NCT ID: NCT03545672
Last Updated: 2024-08-09
Results Overview
All PBC patients are followed up through telephone or by retrieving outpatient medical record systems. Cardiac events include: 1. cardiac death; 2. myocardial infarction; 3. hospitalization for unstable angina.

Participant Flow
This was a prospective, three-center, cardiac imaging observational study. The study was open for recruitment between September 2017 and January 2019. The first participant was enrolled on October 23, 2017 and last participant was enrolled on January 8, 2019
Of 119 enrolled participants. 112 participants were included and randomized to observational study group.
