Abstract

AIM: Experimental and clinical evidence supports the view that right ventricular hypertrophy (RVH) may parallel left ventricular hypertrophy in systemic hypertension; a comprehensive analysis of this issue, however, is lacking. Thus, we analyzed the literature in order to provide an updated information on the right ventricular structural changes associated to systemic hypertension. DESIGN: A literature search using the key words 'right ventricle' 'right ventricular hypertrophy', 'biventricular hypertrophy' 'right and left ventricular hypertrophy'. 'hypertension', 'echocardiography' was performed in order to identify relevant articles. Full articles published in English language in the last three decades reporting studies in adult hypertensive individuals were considered. RESULTS: A total of 13 studies, including 1290 untreated (45%) and treated hypertensive patients and 259 normotensive controls, were considered. Overall, in hypertensive individuals right ventricular wall was thicker than in normotensive counterparts (standardized difference 1.3 mm, P <0.001). RVH prevalence consistently varied among studies (17.0-80.0%) with an average of 28.6% in the pooled population. This was also the case for LVH prevalence rates (9.0-100%) with an average value of 30.6%. CONCLUSION: Clinical studies consistently indicate that RVH is a common cardiac phenotype in systemic hypertension. As this finding is based on a limited number of cross-sectional studies including small population samples, further investigations are needed to determine the clinical utility and prognostic value of this phenotype in clinical practice.
