Methods: Atrial tissue was obtained from the right appendage during open surgery in 25 patients with RHD. The mRNA of ACE and ERK2 and AT1R was semi-qualified by reverse transcription-ploymerase chain reaction and normalized to the glyceraldehyde 3-phosphate dehydrogenase. Western blotting analysis was employed to examine the expression of ACE and ERK and AT1R. Atrial collagen volume fraction was detected by Masson's stain.
