Valsartan Versus Amlodipine Effect on Left Ventricular Multidirectional Deformation and Adipocytokines Levels in Hypertensive Patients: Speckle Tracking Echocardiography.

INTRODUCTION: Structural and functional properties of the left ventricle (LV) wall have been reported to be altered in hypertension, even at early stages of the disease. Abnormal adipokine levels affect blood pressure regulation. Hypo-adiponectinaemia and hyper-leptinaemia were reported in hypertension.

AIM: To evaluate the effects of valsartan versus amlodipine on LV deformation also, on plasma adiponectin and leptin levels in hypertensive individuals.

METHODS: LV strain was measured by two-dimensional speckle tracking echocardiography, plasma levels of adiponectin and leptin was determined in 30 healthy individuals served as control group and in 200 hypertensive patients before and after treatment for 6 months with either valsartan 160 mg or amlodipine 10 mg.

RESULTS: Compared to control group longitudinal strain was significantly affected in hypertensive patients, adiponectin was significantly lower while TNF-α, hs-CRP and leptin levels were significantly higher in hypertensive group. A significant improvement in LV functions, along with a decrease in leptin and increase in adiponectin levels in valsartan group compared to amlodipine group.

CONCLUSIONS: Our results indicate that valsartan is superior to amlodipine when it comes to affecting the hormonal function of human adipose tissue. Valsartan has a beneficial effect on LV deformation and function presented in GLS.
