Summary

Elevated erythrocyte sedimentation rate (ESR), hematocrit (HCT), and white blood cell (WBC) counts predict higher 30-day stroke fatality. These blood markers are key indicators for stroke outcomes in patients.

Area of Science:

  • Neurology
  • Hematology
  • Epidemiology

Background:

  • Stroke is a leading cause of mortality and disability worldwide.
  • Identifying predictive factors for stroke outcomes is crucial for patient management.
  • Hematological parameters and inflammatory markers are increasingly recognized for their prognostic value in stroke.

Purpose of the Study:

  • To investigate the association between various hematological parameters and glucose concentration with 30-day case fatality in stroke patients.
  • To identify independent predictors of short-term mortality following a stroke event.

Main Methods:

  • A prospective, population-based study involving 345 stroke patients admitted within 72 hours of onset.
  • Analysis of hematocrit (HCT), hemoglobin (Hgb), red blood cells (RBC), mean cell volume (MCV), platelet count, erythrocyte sedimentation rate (ESR), white blood cells (WBC), and glucose concentration.

  • Logistic regression analysis was employed to determine independent predictors of 30-day case fatality.

    • Main Results:

    • Patients who died within 30 days exhibited significantly higher mean values for ESR, WBC, HCT, and glucose concentration compared to survivors.
    • Logistic regression identified ESR, HCT, and WBC as independent predictors of 30-day stroke fatality.
    • The odds ratios for ESR, HCT, and WBC were 1.006, 1.04, and 1.03, respectively.

    Conclusions:

    • Elevated ESR, HCT, and WBC are significant independent predictors of 30-day case fatality in stroke patients.
    • While glucose levels were higher in non-survivors, they did not emerge as an independent predictor after adjusting for neurological deficit severity.
    • These hematological markers can aid in risk stratification and early identification of high-risk stroke patients.
