Dialysis fistulas and cardiac failure
Acta Medica Scandinavica
|January 1, 1978
Summary
Haemodialysis fistulas can contribute to cardiac failure, especially in patients with reduced cardiac reserve. Surgical reduction of fistula blood flow may improve cardiac function in affected individuals.
Area of Science:
- Nephrology
- Cardiology
- Vascular Surgery
Background:
- Dialysis access via arteriovenous fistulas is standard for haemodialysis.
- High fistula blood flow has been anecdotally linked to cardiac complications.
Observation:
- Six patients with haemodialysis fistulas and cardiac failure were studied.
- One patient underwent fistula closure, showing significant cardiac improvement.
Findings:
- Haemodialysis fistulas are unlikely to cause cardiac failure independently.
- Fistulas may exacerbate pre-existing cardiac conditions or contribute to failure when cardiac reserve is diminished.
Implications:
- Surgical management of fistula flow should be considered in patients with cardiac compromise.
- Further research is warranted to elucidate the precise mechanisms and patient selection for fistula revision.
