Patients with a positive cardiac history were more likely to have a LVEF of \u2a7d45 per cent (P &amp;lt; 0\u00b7001). The operative mortality rate was 4 per cent. Each of three patients who died had a LVEF \u2a7d35 per cent and developed cardiac failure which led to renal failure. Five other patients developed cardiac failure manifested by acute pulmonary oedema during the early postoperative period. There was no statistically significant association between a positive cardiac history and the occurrence of postoperative cardiac failure or death. However, patients with a LVEF of \u2a7d45 per cent were more likely to develop postoperative cardiac failure (P = 0\u00b7004) while patients with a LVEF of &amp;gt;35 per cent had a greater chance of dying (P &amp;lt; 0\u00b7001). No patient died with a LVEF &amp;gt; 35 per cent. Preoperative evaluation of LVEF can select patients at high risk of cardiac death from repair of abdominal aortic aneurysm. Such patients could be followed conservatively if they remain asymptomatic and the aneurysm does not enlarge. If operation is considered mandatory, patients with a low LVEF should receive intensive perioperative monitoring with enhancement of ventricular performance.<\/jats:p>","DOI":"10.1002\/bjs.1800760109","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T11:16:51Z","timestamp":1172920611000},"page":"26-28","source":"Crossref","is-referenced-by-count":42,"title":["Risk of aortic aneurysm surgery as assessed by preoperative gated heart pool scan"],"prefix":"10.1093","volume":"76","author":[{"given":"J P","family":"Fletcher","sequence":"first","affiliation":[{"name":"Department of Surgery, Westmead Hospital , Westmead, New South Wales, 2145","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V F","family":"Antico","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Westmead Hospital , Westmead, New South Wales, 2145","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Gruenewald","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Westmead Hospital , Westmead, New South Wales, 2145","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L Z","family":"Kershaw","sequence":"additional","affiliation":[{"name":"Department of Surgery, Westmead Hospital , Westmead, New South Wales, 2145","place":["Australia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[1989,1,1]]},"reference":[{"key":"2024092806222597800_bib1","first-page":"315","article-title":"A modified method for the in-vivo labelling of red blood cells with Tc-99m: concise communication","volume":"23","author":"Callahan","year":"1982","journal-title":"J Nucl Med"},{"key":"2024092806222597800_bib2","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1016\/S0001-2998(84)80022-7","article-title":"Radionuclide-labelled red blood cells: current status and future prospects","volume":"14","author":"Srivastava","year":"1984","journal-title":"Semin Nucl Med"},{"key":"2024092806222597800_bib3","first-page":"128","article-title":"A software package for the analysis of gated cardiac blood pool studies","volume":"5","author":"Hutton","year":"1982","journal-title":"Australas Phys Eng Sci Med"},{"key":"2024092806222597800_bib4","doi-asserted-by":"crossref","first-page":"296","DOI":"10.1016\/S0001-2998(79)80015-X","article-title":"Of linens and laces: the eighth anniversary of the gated blood pool scan","volume":"9","author":"Strauss","year":"1979","journal-title":"Sem Nucl Med"},{"key":"2024092806222597800_bib5","first-page":"622","article-title":"Aneurysm of abdominal aorta.
