Right ventricular hemodynamic function (mean pulmonary artery pressure, mean right atrial pressure, and cardiac index) is closely associated with mortality in primary pulmonary hypertension.
Mortality was most closely associated with right ventricular hemodynamic function and can be characterized by means of an equation using three variables: mean pulmonary artery pressure, mean right atrial pressure, and cardiac index. Such an equation, once validated prospectively, could be used as an adjunct in planning treatment strategies and allocating medical resources.
D’Alonzo et al. (Sun,) studied this question.
