Q: Which of the following marker is a good predictor of mortality in patients with severe pulmonary hypertension who undergoes heart-lung transplant?
D) High LDH level
E) baseline PO2 on room air prior to transplant
End stage pulmonary hypertension results in hyperbilirubinemia due to chronic passive hepatic congestion. Persistent hyperbilirubinemia has been found to be a good marker of postoperative mortality in heart-lung transplant recipients due to end stage pulmonary hypertension.
