Key result
Arterial hypertension was associated with significantly increased right ventricular wall thickness and abnormalities in right and left ventricular filling compared with normotensive subjects.
Why the study?
Does arterial hypertension affect right ventricular wall thickness and function compared to normotensive subjects?

Does arterial hypertension affect right ventricular wall thickness and function compared to normotensive subjects?
Arterial hypertension is associated with increased right ventricular wall thickness and abnormal diastolic filling, which correlates directly with left ventricular structural changes.
Hypertension may involve right ventricular remodeling; cross-sectional data leaves open causality and should not yet change practice.
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.

Cuspidi et al. (1989) conducted an observational in Arterial hypertension (n=58). Arterial hypertension vs. Normotensive subjects was evaluated on Right ventricular wall thickness and ventricular filling. Arterial hypertension was associated with significantly increased right ventricular wall thickness and abnormalities in right and left ventricular filling compared with normotensive subjects.
