Our team studies acute cardiac effects of cardiac problems in pregnancy and disease who preferentially impact women. Our biggest study with be a CMR multisite study looking at baseline cardiac remodeling and serum biomarkers from women with peripartum cardiomyopathy already enrolled in the REBIRTH trial. We will also have a local IRB for CMR, genetics, and serum biomarkers here at Magee. PI is also the site investigator for the international SCAD trial and primarily see SCAD patients in our Magee clinic. Once enrolled to the SCAD trials, participants will need baseline and follow-up CRFs filled out.
