Reproducibility of a new method to assess endothelial function by peripheral arterial volume

The assessment of endothelial function is crucial in understanding the progression of cardiovascular disease. It is important to have reliable and convenient non-invasive methods for evaluating endothelial function. Peripheral arterial volume (PAV) measurement at the fingertip is a novel approach, but there is limited data on its reproducibility. Hence, this study aims to evaluate the reproducibility of PAV measurement in a clinical setting.
