Imaging Studies for Cardiovascular System IV: CMRI

541
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Ischemic Stroke l: Introduction

44
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: Pathophysiology

54
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...

Summary

Chronic rhinosinusitis (CRS) is linked to ischemic stroke risk, particularly when frontal, ethmoid, or sphenoid sinuses are affected. This suggests targeted CRS surveillance for stroke prevention in at-risk individuals.

Area of Science:

  • Neurology
  • Otolaryngology
  • Radiology

Background:

  • Chronic rhinosinusitis (CRS) is an emerging independent risk factor for stroke.
  • The specific sinus involvement in the association between CRS and stroke remains underexplored.

Purpose of the Study:

  • To investigate the side- and sinus-specific relationship between CRS and ischemic stroke.
  • To identify specific sinuses associated with stroke laterality and patient demographics.

Main Methods:

  • Retrospective review of ischemic stroke patients at a tertiary center.
  • Diagnosis of CRS based on Lund-Mackay scoring (≥4) via CT or MRI.
  • Analysis of side- and sinus-specific correlations, including subgroup analyses by age.

Main Results:

  • CRS prevalence in ischemic stroke patients was 18.4%.
  • Significant correlations found between stroke side and affected frontal, ethmoid (anterior/posterior), and sphenoid sinuses.
  • No significant correlation between stroke side and maxillary sinus involvement.
  • A right-side correlation was observed in older patients (≥65 years).
  • Diabetes mellitus identified as an independent risk factor for CRS in stroke patients.

Conclusions:

  • CRS in specific sinuses (frontal, ethmoid, sphenoid) shows a directional relationship with ischemic stroke.
  • Findings support active CRS surveillance in individuals at high risk for ischemic stroke.
  • Sinus-specific analysis provides novel insights into the CRS-stroke association.
