Summary

Early cerebral infarction deterioration is common, affecting over 40% of patients within 48 hours. High blood pressure, blood sugar, and carotid involvement predict this worsening, impacting long-term outcomes.

Area of Science:

  • Neurology
  • Internal Medicine
  • Clinical Research

Background:

  • Cerebral infarction (stroke) is a leading cause of disability.
  • Understanding early deterioration is crucial for timely intervention.
  • A defined risk profile for early infarct worsening is needed.

Purpose of the Study:

  • To identify risk factors for early neurological deterioration in acute cerebral infarction.
  • To establish a risk profile for patients with ischemic stroke within 8 hours of symptom onset.

Main Methods:

  • Prospective study of 98 patients with acute cerebral infarction (<8 hours).
  • Clinical data and radiological findings were collected.
  • Canadian Neurological Scale Score and Barthel index assessed over 3 months.

Main Results:

  • 40.8% of patients experienced deterioration within 48 hours.
  • Independent predictors of deterioration included high systolic blood pressure, elevated admission blood sugar, and carotid territory infarction.
  • Mortality was significantly higher in patients with infarct deterioration (35% vs. 8.6%).

Conclusions:

  • A significant proportion of acute cerebral infarction patients deteriorate early.
  • Specific clinical and radiological markers predict this deterioration.
  • Early infarct worsening is associated with increased mortality and reduced functional capacity.
