Chronic kidney disease in the pathogenesis of acute ischemic stroke

Area of Science:

• Nephrology
• Neurology
• Vascular Medicine

Background:

• Chronic kidney disease (CKD) is a prevalent condition with significant implications for cerebrovascular health.
• Both thrombotic and hemorrhagic stroke complications are common in CKD patients, with ischemic strokes being more frequent.
• Early-stage CKD, though often asymptomatic, initiates pathogenic processes affecting the endothelium and vasculature.

Purpose of the Study:

• To review the mechanisms linking chronic kidney disease to stroke.
• To elucidate how CKD influences stroke pathogenesis, outcomes, and treatment eligibility.

Main Methods:

• This review synthesizes existing evidence on the pathophysiological links between CKD and cerebrovascular disease.
• Mechanisms discussed include inflammation, oxidative stress, uremic toxins, vascular calcification, and the exacerbation of traditional vascular risk factors.

Main Results:

• CKD promotes endothelial dysfunction and vascular damage through multiple pathways.
• Uremic toxins can cross the blood-brain barrier, contributing to cognitive impairment and neurodegeneration.
• CKD exacerbates stroke risk factors like hypertension and atherosclerosis, negatively impacting stroke recovery.

Conclusions:

• Chronic kidney disease presents a significant, independent risk factor for stroke.
• Understanding these mechanisms is crucial for developing targeted interventions to mitigate cerebrovascular complications in CKD patients.
