The ISCHEMIA biorepository is a collection of genetic and biomarker samples from randomized participants in the ISCHEMIA and ISCHEMIA-CKD trials. The biorepository will prove an invaluable resource to advance understanding of diagnosis, pathogenesis and outcomes of patients with stable ischemic heart disease. We anticipate this repository will provide a wealth of opportunities for future investigations.

Currently, there are samples from approximately 700-1,000 participants in the biorepository across 6 different sample types.

  • DNA (whole blood and/or saliva)
  • Whole blood RNA
  • Buffy coat
  • Red blood cells
  • Plasma
  • Serum
