Also, there was no significant difference in the mean HDL as a risk-reducing factor. In deceased patients, the mean hsCRP was 8.89 and higher than the mean hsCRP in the non-deceased group was 6.39. (p=0.146) Also, the mean CPKMB as a known cardiac marker in deceased patients increased slightly (p=0.851).</span></span></span></span></span></span><br> <span style="font-size:10pt"><span style="unicode-bidi:embed"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="background:white"><span cambria="" style="font-family:">Conclusion:</span></span></span></b><span style="font-size:9.0pt"><span style="background:white"><span cambria="" style="font-family:"> The use of hsCRP should be combined with patient age, history of hypertension, history of smoking and history of diabetes mellitus.</span></span></span></span></span></span> CRP, Coronary Artery Bypass Graft Surgery, Mortality 35 38 http://gmedicine.de/browse.php?a_code=A-10-1-17&slc_lang=en&sid=2 H.
