Prognosis of pulmonary arterial hypertension patients with pericardial effusion before and after initiation of parenteral prostacyclin therapy

Abstract Few studies have evaluated the effects of pulmonary arterial hypertension therapies on pericardial effusion. We evaluated hemodynamics, echocardiograms, and outcomes for 119 parenteral prostanoid‐treated patients. We discovered an increased frequency of pericardial effusions posttreatment, and that a moderate‐large pericardial effusion at initiation, but not at 1st follow‐up, was significantly associated with mortality.
