GLS in relation to left ventricular mass index in controls and patients with aortic stenosis. The range of average peak longitudinal strain in subjects with normal (group 1), mildly increased (group 2) and moderately to severe (group 3) increased LVMi and aortic stenosis, controls and the whole study group (n = 38). Left ventricular mass measurements indexed for body surface area were done with MRI. P = 0,001 for comparison between three groups by full-factorial Anova analysis of variance. #1 P = 0,008 between average peak longitudinal strain in group 1 vs. group 2 and #2 p = 0,004 between the group1 and group 2 by the Bonferroni post hoc test, respectively. *p < 0,001. GLS = global longitudinal strain, LVMi = left ventricular mass index.
