Aerosolized iloprost therapy for pulmonary hypertensive crisis in 4 patients with idiopathic pulmonary arterial hypertension / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To summary the efficacy and safety of aerosolized iloprost in patients with pulmonary hypertensive crisis.</p><p><b>METHODS</b>On the basis of conventional therapy, aerosolized iloprost (10 µg per time for 10 - 15 min in 2 hours interval, 8 times per day) was administered to four patients with idiopathic pulmonary arterial hypertension and pulmonary hypertensive crisis. Blood pressure, heart rate, systemic artery oxygen saturation, systolic pulmonary arterial pressure (sPAP) measured by echocardiography and the adverse events were analyzed.</p><p><b>RESULTS</b>After aerosolized iloprost therapy, sPAP was significantly decreased and systemic artery oxygen saturation was improved. Adverse events (nausea, vomiting, diarrhea, dry cough) were observed in two patients, and the iloprost use was stopped in one patient due to severe vomiting and diarrhea.</p><p><b>CONCLUSION</b>Aerosolized iloprost could significantly reduce the sPAP and improve the systemic artery oxygen saturation in patients with pulmonary hypertension crisis.</p>
