A Thrombotic Stroke Model Based On Transient Cerebral Hypoxia-ischemia
Published on: August 18, 2015
Insights
Cardiogenic brain embolism, often from ischemic heart disease, presents suddenly with neurological symptoms. Early anticoagulant therapy may improve outcomes by preventing further clots.
Area of Science:
- Neurology
- Cardiology
- Radiology
Context:
- Cardiogenic brain embolism is a significant cause of stroke.
- Understanding its origins, presentation, and outcomes is crucial for patient management.
Purpose:
- To analyze the symptoms, diagnosis, prognosis, and therapy of 135 cases of cardiogenic brain embolism.
- To identify common cardiac sources and neurological manifestations.
Summary:
- Ischemic heart disease with atrial fibrillation was the most frequent cause, followed by valvular heart disease, myocardial infarction, and carditis.
- Sudden onset of neurological symptoms, often in the morning, characterized presentations. Initial loss of consciousness and seizures were poor prognostic indicators.
- Angiographic findings included occlusions in the internal carotid artery and middle cerebral artery branches. Computed tomography (CT) and lumbar puncture were not diagnostic.
Impact:
- Mortality was 22%, with 34% experiencing significant neurological deficits, highlighting the serious prognosis.
- Recommended cardiologic evaluations include chest X-ray, long-term electrocardiogram, and echocardiography.
- Early anticoagulant therapy, if no cerebral hemorrhage is present on CT, may prevent re-embolization and improve outcomes.
Abstract:
135 cases of cardiogenic emboli to the brain are reported in view of symptoms, diagnosis, prognosis and therapy. Brain embolism occurred most often in ischemic heart disease with atrial fibrillation, followed by valvular heart disease, myocardial infarction and carditis. Usually there was a sudden onset of neurological symptoms during the morning hours. Initial lapses of consciousness were a bad prognostic sign--they appeared as well as seizures more often in embolic than in thrombotic brain infarctions. The clearly higher incidence of emboli to the left cerebral hemisphere has anatomical reasons. Angiographic findings depend on the time of examination; common are occlusions of the supraclinoid portion of the internal carotid artery, media-occlusions at the trifurcation, media-branch-occlusions and disturbed middle cerebral blood flow. CT and lumbar puncture do not support the diagnosis. Cardiologic examination should include X-ray of the chest, long time electrocardiogram and echocardiography. In view of a mortality of 22 per cent and major neurological residual symptoms in 34 percent the prognosis of brain embolism is serious. Early anticoagulant therapy in the absence of brain hemorrhage in CT seems to improve the prognosis by preventing reembolization.
