Peripheral Artery Disease (PAD) Risk Factors Study Guide

This guide provides a comprehensive overview of Peripheral Artery Disease (PAD), covering its pathophysiology, risk factors, clinical manifestations, diagnostic methods, and treatment options. Learn to recognize the signs and symptoms of PAD, including intermittent claudication, rest pain, and skin changes, and understand the importance of timely diagnosis and management.
