Cardiopulmonary Stress Testing (CPET) AlloSure Study

Sponsor: Baylor Research Institute

View on ClinicalTrials.gov

Summary

1. Cell-free DNA does not vary significantly as a function of the activity of immunologically quiescent cardiac transplant recipients, despite the metabolic demands of the transplanted organ. (The implication of the null result would be that no restrictions to patient activity, nor modification of cardiac rehabilitation prescription, would be necessary to maintain proper test characteristics of AlloSure testing). 2. In immunologically active cardiac transplant allografts, exercise prior to assay of donor-derived cell-free DNA can be used to increase the sensitivity of the AlloSure test. (The implication of this would be that the optimal time-frame for drawing an Allosure may actually be post-exercise, and that window will be characterized).

Interventions

BEHAVIORAL

CPET exercise testing

* The cardiopulmonary exercise testing (CPET) is done. * EKG testing will be done as part of the CPET test. Allosure testing will be done at baseline and then at 1 hr, 4 hrs, 1 day, 7 days after CPET.
