Evaluation Of Left Ventricular Long-axis Function In Patients With Essential Hypertension Left Ventricular Hypertrophy Using Real-time Triplane Strain Rate Imaging

Object To evaluate left ventricular (LV) long-axis systolic and diastolic function in essential hypertension (EH) patients with hypertrophy using real-time trip lane strain rate imaging. Methods62EH patients and35age-matched healthy subjects as control group were included.The patients with hypertension were divided into2groups:32patients without LV hypertrophy (NLVH) and30patients with LV hypertroply(LVH). using real-time triplane stain rate imaging measured systolic peak strain rate,early diastolic peak strain and late diastolic peak strain rate (SRs、SRe and SRa) at basal and middle segments in different LV walls. Results:SRs、SRe of all wall in LVH and NLVH group were significant lower than in control group(P<0.05or0.01), significant difference was found between LVH and NLVH group,SRa of lateral wall(LW) and posterior wall (PW) was lower in LVH than the control group (P<0.05).conclusions:Real-time triplance strain rate imaging can quantitative analysis LV long-axis systolic and diastolic function accurately and objectively in patients with EH patients with LVH.
