Steven E. Nissen (born 1948), is a cardiologist, researcher and patient advocate. He is chairman of cardiovascular medicine at the Cleveland Clinic, in Cleveland, Ohio.〔Steven Nissen MD, physician profile (), Cleveland Clinic, retrieved 2/2010〕 Nissen graduated high school from the Webb School of California and pursued his undergraduate degree at the University of Michigan. He then went on to receive his medical degree from the University of Michigan School of Medicine in Ann Arbor. He completed his internal medicine internship and residency at the University of California, Davis in Sacramento, thereafter completed his cardiology fellowship at the University of Kentucky Medical Center in Lexington.〔 Joining Cleveland Clinic in 1992, Nissen served as Vice-Chairman of the Department of Cardiology (1993–2002), Section Head of Clinical Cardiology (1992–2000) and Director of the Coronary Intensive Care Unit (1992–1997). Most recently, he served as Medical Director of the Cleveland Clinic Cardiovascular Coordinating Center (C5), an organization that directs multi-center clinical trials. Nissen still attends in the Cardiac Critical Care Unit periodically throughout the year.〔 ==Imaging technology== Nissen is the primary force behind an imaging technology called intravascular ultrasound (IVUS) which allows researchers to see and measure atherosclerosis, the fatty plaque that attaches to the walls of coronary arteries and cannot be detected on an angiogram. In particular, Nissen developed the methodology for application of IVUS in the assessment of the progression and regression of coronary atherosclerosis. He produced the first images in humans in 1990 and began using IVUS to document the ubiquitous prevalence of coronary artery disease. The technology has been the basis for his research during the last decade and Nissen is currently the principal investigator for several large IVUS atherosclerosis trials. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Steven Nissen」の詳細全文を読む スポンサード リンク
