Flow chart for patients with Aortic stenosis according to flow-gradient patterns.

Baseline characteristics for non-PAD and PAD patients.

Resting Flow (RF), Peak Flow (PF), and Time-to-peak flow (tPF) in non-PAD and PAD patients.
Table 2.
Resting flow and reactive hyperaemia values (PF and tPF) in non-PAD and PAD patients.
Fig 4.
ROC curves for Peak Flow at 5 seconds and Time-to-peak flow in patients without severe aortic stenosis (AS).
The curves show the predictive potential of PF at 5 seconds (solid line) and tPF (dashed line) variables with respect to PAD in patients without AS. PF at 5 seconds and tPF correlated better with ABPI in patients without AS.
Fig 5.
ROC curves for Peak Flow at 5 seconds and Time-to-peak flow in patients with severe aortic stenosis (AS).
The curves show the predictive potential of PF at 5 seconds (solid line) and tPF (dashed line) variables with respect to PAD in patients with AS. PF at 5 seconds correlated well with ABPI; the tPF correlate less with ABPI in this group.
Fig 6.
Scatter plot for the correlation between tPF (vertical axis) and ABPI (horizontal axis).
There is a significant correlation between tPF in PAD patients with ABPI values less than 0.7 (dash-lined box in the plot).

Sensitivity, specificity, positiv predictive and negative predictive values of SGP-RH parameters (RF, PF at 5sec and tPF) in PAD patients.
Fig 7.
Correlation between AVA and tPF in patients with AS.
The scatter plot shows a positive trend between AVA reduction and prolonged tPF in patients with AS.
