| Summary: | INTRODUCTION[|]The importance of the lipid-related biomarkers, like neutrophil to high density lipoprotein cholesterol (HDL) ratio (NHR), monocyte to HDL ratio (MHR) and low density lipoprotein cholesterol (LDL) to HDL ratio (LHR), has been implicated in the pathological process of atherosclerosis. Our study was conducted to discuss and compare the predictive ability of the NHR, MHR and LHR in elderly patients with asymptomatic carotid stenosis(ACS).[¤]METHODS[|]Our study included 124 patients, aged ≥ 65 years, complained with dizziness and applied to our clinic from January 2010 to September 2020 and 125 healthy controls of similar age and gender. When blood samples were taken for white blood cell count and biochemical analysis; carotid artery Doppler ultrasonography was performed to define carotid stenosis.[¤]RESULTS[|]While NHR, MHR and LHR values were significantly higher in the patient group; a linear correlation was found between NHR, MHR and LHR values and the degree of carotid stenosis. In the ROC analysis performed to determine the cut-off values in detecting carotid stenosis, the area under the curve (AUC) for NHR was 0.68 and the cut-off point was 0.09; the AUC for MHR was 0.61, cut-off point was 0.01 and the AUC for LHR was 0.58 and the cut-off point was 1.61. [¤]DISCUSSION AND CONCLUSION[|]As a result, we revealed that NHR, MHR, and LHR ratios can be used with a higher sensitivity than using these values individually in detecting asymptomatic carotid stenosis in elderly patients. In addition, NHR value was found to be a more valuable biomarker in defining the presence and degree of carotid stenosis compared to MHR and LHR values.[¤]
