Propensity-Matched Study of Cardiac Contractility Modulation Therapy in Heart Failure

Data for both the CCM treatment arm and a propensity-matched control group come from a large, de-identified, aggregated electronic health record (EHR) database containing patient information from multiple U.S. healthcare systems. The database includes demographics, clinical notes, imaging, laboratory results, medications, social determinants of health, and other relevant healthcare information, with up to 8 years of historical clinical data updated regularly.
