Oregon Sudden Unexpected Death Study (SUDS)

The Oregon Sudden Unexpected Death Study, founded by Sumeet S. Chugh MD in 2002, is conducted by the Arrhythmia Research Laboratory at the Cedars-Sinai Heart Institute, Cedars-Sinai Health System, Los Angeles, working closely with long-term collaborators in the Department of Emergency Medicine, Oregon Health and Science University, Portland, Oregon. The study is based in the Portland, Oregon metropolitan area, in a population of approximately one million residents. Since 2002, this study has collected detailed information on SCA cases, including patient demographics and past medical history, as well as blood samples to investigate genetic and biochemical markers of risk. This study, originally underwritten by the US Centers for Disease Control (CDC), is currently funded by grants from the National Heart, Lung, and Blood Institute (NHLBI) and the American Heart Association.
