The relation between blood routine test indicators and advanced saphenous vein graft disease in patients with coronary artery bypass grafting / 天津医药

ABSTRACT

Objective To investigate the correlation between blood routine test indicators and advanced saphenous vein graft disease (SVGD) in patients with coronary artery bypass grafting (CABG). Methods By defining SVGD as an occlusion of 50% or more of the saphenous vein graft (SVG) excluding distal anastomotic occlusion, patients were divided into SVGD group and non-SVGD group, who suffered CABG over 1 year with recurrent angina and underwent coronary angiography (CAG) operation from March 2015 to January 2016 in Tianjin Chest Hospital. Results of blood routine test data were compared between two groups. The multivariable Logistic regression was analyzed for the relationship between blood routine test indicators and advanced SVGD. Results There were 148 patients in the study, 109 patients in SVGD group and 39 patients in non-SVGD group. There were significant differences in level of red blood cell distribution width (RDW0.123 2 ± 0.008 9 vs. 0.120 2 ± 0.005 2, P0.127 5[OR (95%CI)4.905 (1.058-22.747), P=0.042], NLR>3.34[OR(95%CI)4.013(1.466-10.987), P=0.007]were independent risk factors for advanced SVGD, as well as PCT>0.185 [OR(95%CI)2.636(1.098-6.324), P=0.030]might be risk factor for advanced SVGD. Conclusion RDW>0.127 5, NLR>3.34 could indicate advanced SVGD. We need more samples to support that PCT>0.185 is used to be risk indicators for advanced SVGD.
