[Hemorrhagic infarct of the brain during cardiogenic shock]
Insights
Myocardial infarction complicated by cardiogenic shock can lead to hemorrhagic brain infarction. This is likely due to combined metabolic and microcirculatory issues, alongside artery stenosis.
Area of Science:
- Neurology
- Cardiology
- Pathology
Context:
- Myocardial infarction (MI) is a leading cause of mortality.
- Cardiogenic shock (CS) significantly increases mortality in MI patients.
- Cerebral complications, including hemorrhagic brain infarction, are severe outcomes in CS.
Purpose:
- To investigate the potential mechanisms underlying hemorrhagic brain infarction in patients with myocardial infarction complicated by severe cardiogenic shock.
- To analyze postmortem findings of the brain and its vasculature in affected individuals.
Summary:
- Postmortem examination of the brain and major cerebral arteries, including the Circle of Willis, was conducted.
- Findings suggest a combined mechanism involving metabolic disturbances and microcirculatory dysfunction associated with cardiogenic shock.
- Stenosing atherosclerotic processes, particularly in intracranial arteries supplying the brain, contribute to this complication.
Impact:
- Provides insights into the pathophysiology of cerebral complications in cardiogenic shock.
- Highlights the interplay between cardiac events, shock, and cerebrovascular integrity.
- Informs potential therapeutic strategies targeting metabolic and microcirculatory pathways to prevent brain infarction in high-risk patients.
Abstract:
The paper deals with the possible mechanism in the development of a hemorrhagic brain infarction during myocardial infarction, complicated by a cardiogenic shock of the III degree. The results of a postmortal study of the brain, its major arteries, as well as the vessels of the Willis circle, permit to assume that the mechanism of realization of this cerebral vascular complication is in a joint metabolic and microcirculatory disorders accompanying the shock. Besides, there is also a stenosing atherosclerotic process, with prevalent lesion of the intracranial part of the magistral arteries, supplying the brain.
