Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The goal of this research study is to understand if a blood test in people who have had heart transplants can detect and predict the following: * Blockages in the small blood vessels of the heart. * Whether small blockages can turn into more severe blockages in the future. Participants will undergo blood draws once every 3 months in the first year of the study (4 blood draws total, taking 15 minutes each) and their medical records will be reviewed for 3 years after the date they are enrolled in the study.
