Background:

Permanent hemodialysis access, while beneficial, presents risks like flow disturbances and infection.
These complications can potentially lead to impaired cardiac function.
The specific relationship between arteriovenous access flow and cardiac function in hemodialysis patients remains unclear.

Purpose of the Study:

To analyze the relationship between artificial arteriovenous access flow and left and right ventricular function.
To investigate cardiac function in patients with chronic kidney disease (CKD) undergoing hemodialysis.

Main Methods:

Cross-sectional study with consecutive sampling of 47 CKD patients undergoing hemodialysis.
Doppler ultrasound used to measure arteriovenous access flow.
Transthoracic echocardiography employed to assess left and right ventricular function.

Main Results:

55.3% of patients exhibited high arteriovenous access flow.
Patients with high access flow showed significantly lower left ventricular ejection fraction compared to the non-high-flow group (p < 0.05).
The high-flow group also demonstrated significantly lower right ventricle fractional area changes (p < 0.05).

Conclusions:

Arteriovenous access flow, measured by Doppler ultrasonography, is significantly associated with impaired left and right ventricular systolic function.
Echocardiographic parameters indicate a link between high access flow and reduced cardiac performance in hemodialysis patients.
