Summary

Early stroke deterioration stems from brain injury, while later decline is linked to systemic issues. Initial neurological deficit severity predicts worsening in acute ischemic stroke patients.

Area of Science:

  • Neurology
  • Stroke Medicine
  • Clinical Neuroscience

Background:

  • Deterioration following acute ischemic stroke can be neurological or systemic.
  • Understanding the origins of stroke progression is crucial for patient management.

Purpose of the Study:

  • To investigate the causes of clinical deterioration in patients with first-ever ischemic stroke (FIS).
  • To identify predictors of stroke deterioration.

Main Methods:

  • 442 patients with FIS were assessed using the Unified Neurological Stroke Scale (UNSS).
  • Assessments were conducted at admission, on hospitalization days 1, 2, 3, and before discharge.

Main Results:

  • 16.1% of patients (71/442) deteriorated during hospitalization, with 94.4% experiencing early worsening (

  • Cerebral causes predominated in early deterioration (80.3%), while late deterioration was exclusively systemic (100%).
  • The initial UNSS score was the sole significant independent predictor of stroke deterioration (p < 0.0001).

    • Conclusions:

    • Early deterioration in FIS is linked to infarct-inherent mechanisms.
    • Late deterioration is primarily driven by systemic factors.
    • Initial neurological deficit severity predicts subsequent decline in stroke patients.
