Elected 2015

Dr. de Lemos is Chief of Cardiology at UT Southwestern Medical Center and holds the Sweetheart Ball-Kern Wildenthal, MD, PhD Distinguished Chair in Cardiology. His primary research interests are in early detection, risk assessment and management of cardiovascular disease, with a particular focus on the role of cardiovascular biomarkers. This research is performed within the Dallas Heart Study, a multi-ethnic population-based study, as well as within clinical trials and national registries. His team has evaluated existing biomarkers such as B-type natriuretic peptide, C-reactive protein and cardiac troponins as well as novel biomarkers reflecting biological pathways of disease. His work has contributed to greater understanding of chronic myocardial injury, detected via high sensitivity troponin assays, and the role of small troponin elevations as biomarkers of unrecognized structural heart disease and a powerful predictor of heart failure risk in the population. He also led the development of the American Heart Association's COVID-19 Cardiovascular Registry.
