Available Datasets: Duke Cardiac Catheterization Datasets

The Duke Databank for Cardiovascular Disease (DDCD) is a clinical care database, established in the 1960s by a research team within the Duke Division of Cardiology. As a component of the DDCD, data were collected on patients undergoing cardiac catheterization for suspected coronary artery or valvular heart disease, and on patients undergoing cardiac surgery. These data were used to generate reports for the patients’ medical records, but were also made available for clinical research, for example, research studies to improve the medical care of patients with coronary artery disease. The Duke-owned DDCD is one of the largest and oldest cardiovascular databanks in the world. Duke researchers have conducted several cardiology outcome studies using this source data.

Duke Cardiac Catheterization Research Dataset (DukeCath)

The DukeCath analysis dataset, extracted from the DDCD, includes records and variables for adult patients undergoing cardiac catheterization procedures at Duke between 1985 and 2013. This dataset has been de-identified in order to remove individually identifiable protected health information. The DukeCath dataset is suitable for clinical and/or methodological research and publications purposes. It contains one record per catheterization procedure and includes patient characteristics, catheterization results, interventional treatments, and long-term outcomes data that allow for assessments of relationships of variables with outcomes, as well as examination of time trends. The dataset includes more than 150,000 catheterization procedures in more than 80,000 unique patients.

Users whose proposals are successfully approved by a review committee will use this data within a secured platform, equipped with statistical and visual analytics tools. Thus far, we share this dataset through SAS and AHA platforms. This dataset has been approved for sharing by Duke University Health System and the Institutional Review Board.


Duke Cardiac Catheterization Educational Dataset (DukeCathR)

The DukeCath educational dataset, a de-identified and anonymized dataset extracted from the DDCD, has been intentionally modified such that any meaningful or publishable clinical interpretations are impossible. DukeCathR provides instructors and students exposure to the "real world" data for instructional analyses. The goal is to provide instructors with a resource to help teach students how to approach statistical analyses using real patient data. Any teacher, instructor, or student can request this dataset for educational purposes.

This dataset has been approved for sharing by Duke University Health System and the Institutional Review Board.
