Prognostic Value of Echocardiographic Variables Before and After Initiation of Parenteral Prostacyclin Therapy: An Observational Study.
Echocardiographic parameters are used as prognostic markers in patients with pulmonary arterial hypertension (PAH) receiving parenteral (IV or subcutaneous [IV/SC]) prostacyclin therapy. However, data on how posttreatment echocardiographic results associate with outcomes are limited. ⋯ Echocardiographic variables improved following IV/SC therapy, and multiple echocardiographic measures associated significantly with survival, particularly when reassessed after at least 90 days of therapy. RA size in particular may be useful in prognostication in follow-up of patients with PAH on IV/SC therapy.
