Objective: We sought to investigate left ventricular mechanics in hypertensive patients with different geometric patterns by using two-dimensional (2DE) and three-dimensional (3DE) strain analysis. Methods: This cross-sectional study included 197 hypertensive individuals who underwent a complete 2DE and 3DE examination. We applied the new updated criteria of left ventricular geometry that considered left ventricular mass index, left ventricular end-diastolic diameter and relative wall thickness. According to this classification the individuals were divided into six groups: normal geometry, concentric remodelling, eccentric nondilated left ventricular hypertrophy (LVH), concentric LVH, dilated LVH and concentric-dilated LVH. Results: Multidirectional 2DE and 3DE left ventricular strain decreased from the hypertensive patients with normal geometry, across the individuals with left ventricular concentric remodelling, eccentric nondilated LVH, to the patients with concentric LVH and dilated LVH patterns. The reduction of left ventricular systolic and early diastolic strain rates was noticed to be heading in the same direction, as well as the elevation of late diastolic strain rates. Left ventricular twist and torsion were increased in the participants with concentric and dilated LVH patterns. Reduced 2DE and 3DE strains were associated with concentric and dilated LVH patterns independent of demographic and clinical parameters. Conclusion: Left ventricular deformation in hypertensive patients is significantly impacted by left ventricular geometry. Concentric and dilated LVH patterns have the greatest unfavourable effect on 2DE and 3DE left ventricular mechanics. The updated classification of left ventricular geometry provides valuable and comprehensive information about left ventricular mechanical deformation and function in hypertensive population.
