Spontaneous Coronary Artery Dissection

Dr. Sharonne Hayes on SCAD Registries Kept by the Mayo Clinic and Collaborations with Other Institutions (Part 2)

May 8, 2023

Interview with Dr. Sharonne Hayes – Part 2

Mayo Clinic SCAD Research Program Team Lead

In Part 1 of our interview with Dr. Hayes, an internationally recognized SCAD expert, our focus
was on Mayo Clinic’s two SCAD related registries – their main registry, which currently has 1500
participants and their SCAD Biobank used for genetic research.

In Part 2, Dr. Hayes shares examples of how Mayo Clinic collaborates and shares their registry
data. This data has been deidentified to protect participants’ privacy. These examples are in
addition to Mayo Clinic’s own SCAD research they do internally.

Question 3: What are some examples of Mayo Clinic Collaborative Efforts with
Other Research Institutions?

An important example includes the 2019 international collaboration (Adlam D, Olson T, et al, below) in which Mayo Clinic’s SCAD Research team were able to provide the vast majority of samples for analysis, as well as additional deep phenotyping information about Mayo participants, as a result of our robust information abstraction (also funded by SRI!):

Most non-Mayo collaborators included:

  • Institute for Health Research (NIHR) Leicester Biomedical Research Centre, Glenfield Hospital, Leicester, United Kingdom
  • University Hospital of Clermont-Ferrand, Auvergne University, Clermont-Ferrand, France
  • Mount Sinai, New York, New York
  • Victor Chang Cardiac Research Institute, Sydney, New South Wales, Australia
  • INSERM, Paris Cardiovascular Research Center, Paris, France
Other ongoing research Collaborations:

We have several other ongoing research collaborations, including another international collaboration where the Mayo Clinic SCAD Biobank participated in a project led by Dr. Nabila Bouatia-Naji from France. It was presented in abstract form at the 2022 American Heart Association’s Annual Sessions in November.
