However, currently CMR has no means to directly measure right heart pressures analogous to the invasive RHC... The data collected as follows: right and left ventricular RV/LV EDVI and ESVI; RVEF and LVEF; RV anterior and inferior hinge point angle measurements (systole and diastole); LV diameters to determine eccentricity index in diastole and systole; RV hinge point LGE and right heart catheterization: RV and pulmonary arterial (PA) pressures... A group of 13 non-PAH subjects who underwent routine CMR served as the control group (5 females, 43 ± 3 yrs.; 8 males, 35 ± 13 yrs.)... Regarding the 37 PAH patients, 6 did not have a RHC within the pre-specified time (2 months)... However, for RV pressure multivariate analysis showed that combining Right Ventricular Anterior Angle in systole RVAAs) (r = 0.404), Left Ventricular Eccentricity in systole (LVECCs) (r = 0.43) in a linear regression model, better predicts RV pressure than the variables used separately: RV pressure index = [12.34+0.509*RVAAs+9.031*LVECCs] (r = 0.52, p < 0.01)... For the controls the RV pressure index was lower than in patients (49 ± 6 vs. 71 ± 15, p < 0.001)... Further, LGE grading correlated with the RV pressure, but to a lesser degree (r = 0.49)... Non-invasive testing has been shown to determine the patient's prognostic future... Herein we show RV angles and systolic eccentricity, when combined in a linear regression model better predicts RV pressure than does LGE extent in the RV hinge point region... This model may provide earlier indicator of risk.
