Insights
Statins may reduce perioperative complications in patients with high-grade carotid stenosis by stabilizing plaques and reducing inflammation. Preoperative statin use is increasingly supported for managing this high-risk condition.
Area of Science:
- Vascular Biology and Atherosclerosis
- Cerebrovascular Disease
- Pharmacology
Context:
- High-grade internal carotid artery stenosis is a primary cause of cerebral ischemia due to arterio-arterial emboli.
- Inflammatory processes drive atherosclerotic plaque development and destabilization, increasing thrombosis risk.
- Perioperative complications during carotid endarterectomy are a significant concern.
Purpose:
- To explore the role of inflammation in carotid stenosis and its link to perioperative risks.
- To evaluate the lipid-independent effects of statins, including plaque stabilization and improved cerebral autoregulation.
- To assess the evidence supporting preoperative statin administration in patients with high-grade carotid stenosis.
Summary:
- Inflammatory cells like macrophages contribute to carotid plaque instability via proinflammatory factors, matrix metalloproteinases, and tissue factor.
- Statins, beyond cholesterol reduction, demonstrate plaque-stabilizing properties and enhance cerebral autoregulation.
- Evidence suggests preoperative statins can mitigate risks associated with high-grade carotid stenosis and endarterectomy.
Impact:
- Highlights the therapeutic potential of statins in managing high-risk carotid artery disease.
- Informs clinical practice regarding the preoperative use of statins to improve patient outcomes.
- Underscores the importance of targeting inflammatory pathways in cerebrovascular disease management.
Abstract:
Arterio-arterial emboli originating from a high-grade stenosis of the internal carotid artery are a common cause for cerebral ischemias. Inflammatory processes are not only pivotal in the development of atherosclerotic vessel wall changes, but also for their clinical destabilization. Inflammatory cells, like macrophages, can turn a chronic high-grade carotid stenosis into a high-risk area for the development of arterial thromboses by way of a complex pathogenesis involving the elevation of proinflammatory factors, biosynthesis of collagen-degrading matrix metalloproteinases and expression of prothrombotic tissue factor. This process could affect the occurrence of perioperative complications during carotid endarterectomies. Statins are potent cholesterol-lowering agents. Among other lipid-independent effects, statins appear to play a significant role in preventing cardiovascular events. A number of studies have shown that statins possess plaque-stabilizing effects and that they improve cerebral autoregulation. A growing evidence supports the preoperative administration of statins in patients with high-grade stenoses of the internal carotid artery.
