Abstract:
Introduction: Recent evidence suggests that systemic inflammation not only plays an
important role in the pathogenesis of Acute Coronary Syndrome but also correlates with disease
severity. Monocyte-to-high-density lipoprotein cholesterol ratio (MHR), Neutrophil-Lymphocyte
Ratio (NLR), and Monocyte-Lymphocyte Ratio (MLR) are novel systemic inflammation markers
used for predicting the burden of coronary artery disease (CAD) based on SYNTAX Score.
This single-center, cross-sectional, observational study compared the association of these novel
hematological indices with CAD severity using the SYNTAX Score in ACS patients and aimed
to determine the best predictor of the severity of CAD.
Methods: A total of 403 consecutive patients with ACS who underwent coronary angiography
were enrolled. On the basis of the SYNTAX Score, patients were divided into three groups:
Low: <22, Moderate 22 - 32 and High ≥ 32. MHR, MLR, and NLR were calculated and correlated
with SYNTAX Score.
Results: All three indices: MHR (r=0.511; p <0.001), MLR (r=0.373; p <0.001), and NLR
(r=0.292; p =0.001) showed significant correlation with SYNTAX Score. The MHR ROC was
significantly higher than that of MLR (difference between area: 0.158; 95% CI: 0.079-0.259) and
NLR (difference between area: 0.279; 95% CI: 0.172-0.419) for the SYNTAX Score. Analysis
showed a strong correlation between these indices with SYNTAX Score >22 compared to low
scores <22 and that these also related to the LAD as an infarct artery. Multiple regression analysis
showed that diabetes mellitus, eGFR, Infarct-related artery left anterior descending (IRALAD),
MHR, MLR, and NLR were predictors of the severity of CAD in ACS patients based on
SYNTAX Score.
Conclusion: In ACS patients MHR, MLR, and NLR showed significant correlation with
SYNTAX score >22 which may be indicative of severity of disease. MHR is a better predictor of
the severity of CAD than MLR and NLR in ACS patients.
