Of 2967 patients, 2838 were 18 years and older at enrollment and 1883 had an RHC within 12 months of an ECHO.

Patients with PAH who had an ECHO and RHC within 12 months of each other were included. The authors investigated ECHO and RHC in patients enrolled in the Registry to Evaluate Early and Long-Term PAH Disease Management (REVEAL), a multicenter, observational, US-based study designed to provide current information about patients with PAH. Whether there is a correlation between these measurements is controversial.
