The Astronaut Cardiovascular Health and Risk Modification (Astro-CHARM) calculator is a tool that incorporates traditional risk factor information with coronary artery calcium (CAC) score results to provide an individual’s estimated 10-year risk of atherosclerotic disease (ASCVD) events, including fatal or non-fatal heart attack or stroke. It is intended for use in younger individuals (ages 40-65) without a prior history of ASCVD. The Astro-CHARM was developed using data from three large, population-based cohorts (the Multi-Ethnic Study of Atherosclerosis, Dallas Heart Study, and Prospective Army Coronary Calcium Project), and validated in a fourth cohort (the Framingham Heart Study).
Who developed it?
Development of the Astro-CHARM was supported by the National Space Biomedical Research Institute (NSBRI) in collaboration with a research group led by Dr. Amit Khera from UT Southwestern Medical Center.
Astro-CHARM (the “App”) assists patients and healthcare providers in estimating the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) incorporating traditional cardiovascular risk factors and coronary artery calcium score values. The App is intended for informational and educational purposes only and is not a substitute for professional care by a qualified medical professional. The App does not constitute medical advice or services. Using and accessing the App does not create a physician-patient relationship between the App owner and the user. It should not be used by patients without direct consultation and supervision of their healthcare provider. The use of the App is provided on an “as is” basis. The App owner, its affiliates, licensors, and content contributors, to the fullest extent provided by law, are not responsible for ensuring that your implementation of the App or the site content or the results of the App will be clinically sound, error-free, or that defects, if any will be corrected.
