Prognostic Value of Blood Parameters in Patients Diagnosed with Ischemic and Hemorrhagic Cerebrovascular Events

INTRODUCTION Cerebral infarction is defined as an acute neurological injury stroke that occurs as a result of intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). 80-85% of stroke cases are ischemic group. Hemorrhagic stroke is responsible for approximately 10-30% of these cases. Studies have shown that the inflammatory response that occurs exacerbates ischemic brain injury and neurological dysfunction. MATERIALS AND METHODS Patients who were admitted to a tertiary state hospital in Istanbul in the last six months and diagnosed with stroke were retrospectively analyzed. Blood samples taken at the time of admission of 116 patients with stroke diagnosed in the study were examined and neutrophil and lymphocyte values in the complete blood count were used in the study. Neutrophil/Lymphocyte ratios (NLR) were calculated by subtracting these values. Hospitalization times of the patients were recorded. The correlation of NLR values of the cases with the length of hospital stay was examined. RESULTS Of the 116 patients included in the study, 100 had ischemic stroke and 16 had hemorrhagic stroke. Of the cases examined, 63 were male and 53 were female. The mean age was 71.6±11.6 years. There was no statistically significant difference between hemorrhagic stroke and ischemic stroke groups in terms of age and gender. We examined the correlation between the length of hospital stay and NLR values of the patients. We found that there was no statistically significant correlation between length of stay and NLR in ischemic stroke and hemorrhagic stroke patient groups. Likewise, when we examined the length of hospitalization and NLR levels, we showed that there was no weak and statistically significant correlation. CONCLUSION Although there are many studies in the literature showing that high neutrophil and low lymphocyte values have a negative effect on mortality and morbidity, there are also studies that have not been shown to have an effect as in our study.
