Insights

Elevated plasma homocysteine levels are linked to an increased risk of ischemic stroke in elderly Japanese individuals. This finding supports previous research in Western populations, highlighting homocysteine as a significant risk factor.

Area of Science:

  • Neurology
  • Cardiovascular Science
  • Clinical Chemistry

Background:

  • Ischemic stroke is a leading cause of disability and mortality.
  • Atherosclerosis is a primary risk factor for ischemic stroke.
  • Plasma homocysteine is a recognized risk factor for atherosclerosis and cardiovascular events.

Purpose of the Study:

  • To investigate the association between plasma homocysteine concentrations and ischemic stroke.
  • To determine if this association holds true in an elderly Japanese population.

Main Methods:

  • A case-control study involving 91 elderly Japanese in-patients.
  • Plasma homocysteine levels were measured using high-performance liquid chromatography.
  • Logistic regression analysis was used to adjust for other risk factors.

Main Results:

  • Patients with ischemic stroke had significantly higher plasma homocysteine levels.
  • Odds ratios for ischemic stroke increased with higher homocysteine concentrations.
  • Adjusted analysis confirmed a significant association between elevated homocysteine and ischemic stroke risk.

Conclusions:

  • Elevated plasma homocysteine is a significant risk factor for ischemic stroke in the elderly Japanese.
  • The findings corroborate the association observed in Western populations.
  • Plasma homocysteine measurement may aid in stroke risk assessment.

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
Ischemic Stroke l: Introduction01:15

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...
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...

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
