Four of these 1027 patients had a positive exercise stress test (0.4% incidence of positive exercise stress testing). Of those, three patients had subsequent non\u2010invasive functional testing that yielded a negative result. One patient declined further investigations. Assuming this was a true positive exercise stress test, the incidence of true positive exercise stress testing would have been 0.097% (95% confidence interval: 0.079\u20130.115%) (one of 1027 patients).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Routine exercise stress testing has limited value in the risk stratification of adults less than 40 years with suspected intermediate risk of acute coronary syndrome.<\/jats:p><\/jats:sec>","DOI":"10.1111\/1742-6723.12222","type":"journal-article","created":{"date-parts":[[2014,4,8]],"date-time":"2014-04-08T01:53:02Z","timestamp":1396921982000},"page":"170-176","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Limited utility of exercise stress testing in the evaluation of suspected acute coronary syndrome in patients aged less than 40 years with intermediate risk features"],"prefix":"10.1111","volume":"26","author":[{"given":"Adam C","family":"Scott","sequence":"first","affiliation":[{"name":"Department of Cardiology Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"},{"name":"School of Public Health Queensland University of Technology  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Bilesky","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arvin","family":"Lamanna","sequence":"additional","affiliation":[{"name":"Department of Cardiology Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"},{"name":"School of Medicine University of Queensland  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louise","family":"Cullen","sequence":"additional","affiliation":[{"name":"School of Public Health Queensland University of Technology  Brisbane Queensland Australia"},{"name":"Department of Emergency Medicine Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"},{"name":"School of Medicine University of Queensland  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"FT Brown","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"},{"name":"School of Medicine University of Queensland  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles","family":"Denaro","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Parsonage","sequence":"additional","affiliation":[{"name":"Department of Cardiology Royal Brisbane and Women's Hospital  Brisbane Queensland Australia"},{"name":"School of Medicine University of Queensland  Brisbane Queensland Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,4,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","unstructured":"AIHW.Cardiovascular disease: Australian facts 2011.
