Abstract:
Patients with increased pulmonary vascular resistance may experience acute pulmonary hypertension after heart transplantation. Pulmonary vasodilator drugs usually are delivered by the intravenous or the endotracheal route during acute pulmonary hypertensive crisis. Oral pulmonary vasodilators have a potential role in less acutely ill patients with increased pulmonary artery pressure after heart transplantation. We describe the 1st successful post-operative use of oral sildenafil for pulmonary vasodilation in a patient after heart transplantation.

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...
Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
