Summary
Hyperglycemia (high blood sugar) after ischemic stroke increases mortality. Achieving normal blood glucose levels within 48 hours significantly improves survival rates for stroke patients.
Area of Science:
- Neurology
- Endocrinology
- Critical Care Medicine
Background:
- Hyperglycemia following cerebral ischemia is linked to increased brain injury and poorer outcomes in stroke patients.
- Effective glycemic control is crucial for managing acute stroke and improving patient survival.
Purpose of the Study:
- To investigate the impact of initial blood glucose levels and glycemic control on mortality in patients with acute ischemic stroke.
- To determine if normalizing blood glucose levels during hospitalization improves survival rates.
Main Methods:
- A retrospective study analyzed data from patients diagnosed with ischemic stroke over a 40-month period.
- Patients were categorized based on admission blood glucose levels and glycemic control within the first 48 hours of hospitalization.
Main Results:
- Admission hyperglycemia (blood glucose ≥ 130 mg/dL) was associated with a 3.15-fold increased mortality risk.
- Persistent hyperglycemia during the first 48 hours showed an even higher mortality risk (OR = 6.54).
- Glycemic control, normalizing blood glucose to < 130 mg/dL, resulted in a 4.6-fold decrease in mortality risk and was an independent determinant of survival.
Conclusions:
- Admission hyperglycemia is a significant predictor of worse outcomes in acute ischemic stroke.
- Prompt normalization of blood glucose levels within 48 hours of hospitalization offers a substantial survival benefit for patients with thromboembolic stroke.

Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Hypoglycemia and Glucagon
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
