What this trial studies

This observational study investigates the effects of various anticoagulant and antiplatelet drug combinations on patients with Peripheral Arterial Disease (PAD) following surgical revascularization. Patients aged 50 and older with symptomatic PAD will be monitored for Major Adverse Cardiovascular Events (MACE) and Major Adverse Limb Events (MALE) at 1, 6, and 12 months post-operation. The study aims to analyze the type, dosage, and duration of the medications administered to determine their impact on patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 50 and older with symptomatic PAD who have undergone successful revascularization.

Not a fit: Patients with acute limb ischemia, significant tissue defects, or those requiring systemic anticoagulation after revascularization may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for preventing serious cardiovascular and limb-related complications in PAD patients after surgery.

How similar studies have performed: While similar studies have explored anticoagulant effects in cardiovascular contexts, this specific approach in PAD patients post-revascularization is relatively novel.
