Key result
The Arteriograph device showed no significant correlation with the validated PulsePen tonometer for measuring pulse wave velocity (R=0.173, p=0.097) and lacked prognostic value for CV mortality.
Why the study?
Does the Arteriograph device provide valid measurements of arterial stiffness compared to the PulsePen tonometer in patients on maintenance hemodialysis?
Observational (n=98)

Effect estimate: R 0.173
p-value: p=0.097
The Arteriograph device has limited validity for determining pulse wave velocity and predicting cardiovascular mortality in hemodialysis patients compared to the validated PulsePen tonometer.
No takes yet. Share an insight, caveat, or question.
Arteriograph lacks reliability for PWV assessment in hemodialysis; leaves open need for device validation before any clinical use.
Nemcsik et al. (2009) conducted an observational in Maintenance hemodialysis (n=98). Arteriograph device vs. PulsePen tonometer was evaluated on Correlation of pulse wave velocity (PWV) measurements between devices (R 0.173, p=0.097). The Arteriograph device showed no significant correlation with the validated PulsePen tonometer for measuring pulse wave velocity (R=0.173, p=0.097) and lacked prognostic value for CV mortality.
