Segmental and global myocardial work in hypertensive patients with different left ventricular geometry

Fig. 1. Segmental longitudinal strain and myocardial work parameters in HT and control subjects. Graph showed mean and error bars across all groups. a MWI, myocardial work index; b MCW, myocardial constructive work; c MWE, myocardial work efficiency; d LS, longitudinal strain (absolute value); e MWW, myocardial wasted work. a P < 0.05 vs control group, b P < 0.05 vs NG group, c P < 0.05 vs CR group; HT, hypertension; NC, normal control; NG, normal geometry; CR, concentric remodeling; CH, concentric hypertrophy; EH, eccentric hypertrophy; Bas-,basal segments; Mid-, middle segments; Api-, apical segments

Fig. 2. Left ventricular longitudinal strain and myocardial work. Examples of patients from: a Control group, b NG, normal geometry group, c CR, concentric remodeling group, d CH, concentric hypertrophy group, e EH, eccentric hypertrophy group. Each graph shows the bull's eye map of segmental longitudinal strain with low-moderate-high myocardial work coded in blue-pink-red, respectively (left); the bull's eye map of segmental myocardial work index with low-moderate-high myocardial work coded in blue-green–red, respectively (right); the parameters of global myocardial strain and myocardial work
