We Perform Vasoreactivity Test in Pulmonary Hypertension, but Reproducibility?

Sarcoidosis is a chronic, granulomatous disease that it can affect all organs. Pulmonary hypertension (PH) is one of the most important complications of sarcoidosis and indicates poor prognosis. PH is determined by right cardiac catheterization and mean pulmonary artery pressure is ≥25 mmHg at rest. Vasoreactivity test is recommended to this patients, to determine vasodilator drugs to response of pulmonary vascular bed. Calcium channel blockers are used in patients with a positive test vasoreactivity. We presented a case in this article whose vasoreactivity test was positive initially, but negative in follow-up.
