Hemodialysis vascular access affects heart function and outcomes: Tips for choosing the right access for the...

Area of Science:

• Nephrology
• Cardiology
• Vascular Surgery

Background:

• Chronic kidney disease (CKD) significantly increases cardiovascular morbidity and mortality.
• Arteriovenous (AV) fistula offers superior outcomes for hemodialysis vascular access but can affect cardiac function.
• Understanding the cardiovascular impact of AV access is critical for managing dialysis patients.

Purpose of the Study:

• To review the cardiovascular hemodynamics in dialysis patients related to AV access.
• To explore the effects of AV access on heart function, including high-output heart failure and pulmonary hypertension.
• To provide guidance on vascular access selection and management in CKD patients with cardiac conditions.

Main Methods:

• Literature review focusing on cardiovascular hemodynamics in dialysis patients.
• Analysis of AV access impact on cardiac function and clinical status.
• Examination of alternative dialysis modalities and vascular access considerations.

Main Results:

• AV access, while beneficial for survival, can lead to adverse cardiac events like high-output heart failure.
• Peritoneal dialysis may be preferable in severe heart failure cases.
• Management strategies for AV access in kidney transplant recipients and patients switching modalities are discussed.

Conclusions:

• Careful consideration of AV access type and management is essential for dialysis patients, especially those with pre-existing cardiac conditions.
• Individualized vascular access selection is crucial for optimizing cardiac health in CKD patients.
• The interplay between vascular access, cardiac health, and interventions like cardiac surgery requires integrated management.
