REasons for Geographic and Racial Differences in Stroke (REGARDS)

REGARDS is cohort of >30,000 participants from across the contiguous 48 United States who enrolled in 2003-2007, and have since been following longitudinally. Outcomes of interest include mortality and cardiovascular hospitalizations including those for heart failure. Within this cohort, we have developed and validated an approach to identify a subset of participation who are free of heart failure as baseline—this has allowed us to identify novel factors contributing to incident heart failure. In addition, we have constructed a cohort of participants who have experienced an adjudicated heart failure hospitalization between 2003 and 2017. This cohort includes >3000 unique hospitalizations, and include chart-level data regarding participant characteristics, hospital events, and hospital characteristics.

Prospective Heart Failure with Preserved Ejection Fraction (HFpEF) Registry

Our registry of HFpEF patients consists of both clinical impressions as well as standard clinical surveys to better help characterize patients with multiple chronic medical conditions across multiple domains especially concomitant geriatric conditions like frailty.

National Health and Nutrition Examination Survey (NHANES)

National survey that is designed to assess the health and nutritional status of adults and children in the United States in order to determine the prevalence of major diseases and risk factors for diseases, including heart failure.

Medicare 5% sample and Medicare Part D

Medicare data on the diagnoses, treatments and clinical events for millions of beneficiaries used for research on delivery systems, benefit designs, and treatments for heart failure.

Nationwide Readmissions Database

Nationally representative information on hospital readmissions for all ages is included in this database and can be used to analyze heart failure readmissions.

Weill Cornell COVID-19 Database

Registry of adults with confirmed COVID-19 within the NewYork-Presbyterian/Weill Cornell Medicine-Lower Manhattan Hospital system in New York City who where hospitalized or presented between March 3 and May 15 2020.
