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.
Results: 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.
