Abstract :

 

Aim:

Assessment of Left ventricular (LV) function in hypertensive patients with left ventricular hypertrophy (LVH) and in those without LVH using two dimensional speckle tracking echocardiography (2D–STE).

 Materials and Methods:

Hundred hypertensive patients were included in the study. Of these 50 patients with LVH and 50 patients with non LVH and all had normal left ventricular ejection fraction (LVEF).  Two–dimensional conventional and speckle tracking echocardiography was done to all patients to assess left ventricle systolic function and global longitudinal strain.

Results:

There was no significant difference between hypertensive patients with LVH and without LVH regarding age and sex distribution. There was significantly higher septal wall thickness (1.2±0.3cm p= <0.001), Posterior wall thickness (1.3±0.4cm p=<0.001), and left atrium size (3.9±0.5) in hypertensive patients with LVH (P < 0.001) compared to non LVH patients. GLS (Global Longitudinal Strain) was significantly decreased in patients with systemic hypertension with LVH (−17.4 ± 3.03) compared to no LVH (–19.6±4.6) patients (P value =0.005).

Conclusion:

This study concluded that there is impairment of left ventricular (LV) systolic function detected by two–dimensional speckle tracking echocardiography in hypertensive patients, especially if associated with LVH with apparently preserved LV systolic function.
