Hemodynamic Variables Associated with Increased Mortality Risk in Pulmonary Hypertension of Sickle Cell Disease^a

Variable	Adjusted HR	95% CI	P Value
mPAP	1.61/10 mm Hg	1.05-2.45	.027
dPAP	1.83/10 mm Hg	1.09-3.08	.022
TPG	1.78/10 mm Hg	1.14-2.79	.011
PVR	1.44/Wood Unit	1.09-1.89	.009
dPAP – PAWP	2.19/10 mm Hg	1.23-3.89	.008

dPAP = diastolic pulmonary arterial pressure; HR = hazard ratio; TPG = transpulmonary pressure gradient. See Table 1 for expansion of other abbreviations.
