To ascertain the validity, in-patient records containing the ICD-codes 410\u2013411 and 430\u2013438 were validated. First event of acute myocardial infarction and acute stroke suggested in the in-patient register could be confirmed in 96% and 94%, respectively. In-patient diagnoses of suspected acute myocardial infarction or other acute or subacute ischemic heart diseases, transient ischemic attack and unspecified cerebrovascular disease revealed high proportions of what in fact turned out to be definite events (11%, 24% and 53% respectively). It is concluded that disease ascertainment for this cohort study claims validation of register data with hospital records.<\/jats:p>","DOI":"10.1177\/140349489302100102","type":"journal-article","created":{"date-parts":[[2009,2,9]],"date-time":"2009-02-09T12:33:36Z","timestamp":1234182816000},"page":"3-9","source":"Crossref","is-referenced-by-count":120,"title":["Validity of register data on acute myocardial infarction and acute stroke"],"prefix":"10.1177","volume":"21","author":[{"given":"Ulf","family":"Lindblad","sequence":"first","affiliation":[{"name":"Ulf Lindblad, From the Department of Community Health Sciences, University of Lund, Malm\u00f6"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lennart","family":"R\u00e5stam","sequence":"additional","affiliation":[{"name":"Lennart R\u00e5stam, From the Department of Community Health Sciences, University of Lund, Malm\u00f6, Address for offprints: Lennart R\u00e5stam Dept of Community Health Sciences University of Lund S-214 01 Malm\u00f6 Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonas","family":"Ranstam","sequence":"additional","affiliation":[{"name":"Jonas Ranstam, From the Department of Community Health Sciences, University of Lund, Malm\u00f6"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magnus","family":"Peterson","sequence":"additional","affiliation":[{"name":"Magnus Peterson, Department of Medicine, Lidk\u00f6ping Hospital, Lidk\u00f6ping, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1993,3,1]]},"reference":[{"issue":"626","key":"atypb1","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1111\/j.0954-6820.1979.tb00816.x","volume":"205","author":"Berglund, G.","year":"1979","journal-title":"Acta Med Scand"},{"key":"atypb2","first-page":"249","volume":"219","author":"R\u00e5stam L","year":"1986","journal-title":"II.
