A recent paper in Transplantation provides recommendations on evaluation and management of pulmonary hypertension (PH) in those being worked up for or have received kidney transplantation. About 20-40%, or even more, of all patients may have pulmonary hypertension due to different reasons.
Given below are the important concepts that help in understanding the pathogenesis of this condition, some controversies and concept, and suggested guidelines for evaluation and management.
- Current classification of PH is based on cardiopulmonary and hemodynamic abnormalities that are common among kidney transplant candidates
- Classifying PH in patients with kidney failure is challenging but must be pursued for optimal management
- PH is common and clinically significant among kidney transplant candidates
- Estimates of PH among kidney transplant candidates have been based on imprecise diagnostic methods
- PH has been associated with adverse outcomes after kidney transplantation
- PH is not always associated with adverse outcomes and transplantation may resolve elevated pulmonary pressures
- Recent advances in the treatment of PH in the general population focus on group 1 disease
- The efficacy of treatments for PH in patients with ESRD before and after transplantation are unproven
