Summary

Transient hyperglycemia in nondiabetic stroke patients indicates poorer outcomes and higher mortality, similar to diabetes mellitus, but is not an independent predictor of 1-year mortality.

Area of Science:

  • Neurology
  • Endocrinology
  • Clinical Medicine

Background:

  • Glucose derangement is common in ischemic stroke.
  • Its prognostic significance in nondiabetic patients requires further investigation.

Purpose of the Study:

  • To investigate glucose abnormalities and their prognostic value in nondiabetic ischemic stroke patients.
  • To assess short- and long-term outcomes, including mortality and functional capacity.

Main Methods:

  • Prospective study of 262 nondiabetic ischemic stroke patients.
  • Glucose levels monitored serially post-stroke; stroke severity assessed using Scandinavian Stroke Scale (SSS).
  • Outcomes measured at 30 days (mortality, Barthel Index, Rankin Scale) and 1-year survival analyzed via Kaplan-Meier and Cox regression.

Main Results:

  • Transient hyperglycemia affected 36.3% of patients.
  • Patients with transient hyperglycemia showed lower SSS scores, larger infarcts, and higher 30-day mortality than normoglycemic patients.
  • One-year mortality was similar in transient hyperglycemia and diabetes mellitus groups, and significantly higher than in normoglycemia.

Conclusions:

  • Transient hyperglycemia in nondiabetic ischemic stroke patients is associated with worse short-term outcomes and increased mortality.
  • While not an independent predictor of 1-year mortality, it carries a similar prognosis to diabetes mellitus.
