There are limited data reported on the myocardial ECV in an essential hypertension patient population. The purpose of this study was to determine whether extracellular volume fraction (ECV) quantification by cardiac magnetic resonance (CMR) can demonstrate left ventricle (LV) abnormalities in a cohort of consecutive hypertension (HTN) patients, and to investigate the relationship between ECV and global LV function and LV remodelling.


ECV quantification with cardiac MR imaging was prospectively performed in 134 consecutive HTN patients and 97 healthy subjects. The HTN patients were separated into two subgroups according to LGE present or not. Individual and regional ECV were compared to the regions on LGE images using a 17-segment model. Statistical comparisons of LV global functional parameters, and ECV were carried out using the Pearson correlation, Student t test, and multiple regressions.


In HTN group, 70.1 %( 94/134) was LGE negative and 29.9% (40/134) was LGE positive. The average ECV in healthy controls and LGE negative patients were 26.9 ± 2.67 % and 28.5 ± 2.9% (P<0.001), respectively. The differences of ECV reached statistical significance among the regions of LGE area, LGE-Peri area, LGE remote area and the normal area of the control group(all P<0.05) in LGE positive subgroup. Global ECV significantly correlated with LVEF (r=-0.466, P < 0 .001) and LV hypertrophy (r= 0.667, P < 0.001).


ECV imaging by cardiac MR imaging can identify LV abnormalities at an early stage in HTN patients without LGE. These abnormalities may reflect increase in diffuse myocardial fibrosis and are associated with LV remodelling.
