ABSTRACT
Objective To adopt the three-dimensional speckle tracking technology to analyze the left ventricular three-dimensional strain in patients with hypertension of normal geometric patterns to provide a basis for early finding the hypertensive cardiac function change.Methods Fifty patients with hypertension of normal geometric patterns and age-matched individuals undergoing physical examination were selected.The routine cardiac parameters were measured with cardiac echocardiography,furthermore the three-dimensional speckle tracking technology was adopted to detect the global longitudinal strain(GLS),global circumferential strain(GCS),global area strain(GAS),global peak radial strain(GRS) and spherical index(SPI).All parameters were compared between the two groups.Results The left ventricular internal diameter,posterior wall of left ventricle,interventricular septum,relative wall thickness(RWT),left ventricular mass index(LVMI),left ventrieular ejection fraetion(EF),SPI and GCS had no statistical differences between the two groups(P>0.05);GLS,GAS and GRS in the hypertension with normal geometric patterns group were significantly lower than those in the control group(P<0.05).Conclusion Three-dimensional speckle tracking technology displays the decrease of left ventricular systolic function in the patients with hypertension of normal geometric patterns,its sensitivity is superior to EF,which is a good method to detect early changes of left ventricular systolic function in hypertension.
