Theaim of this study was to evaluate the relationship between postoperative troponin T (TnT) elevationwith the associated postoperative mortality, and mean hospital stay.Methods: This was a prospective observational study of consecutive patients who underwentopen aortoiliac surgery during 2006. TnT levels in the first 72 hours after the operation, immediatemortality, postoperative care unit stay, and total postoperative hospital stay were recorded.Statistical analyses were performed with the program SPSS 14.0; the chi-square test (or theFisher’s exact test) was used for qualitative variables and the ManneWhitney test for quantitativevariables.Results: Of the 65 patients included in the study, postoperative TnT was elevated in 14 (21.5%)patients. No significant differences were found in age, sex, hypertension, dyslipidemia, smoking,diabetes mellitus, ischemic heart disease, heart failure, bronchopathy, or renal failure betweengroups. Mortality in patients with elevated TnT levels was significantly higher (42% comparedwith 3.92%; relative risk 10.93 ± 0.76; p ¼ 0.001). Likewise, their mean postoperative intensivecare unit stay was significantly greater (23.21 ± 6.96 days compared to 2.86 ± 1.96; p < 0.001).This finding resulted in a significantly longer postoperative hospital stay (32.57 ± 25.38 dayscompared with 12.47 ± 2.21).Conclusion: TnT level in the immediate postoperative period is a highly relevant indicator ofprognosis in patients undergoing major vascular surgery PB Elsevier SN 0890-5096 YR 2013 FD 2013 LK http://uvadoc.uva.es/handle/10324/3388 UL http://uvadoc.uva.es/handle/10324/3388 LA eng NO Angiology and Vascular Surgery Division, 2010, vol.24. p.747-751 NO Producción Científica DS UVaDOC RD 29-mar-2024
