Layer-specific global longitudinal strain (GLS) has been demonstrated to predict outcome in various patient cohorts. However, little is known regarding the prognostic value of layer-specific GLS in the general population and whether different layers entail differential prognostic information. The aim of the present study was to investigate the prognostic value of whole wall (GLSWW), endomyocardial (GLSEndo), and epimyocardial (GLSEpi) GLS in the general population. Method A total of 4,013 citizens were included in the present study. All 4,013 had 2D-speckle tracking echocardiography performed and analyzed. Outcome was a composite endpoint of incident heart failure (HF) and/or cardiovascular death (CVD). Results Mean age was 56 years and 57up time of 3.5 years, 133 participants (3.3 reached the composite outcome. Sex modified the relationship between all GLS parameters and outcome. In sex stratified analysis, no GLS parameter remained significant predictors of outcome in females. In contrast, GLSWW (HR=1.16, 951.02;1.31], per 1 and GLSEpi (HR=1.19, 951.04;1.38], per 1 remained as significant predictors of outcome in males after multivariable adjustment (including demographic, clinical, biochemistry, and echocardiographic parameters). Lastly, only in males did GLS parameters provide incremental prognostic information to general population risk models. Conclusions In the general population, sex modifies the prognostic value of GLS resulting in GLSEpi being the only layer-specific prognosticator in males, while no GLS parameter provides independent prognostic information in females.
