Insights

Hematologic indices, including monocyte to lymphocyte ratio (MLR) and mean corpuscular hemoglobin concentration (MCHC), can predict severe carotid artery disease. Elevated MLR and MCHC levels indicate a higher likelihood of collateral carotid stenosis, aiding in atherosclerosis assessment.

Area of Science:

  • Vascular Surgery
  • Hematology
  • Cardiovascular Disease

Background:

  • Carotid artery disease is a significant cause of ischemic stroke.
  • Biomarkers are crucial for predicting stroke progression and severity.
  • Severe carotid disease necessitates surgical intervention.

Purpose of the Study:

  • To compare hematologic indices in patients with severe carotid disease.
  • To identify predictive markers for collateral carotid stenosis.

Main Methods:

  • Retrospective study of 135 patients undergoing surgical carotid intervention.
  • Analysis of hematologic indices, including monocyte to lymphocyte ratio (MLR) and mean corpuscular hemoglobin concentration (MCHC).
  • Statistical analysis using Mann-Whitney test and logistic regression.

Main Results:

  • Significant differences in MLR and MCHC were found between patients with single and multiple (collateral) carotid diseases.
  • MLR > 0.3 (AUC=0.654) and MCHC > 21.6 (AUC=0.730) showed predictive value.
  • Logistic regression identified MLR > 0.3 (OR=6.19) and MCHC > 21.6 (OR=7.76) as significant predictors for collateral carotid stenosis.

Conclusions:

  • Elevated MLR and MCHC levels are valuable predictors of collateral carotid stenosis.
  • These hematologic indices can serve as accessible indicators of atherosclerosis severity.
  • MLR and MCHC may assist in risk stratification for patients with carotid artery disease.
