Fig. 1From: Investigation on left ventricular multi-directional deformation in patients of hypertension with different LVEFComparison of multi-directional strains (papillary level) among NC and three subgroups divided according to LVEF. Note that all the strain measurements showed a downward trend from group A to B to C, where SL was impaired in group A and was further impaired in group B and C. SC and SR were impaired in group B and C (all p < 0.05).△ p < 0.05 vs NC group; ▲ p < 0.05 vs group A; ☆ p < 0.05 vs group BBack to article page
