Introduction: The aim of this study was to investigate an easily available infl ammatory marker and monocyteto-high-density lipoprotein cholesterol ratio (MHR) in patients with cardiac syndrome X (CSX).
Patients and Methods:The study population included 100 patients of which 50 had CSX (CSX group) and 50 had normal coronary angiograms (control group).
Results:Total white blood cell (WBC) count, monocyte count, neutrophil count, NLR, high-sensitivity C-reactive protein (hs-CRP), C-reactive protein (CRP) and MHR were higher in the CSX group (p< 0.05), whereas high-density lipoprotein cholesterol (HDL-C) level was signifi cantly lower in the CSX group as compared with that in the control group (p< 0.05). In the correlation analysis, MHR revealed a signifi cantly positive correlation with hs-CRP (r= 0.375, p< 0.001) and CRP (r= 0.403, p< 0.001). In the multivariate logistic regression analysis, MHR was independently associated with the presence of CSX (odds ratio: 1.250, 95% confi dence interval [CI]: 1.240-1.461, p< 0.001). Using a cut-off level of 90.6, pre-procedural MHR predicted the presence of slow coronary fl ow (SCF) with a sensitivity of 78% and specifi city of 70%.
Conclusion:In conclusion, our fi ndings revealed that higher MHR levels were signifi cantly and independently associated with the presence of CSX.
