Abstract
OBJECTIVES: The present study was designed to investigate the association of four inflammatory markers and five periodontal indexes with the risk of coronary heart disease (CHD) in 131 patients with type 2 diabetes mellitus (T2DM). METHODS: All subjects were inpatients, including 63 T2DM patients with comorbid CHD ("cases") and 68 T2DM patients without CHD ("controls"). The diagnosis of CHD is based on coronary angiography. RESULTS: Peripheral blood concentrations of high sensitivity C-reactive protein (hs-CRP) (11.51 vs. 10.39 mg/L), leptin (24.60 vs. 21.22 ng/L) and visfatin (65.92 vs. 57.62 ng/L) were significantly higher in cases than in controls (P = .033, 0.041 and 0.041, respectively). The levels of three periodontal indexes - probing pocket depth, attachment loss (AL) and sulcus bleeding index, were significantly higher in cases than in controls, especially for periodontal AL (3.60 mm vs. 3.29 mm, P = .002). A Forward logistic regression was performed for selection, and specifically hs-CRP, leptin, visfatin and periodontal AL were found to be associated with the significant risk of CHD (odds ratio: 1.16, 1.07, 1.03 and 2.04; P = .025, .022, .022 and .010, respectively). Importantly, the benefits of inflammatory markers and periodontal indexes over basic risk factors were significant (likelihood ratio test) and obvious (decision curve analysis). A nomogram was delineated based on significant variables, and it had good accuracy (C-index: 0.801, P < .001). CONCLUSIONS: Our findings support the significant contribution of inflammatory markers and periodontal indexes to the pathogenesis of CHD in T2DM. Specifically, hs-CRP, leptin, visfatin and periodontal AL were identified as significant contributors.
