Patients were divided into three groups as early death, no SVG disease (SVGD), and SVGD group. MPV, PDW, and platelet count were evaluated at different times.Results: MPV was significantly higher in the stenotic group than in the nonstenotic group (9.7±1.8 fl and 8.2±0.9 fl, P<0.05). The postoperative MPV ratio was found to be higher in the stenotic group when compared to the preoperative period (9.6±1.8 fl and 7.8±0.9 fl, P<0.05). MPV values were also found to be higher in patients who died during the early stage than in surviving patients (9.4±1.9 fl and 8.0±1.0 fl, P<0.05). There was no statistically significant difference regarding platelet count and PDW ratios between the early deaths group and surviving patients. An MPV value higher than 10.6 predicted SVGD with 85% sensitivity and 45% specificity; and an MPV higher than 7.9 predicted early death with 80% sensitivity and 68% specificity were observed.Conclusion: MPV may be a useful indicator for the prediction of SVGD and mortality following CABG surgery. 2018 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398956442003 https://www.redalyc.org/journal/3989/398956442003/ https://www.redalyc.org/journal/3989/398956442003/html/ https://www.redalyc.org/journal/3989/398956442003/398956442003.epub https://www.redalyc.org/journal/3989/398956442003/movil 10.21470/1678-9741-2017-0247 en http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.4 Vol.33 |
