Correlation between arterial stiffness and left ventricular function in patients with primary hypertension

Objective To discuss the correlation between arterial stiffness and left ventricular function in patients with primary hypertension. Methods The patients (n=79) were divided, according to carotid-radial pulse wave velocity (PWV) , into control group (PWV0.9 m/s, n=42) and observation group (PWV≥0.9 m/s, n=37) . All patients were given the examination of color Doppler echocardiography, and the difference in cardiac function parameters were compared between two groups. Results The difference in cardiac function parameters, including left ventricular end-diastolic inner diameter (LVEDd) , left ventricular ejection fraction (LVEF) , left ventricular mass index (LVMI) , mitral early diastole inflow velocity (E) , late diastole inflow velocity (A) and ratio of E to A (E/A) , had statistical significance between two groups (P0.05) . Pearson correlation analysis showed that there was a significant correlation between PWV and LVMI (r=0.347, P0.05) . Conclusion The arterial stiffness is significantly correlated to left ventricular function, and examination of arterial elasticity is significant for reviewing ventricular remodeling in in patients with primary hypertension in clinic.
