Of 99 patients with myocardial infarction and appendicitis, 87 underwent appendicectomy; and of 221 with myocardial infarction and hip fracture, 179 were operated on. The patients were studied on an intention to treat basis. The mortality within one month was 9% and 16% respectively. A history of congestive heart failure was the dominating risk factor, while ischaemic heart disease (recent myocardial infarction or angina pectoris) had no independent association with mortality. If the ventricular function is known additional preoperative information about the heart is of negligible value when estimating the mortality of non-cardiac surgery.<\/jats:p>","DOI":"10.1136\/bmj.297.6655.1011","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T15:19:55Z","timestamp":1238685595000},"page":"1011-1013","source":"Crossref","is-referenced-by-count":15,"title":["Cardiac predictors of death after non-cardiac surgery evaluated by intention to treat."],"prefix":"10.1136","volume":"297","author":[{"given":"A.","family":"Dirksen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Kj\u00f8ller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1988,10,22]]},"reference":[{"key":"ref_1","first-page":"1511","article-title":"Evaluation and management of patients with heart disease who undergo non-cardiac surgery","volume-title":"The heart","author":"Logue, R.B.","year":"1986","unstructured":"Logue RB.
