ASSESSMENT OF THE LEFT VENTRICULAR STIFFNESS USING SPECKLE-TRACKING ECHOCARDIOGRAPHY IN PATIENTS WITH PRIMARY HYPERTENSION
Main Article Content
Abstract
Objectives: To investigate left ventricular stiffness (LVS) using speckle-tracking echocardiography (STE) in patients with primary hypertension. Methods: A cross-sectional descriptive, controlled study was conducted on 134 subjects who were divided into 2 groups: The primary hypertension group (consisting of 103 patients) and the control group (comprising 31 healthy individuals of similar age and gender). All study subjects underwent echocardiography to assess diastolic left ventricular wall strain (DWS) and LVS by tissue Doppler ultrasound (TDI) and STE. Results: DWS and E/LASr/EDV in the hypertensive group were higher than those in the control group. E/e’/EDV between the two groups had no difference. LVS with all 3 calculation methods was positively correlated with age and degree of weakness, but no difference was found between the two sexes. There was no difference in DWS and E/e’/EDV between the hypertensive group ≤ 5 years and > 5 years. E/LASr/EDV in the hypertensive group > 5 years was significantly higher than in the hypertensive group ≤ 5 years. Conclusion: The primary hypertension group had higher DWS and LVS measured by STE than the control group. LVS with all 3 calculation methods was positively correlated with age and level of weakness. LVS measured by E/LASr/LVEDV was associated with the duration of hypertension.
