Key Points

This research investigates the relationship between VWF, ADAMTS13, and major adverse limb events (MALE) in peripheral artery disease (PAD).
Analyzed baseline VWF levels and VWF/ADAMTS13 ratios in a PAD cohort.
Examined associations with subsequent major adverse limb events (MALE).
Compared findings to existing literature on adverse cardiovascular events.
Lower baseline VWF levels were associated with higher rates of MALE.
VWF/ADAMTS13 ratios also showed similar inverse correlation with MALE.
Findings challenge previous assumptions about VWF levels and vascular disease outcomes.

Abstract

Contrary to our original hypothesis, lower baseline VWF levels and VWF/ADAMTS13 ratios were associated with subsequent MALE in this high-risk PAD cohort, which may reflect increased VWF consumption in severe, diffuse atherosclerosis. This study contributes to the limited literature on VWF and ADAMTS13 in PAD in relation to MALE, as previous research has largely focused on major adverse cardiovascular events. Larger studies in patients with similar risk profiles are required to validate these findings.
