Raised troponin levels are associated with increased risks of death and recurrent myocardial infarction. Greater treatment benefit with low molecular weight heparin, IIb\/IIIa antagonists and revascularisation is seen when troponin levels are raised. There are many implications for patients and society of the new definition including changes in insurability and ability to continue certain occupations. Many more patients, who would previously been diagnosed as having unstable angina, will now be diagnosed as having had an acute myocardial infarction. In addition case fatality rates will fall and comparison with previous epidemiological studies using the old definition will be problematic. However, the new definition may result in greater use of evidence based therapies with improved patient outcomes and decreased community death rates.<\/jats:p>","DOI":"10.1136\/pgmj.2005.035071","type":"journal-article","created":{"date-parts":[[2005,9,2]],"date-time":"2005-09-02T17:13:19Z","timestamp":1125681199000},"page":"552-555","source":"Crossref","is-referenced-by-count":12,"title":["Implications of the new definition of myocardial infarction"],"prefix":"10.1093","volume":"81","author":[{"given":"C-K","family":"Wong","sequence":"first","affiliation":[{"name":"Dunedin School of Medicine , Dunedin , New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H D","family":"White","sequence":"additional","affiliation":[{"name":"Green Lane Cardiovascular Service, Auckland City Hospital , Auckland , New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2005,9,2]]},"reference":[{"key":"2023042408412031300_R1","doi-asserted-by":"crossref","first-page":"959","DOI":"10.1016\/S0735-1097(00)00804-4","article-title":"Myocardial infarction redefined\u2014a consensus document of the Joint European Society of Cardiology\/American College of Cardiology Committee for the Redefinition of Myocardial Infarction","volume":"36","author":"The Joint European Society of Cardiology\/American College of Cardiology Committee","year":"2000","journal-title":"J Am Coll Cardiol"},{"key":"2023042408412031300_R2","volume-title":"Hypertension and coronary heart disease: classification and criteria for epidemiological studies","author":"World Health Organisation Expert Committee","year":"1959"},{"key":"2023042408412031300_R3","doi-asserted-by":"crossref","first-page":"446","DOI":"10.1016\/S0002-8703(03)00245-X","article-title":"Impact of the troponin standard on the prevalence of acute myocardial infarction.","volume":"146","author":"Kontos","year":"2003","journal-title":"Am Heart J"},{"key":"2023042408412031300_R4","doi-asserted-by":"crossref","first-page":"917","DOI":"10.1067\/mhj.2000.111107","article-title":"Elevated cardiac troponin levels predict the risk of adverse outcome in patients with acute coronary syndromes.","volume":"140","author":"Ottani","year":"2000","journal-title":"Am Heart J"},{"key":"2023042408412031300_R5","doi-asserted-by":"crossref","first-page":"1342","DOI":"10.1056\/NEJM199610313351802","article-title":"Cardiac-specific troponin I levels to predict the risk of mortality in patients with acute coronary syndromes.","volume":"335","author":"Antman","year":"1996","journal-title":"N Engl J Med"},{"key":"2023042408412031300_R6","doi-asserted-by":"crossref","first-page":"979","DOI":"10.1016\/S0735-1097(01)01501-7","article-title":"Mechanisms behind the prognostic value of troponin T in unstable coronary artery disease: a FRISC II substudy.","volume":"38","author":"Lindahl","year":"2001","journal-title":"J Am Coll Cardiol"},{"key":"2023042408412031300_R7","first-page":"351","article-title":"Non-ST-elevation acute coronary syndromes: unstable angina and non-ST-elevation myocardial infarction.
