Stroke in Patients with Chronic Kidney Disease…: How do we Approach and Manage it?

Area of Science:

• Nephrology
• Neurology
• Cardiovascular Medicine

Background:

• Renal failure is a major risk factor for stroke, increasing incidence and mortality.
• Patients with chronic kidney disease (CKD), particularly those on dialysis, experience a 5-30 times higher stroke risk.
• CKD patients exhibit higher stroke case fatality rates, approaching 90%.

Purpose of the Study:

• To review the factors predisposing patients with CKD to stroke.
• To discuss preventive strategies for stroke in the CKD population.
• To outline the approach to managing stroke in patients with renal failure.

Main Methods:

• This article is a review of existing literature on stroke in CKD patients.
• It synthesizes information on risk factors, pathophysiology, and management strategies.
• The review examines the interplay of comorbidities, uremic toxins, dialysis-specific factors, and therapeutic interventions.

Main Results:

• Stroke risk in CKD is multifactorial, involving vascular comorbidities and renal failure-specific issues like malnutrition-inflammation-atherosclerosis.
• Hypertension, diabetes, old age, and prior cerebrovascular disease are key risk factors, with dialysis initiation being a high-risk period.
• Thrombolytic therapy carries increased hemorrhage risk, statins show no benefit in dialysis patients, and newer anticoagulants lack data in severe CKD.

Conclusions:

• Hypertension control and judicious antiplatelet use are primary stroke prevention strategies in CKD.
• Balancing antiplatelet/anticoagulant benefits against bleeding risks is critical, especially in dialysis cohorts.
• Caution is advised with anticoagulants in CKD due to potential risks like vascular calcification and lack of data in severe renal impairment.
