Insights

Diabetic patients with ischemic stroke show distinct patterns, including more atherothrombotic and lacunar strokes. Early clinical factors predict in-hospital mortality, aiding prognosis assessment.

Area of Science:

  • Neurology
  • Cardiology
  • Endocrinology

Background:

  • Ischemic stroke characteristics and prognostic features differ between diabetic and non-diabetic patients.
  • Identifying independent predictors of in-hospital mortality in diabetic ischemic stroke patients is crucial.

Purpose of the Study:

  • To compare ischemic stroke characteristics and prognosis in patients with and without diabetes.
  • To determine independent predictors of in-hospital mortality in diabetic ischemic stroke patients.

Main Methods:

  • Prospective stroke registry of 1,840 patients over 12 years.
  • Comparison of demographic data, risk factors, clinical events, stroke subtypes, neuroimaging, and outcomes between diabetic and non-diabetic groups.
  • Multivariate analysis to assess predictors of in-hospital mortality in diabetic patients.

Main Results:

  • Diabetic patients had more atherothrombotic stroke (41.2%) and lacunar infarction (35.1%) than non-diabetic patients.
  • In-hospital mortality rates were similar: 12.5% for diabetic and 14.6% for non-diabetic patients.
  • Independent predictors of ischemic stroke in diabetics included ischemic heart disease, hyperlipidemia, advanced age, and specific stroke types; mortality predictors included age, consciousness level, nephropathy, heart failure, and atrial fibrillation.

Conclusions:

  • Ischemic stroke presents differently in diabetic patients, with a higher prevalence of atherothrombotic and lacunar infarcts.
  • Early clinical factors indicating stroke severity are key predictors of in-hospital mortality.
  • These findings can assist clinicians in more accurate prognosis assessment for diabetic stroke patients.

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Ischemic Stroke ll: Pathophysiology01:15

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...

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
