UT Southwestern team wins grand prize in American Heart Association Data Challenge


A team led by University of Texas (UT) Southwestern Medical Center cardiologist Ambarish Pandey, M.D., was awarded the grand prize in the American Heart Association Heart Failure Data Challenge hosted by the American Heart Association and the Association of Black Cardiologists, a media release from the university said. The six-month data challenge asked researchers to test the relationships between heart failure and health disparities, social determinants of health, and structural determinants of health.

Dr. Pandey’s team included UT Southwestern colleagues Shreya Rao, M.D., M.P.H., and Sandeep Das, M.D., M.P.H., M.B.A.; and Matthew W. Segar, M.D., M.S., of the Texas Heart Institute in Houston.

According to the university, their project, ‘Impact of Social and Structural Determinants of Health on Hospital Length of Stay among Heart Failure Patients according to Race’, focused on correlations between hospital length of stay for patients with heart failure and ZIP codes, using data from the American Heart Association to examine Black versus non-Black populations and geographic areas across the country.

“It is well-established that Black individuals have a disproportionately higher burden of heart failure and worse access to care outside of the hospital, and that social determinants of health are important drivers of these disparities,” said Dr. Pandey, a general cardiologist with interest in heart failure research, was quoted by the university as saying.

“In this study, we focused on how neighborhood-level measures of social determinants of health impact length of stay for heart failure hospitalization among patients who self-report as Black and contrasted it with patients of other races.”

The social determinants of health included neighborhood-level measures of income, education, housing stability, social support, access to transportation, rural vs. urban location, and proportion of individuals who were foreign-born with limited English proficiency in the community.

The American Heart Association is a voluntary organization that recognizes social determinants of health, including structural racism, as a major cause of poor health and premature death from heart disease and stroke.

A UT Southwestern report quoted Michelle A. Albert, M.D., M.P.H., president of the American Heart Association and immediate past president of the Association of Black Cardiologists, as saying, “Improving our understanding of how social determinants of health impact certain populations in order to develop consequential targeted solutions requires harmonization of different types of data.”

The team used the American Heart Association’s Precision Medicine Platform to investigate key questions around socioeconomic disparities and heart failure outcomes. The Precision Medicine Platform is an easy-to-use research interface that allows researchers to collaborate from anywhere in the world in a secure, cloud-based environment. With artificial intelligence and deep machine-learning capabilities, the Precision Medicine Platform gives researchers the power and speed to bring their data together collaboratively and accelerate their findings into impactful discoveries for patients faster than ever before.
