Changes in blood filterability in cerebrovascular accidents

Summary
Blood filterability changes indicate stroke severity and prognosis. Deterioration worsens with fever, improving in recovering patients, offering therapeutic targets for cerebrovascular accidents (CVA).
Area of Science:
- Neuroscience
- Hematology
- Critical Care Medicine
Background:
- Acute cerebrovascular accidents (CVA) involve hemorheological changes impacting cerebral blood flow.
- Factors like increased hematocrit, blood viscosity, and impaired red cell deformability contribute to a prethrombotic state.
- These microcirculatory changes are critical in CVA severity and prognosis.
Purpose of the Study:
- To investigate the prognostic value of blood filterability in patients with acute cerebrovascular accidents (CVA).
- To correlate hemorheological factors with CVA severity and patient outcomes.
- To assess the impact of fever on blood filterability in CVA patients.
Main Methods:
- Red cell filterability was studied in 100 severe and 52 moderate CVA patients compared to controls.
- Blood filtration was monitored up to day 8 post-CVA.
- Comparison of filterability between febrile and non-febrile CVA patients.
Main Results:
- Deteriorated blood filterability was observed in CVA patients, worsening up to day 8.
- Recovering patients showed improvement in filtration after day 8.
- Febrile patients exhibited significantly greater filterability deterioration than non-febrile patients.
Conclusions:
- Blood filterability serves as a significant indicator of severity and prognosis in acute cerebrovascular accidents (CVA).
- Monitoring blood filtration aids in predicting patient recovery and outcomes.
- Therapeutic strategies like normovolemic hemodilution and specific drugs may improve hemorheological parameters in CVA.
