Assessment Of Left Ventricular Systolic Function By Speckle Tracking Echocardiography In Young Hypertensive Patients

Abstract

Background: Tissue Speckle Tracking examines speckle aberrations in an echo picture to determine myocardial contractility and relaxation. Reflections, refraction, and dispersion of echo beams generate speckles. Aim of the study: The purpose of this research was to use speckled tracking echocardiography to identify subclinical left ventricular failure in young hypertension individuals who had normal systolic function by 2D echocardiography. Patients and Methods: The research included 30 hypertensive patients with preserved ejection fraction referred to cardiology department at AL azhar University hospital for echocardiography assessment and 20 controls. All patients were assessed clinically followed by M-Mode and 2D echocardiography assessment, pulsed wave Doppler mitral inflow as well as offline speckle tracking echocardiography.Result: Demographic data, anthropometric measurements, blood pressure measurements, conventional tissue Doppler, and strain echocardiography were compared between the two groups. Body mass index, systolic and diastolic blood pressure, left ventricular end diastolyic dimension, interventricular septal diameter, posterior wall diameter, relative wall thickness, left ventricular mass index, end diastolic volume, E/, left atrial diameter, aortic diameter, left atrial volume index, normal systolic velocity of tissue doppler mitral inflow, and GLS. The control group had a considerably greater systolic velocity (p=0.013). In comparison to the hypertension group, GLS was considerably greater in the control group (-21.25± 1.18 vs -19.18±1.66, p=0.001). Conclusion:The final result of the research recommends comprehensive longitudinal stress assessment and tissue Doppler imaging for all newly discovered arterial hypertension patients or patients with arterial hypertension who have normal ejection fraction and suffer from shortness of breath.

Global Left Ventricular Function Index as a Predictor of Subclinical Contractile Dysfunction in Patients with Concentric Left Ventricular Hypertrophy

“…Desai et al [7] conducted a study in adult hypertrophic cardiomyopathy (HCM) with normal LVEF (55%) and found that with patients with LVGFI less than 37% had a primary event versus those with LVGFI more than 37% [8%]. Sa velocity either septal, lateral, and average had the lowest mean value in G3 in agreement with our study Gab Allah et al [17] found that Sa velocity decreased in hypertensive cases than the control. In disagreement with our study, Ayoub et al [16] found no difference between his group studies as regard Sa wave; this discrepancy with our study may be due to different group design according to global longitudinal strain (GLS) and his study included hypertensive patients only.…”
