Abstract P375: Secular Trends in Validity of Troponin I Assays for Myocardial Infarction Classification Among Four US Communities: Findings From the ARIC Study
Abstract:Introduction:
The Atherosclerosis Risk In Communities (ARIC) study conducted community surveillance of hospitalized myocardial infarction (MI) from 1987 to 2014 among four US communities (Jackson MS, Forsyth County NC, Washington County MD, and Minneapolis MN). Surveillance of MI during the troponin era (1996 - ) has been complicated by increasing sensitivity of troponin I assays. It is unclear to what extent increased assay sensitivity has affected the validity of event classification. We hypothes… Show more
