OBJECTIVE: Cardiac syndrome X (CSX) is typically identified with ischaemia in treadmill exercise test or stress myocardial perfusion scintigraphy as well as angina-like chest pain without stenosis in coronary angiography. The purpose of the present study is to investigate the association between cardiac syndrome X and monocyte-to-HDL cholesterol ratio (MHR) which is a new marker associated with inflammation.
PATIENTS AND METHODS: A total of 230 patients (105 patients with cardiac syndrome X and 125 normal controls) were included in the study. Peripheral venous blood samples were drawn from all study population before coronary angiography for measuring MHR and other haematological parameters.
RESULTS: The patients with cardiac syndrome X were more likely to have higher platelet counts, plateletcrit (PCT), monocyte count and MHR values. Monocyte count and MHR of the CSX group were significantly higher than the control group [0.53 (0.35-1) vs. 0.49 (0.23-0.96); p = .002, .011 (0.006-0.038) vs. 0.010 (0.004-0.034); p < .001, respectively]. HDL-cholesterol levels of the CSX group were significantly lower than the control groups (46.3 ± 10.1 vs. 49.6 ± 11.6; p = .021). Higher MHR and PCT values were found to be associated with the presence of CSX by multivariate logistic regression analysis.
CONCLUSIONS: Elevated MHR level independently was found in association with the presence of CSX. The value of MHR appears additive to conventional expensive methods commonly used in CSX prediction.
