Figure 2.

Association of right ventricular PV loop shape with right heart catheter measurements, augmentation index, and BNP levels. Right heart catheter measurements (PAH, n = 77; non-PH, n = 15) (A–C), augmentation index (PAH, n = 77; non-PH, n = 15) (D), and BNP levels (PAH, n = 45; non-PH, n = 3) (E) were stratified by PV loop shape. Means and standard deviations are shown for mPAP (A) and augmentation index (D). Medians and interquartile ranges are shown for PVR (B), PAC (C), and BNP (E). BNP, B-type natriuretic peptide; mPAP, mean pulmonary arterial pressure; PAC, pulmonary arterial capacitance; PAH, pulmonary arterial hypertension; PH, pulmonary hypertension; PV, pressure-volume; PVR, pulmonary vascular resistance.
