Right ventricular wall thickness and function in hypertensive patients with and without left ventricular hypertrophy: echo-Doppler study.
The structure and function of the right ventricle in arterial hypertension have been the subject of only a few reports. The present study evaluated the functional and structural changes in both left and right ventricles. Doppler and standard echocardiography were performed in 58 hypertensive patients (33 without and 25 with left ventricular hypertrophy). We concluded that right ventricular wall thickness is significantly increased in hypertensive patients compared with normotensive subjects, and that there is a significant, direct correlation between right and left ventricular thickness. Abnormalities in right and left ventricular filling, characterized by a reduction in early and an increase in late diastolic flow velocity, occur in hypertensive patients, and there is a direct correlation between late mitral and tricuspidal flow velocities and left and right ventricular thickness.
