Patients with rheumatoid arthritis-associated pulmonary arterial hypertension (RA-PAH) have comparable survival to those with idiopathic pulmonary arterial hypertension (IPAH), researchers report.
The team screened 1385 patients and identified 18 RA-PAH patients and 155 IPAH patients who met the inclusion criteria of a mean pulmonary arterial pressure (mPAP) of 25 mmHg or above, pulmonary capillary wedge pressure of 15 mmHg or below and pulmonary vascular resistance of more than 3 Wood units by cardiac catheterisation.
