Insights

In elderly stroke patients, 19% had a patent foramen ovale (PFO). PFO presence was not strongly linked to other stroke risk factors in this group.

Area of Science:

  • Cardiology
  • Neurology
  • Geriatrics

Background:

  • Cerebral infarction is a common cause of stroke in the elderly.
  • Patent foramen ovale (PFO) is a potential, yet debated, risk factor for stroke.
  • Identifying PFO incidence and associated risk factors in this demographic is crucial for stroke prevention.

Purpose of the Study:

  • To determine the incidence of echocardiographically detected PFO in elderly patients with cerebral infarction.
  • To assess the association between PFO and other established stroke risk factors in this population.

Main Methods:

  • Transesophageal echocardiography was used to assess 43 consecutive patients aged 65 years or older admitted with cerebral infarction.
  • Patients were evaluated for the presence of PFO and other stroke risk factors, including atrial fibrillation and diabetes mellitus.

Main Results:

  • A patent foramen ovale (PFO) was detected in 8 out of 43 patients (19%).
  • Among patients with PFO, 50% had other stroke risk factors (atrial fibrillation or diabetes).
  • In patients without PFO (81%), a higher prevalence of risk factors was observed (83%), with many having multiple risk factors.

Conclusions:

  • The incidence of PFO in elderly patients with cerebral infarction is 19%.
  • The presence of PFO in this study was not strongly associated with other common stroke risk factors.
  • Further research is needed to clarify the role of PFO in elderly stroke patients, especially in the context of other comorbidities.

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: 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...
