Objective:To evaluate right ventricular function in primary hypertension patients with left ventricular hypertrophy by 2-dimensional speckle tracking imaging. Methods:Sixty primary hypertension patients were enrolled into this study

and divided into 2groups according to left ventricular mass index（LVMI）:left ventricular hypertrophy（group B

n=30）

without left ventricular hypertrophy（group A

n=30）. Echocardiographic parameters were measured

including ventricular size

left ventricular thickness

left ventricular ejection fraction（LVEF）

tricuspid annular plane systolic excursion（TAPSE）

right ventricular fractional area change（RVFAC）

left ventricular global longitudinal peak systolic strain（LVGLS） and right ventricular each segment longitudinal peak systolic strain.Results:No significance was observed between groups in ventricular diameters

LVEF

TAPSE

RVFAC（P>0.05）. The wall thickness and LVMI of group B were significantly higher than those of group A（P<0.05）. LVGLS and right ventricular each segment longitudinal peak systolic strain of group B were significantly lower than those of group A（P<0.05）. LVGLS with TAPSE

RVFAC

0.317;P<0.05）. LVMI and right ventricular each segment（RVLSbas

IVSLSapi）longitudinal peak systolic strain were negatively correlated（r:-0.318

-0.305

-0.328

-0.340

-0.268;P<0.05）

while there was no correlation between TAPSE and RVFAC. Conclusion:2D-STI can quantitatively evaluate right ventricular function in primary hypertension patients with left ventricular hypertrophy

and is superior to traditional echo parameters. Left ventricular hypertrophy and left ventricular global function damage can indirectly affect right ventricular function.
