91% vs -18.48%, p<0.001) using feature-tracking CMR at 3.0 T.
Cross-Sectional (n=88)
Single-blind
No
Feature-tracking CMR at 3.0 T is feasible and demonstrates that healthy females have higher global longitudinal strain than males, with global strain measurements showing better reproducibility than segmental strain.

We analyzed feature-tracking derived circumferential and longitudinal strain in healthy volunteers who underwent cardiac magnetic resonance imaging (CMR) at 3.0 T. 88 healthy adults (44.6 ± 18.0 years old, 49% male), without prior cardiovascular disease, underwent CMR at 3.0 T including cine, and late gadolinium enhancement in subjects >45 years. LV functional analysis and feature-tracking strain analyses were carried out. Global strain had better reproducibility than segmental strain. There was a sex specific difference global longitudinal strain (mean ± SD, -18.48 ± 3.65% (male), -21.91 ± 3.01% (female), p < 0.001), but not global circumferential strain (mean ± SD, -25.41 ± 4.50% (male), -27.94 ± 3.48% (female), p = 0.643). There was no association of strain with ageing after accounting for sex for both global longitudinal and circumferential strain. Feature-tracking strain analysis is feasible at 3.0 T. Healthy female volunteers demonstrated higher magnitudes of global longitudinal strain when compared to male counterparts. Whilst global cine-strain has good reproducibility, segmental strain does not.
Mangion et al. (Fri,) conducted a cross-sectional in Healthy volunteers (n=88). Feature-tracking cardiac magnetic resonance imaging at 3.0 T vs. Male vs Female was evaluated on Global longitudinal strain (p=<0.001). Healthy female volunteers demonstrated higher magnitudes of global longitudinal strain compared to male counterparts (-21.91% vs -18.48%, p<0.001) using feature-tracking CMR at 3.0 T.
