Why the study?
Does the Arteriograph device provide reproducible measurements and agree with SphygmoCor for assessing arterial stiffness and central blood pressure in patients with type 2 diabetes?
Does the Arteriograph device provide reproducible measurements and agree with SphygmoCor for assessing arterial stiffness and central blood pressure in patients with type 2 diabetes?
This study evaluates the reproducibility and agreement of the Arteriograph device compared to the SphygmoCor system for measuring arterial stiffness and central blood pressure in patients with type 2 diabetes.
Arteriograph reproducibility in T2D appears acceptable; leaves open agreement with SphygmoCor and clinical adoption.
Background: The Arteriograph is a cuff-based oscillometric device for non-invasive assessment of central systolic blood pressure (cSBP), aortic augmentation index (Aix) and aortic pulse wave velocity (PWV).Reproducibility of Arteriograph measurements and the agreement with SphygmoCor in diabetic patients has never been assessed.Methods: We compared Arteriograph reproducibility and agreement with SphygmoCor with data from two study populations: Study 1 (n Z 17) was conducted in a research laboratory and Study 2 (n Z 19) in a catheter lab.SphygmoCor PWV data was only available in study 1.Results: Reproducibility: Mean differences (AEStandard deviation of the difference (SDD)) between duplicate cSBP, Aix and PWV Arteriograph measurements were À0.6 AE 6.6 mmHg,
