Stroke Prevention and Management in Dialysis Patients

Introduction to Stroke Prevention

The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend targeting systolic BP <120 mmHg for dialysis patients who have suffered a stroke, with antiplatelet therapy, tight blood pressure control, and appropriate management of dialysis parameters to minimize hemodynamic instability 1
Dialysis patients have a higher risk of symptomatic intracranial hemorrhage and mortality with thrombolysis, and caution is advised when administering thrombolysis to CKD patients with acute ischemic stroke 2

Antiplatelet therapy is uniformly recommended for secondary stroke prevention in CKD patients, with aspirin as the preferred agent for dialysis patients with prior ischemic stroke 1
Thrombolysis may be considered in otherwise eligible hemodialysis patients, but with caution due to the higher risk of symptomatic intracranial hemorrhage and mortality 2

The KDIGO guidelines recommend targeting systolic BP <120 mmHg for dialysis patients, with use of renin-angiotensin system (RAS) blockers as first-line antihypertensive agents 1
Careful attention to volume control is essential for dialysis patients, with monitoring for post-dialytic drops in SBP and avoiding aggressive ultrafiltration immediately after stroke 1, 2

Statin therapy is recommended for CKD patients who have had a stroke, with continuation of statins if already taking them, and consideration of initiation only if LDL-C levels are very high (>3.8 mmol/L or 145 mg/dL) for dialysis patients 1

Anticoagulation decisions for dialysis patients with atrial fibrillation should be made in consultation with a nephrologist, with consideration of individualized stroke and bleeding risks 1, 3
Limited evidence exists for direct oral anticoagulants (DOACs) in dialysis patients, and warfarin has been associated with vascular calcification 1, 3

Hemodiafiltration may be considered as an alternative to conventional hemodialysis, with a 61% risk reduction in stroke compared to conventional hemodialysis 2
More frequent hemodialysis may be considered to improve BP control and reduce left ventricular mass, with careful volume control and hemodynamic stability during dialysis sessions 1, 2

Carotid revascularization may be considered in very high-risk dialysis patients with symptomatic carotid stenosis, but routine revascularization is not recommended for asymptomatic disease in dialysis patients 1
The presence of an embolic pattern of silent cerebral infarcts in carotid territory may influence decision-making regarding revascularization 1

For diabetic dialysis patients with eGFR >30 mL/min/1.73m², consideration of SGLT2 inhibitors may be beneficial 1
Lifestyle modifications, including smoking cessation, weight management, and regular exercise, are encouraged for all dialysis patients 1
Dual pathway blockade (antiplatelet plus low-dose anticoagulant) could be considered for secondary prevention, though evidence is limited 1
