In assessing a patient with coronary artery disease and diabetes, what physical examination finding could suggest peripheral vascular disease?

Weak pedal pulses are indicative of peripheral vascular disease, particularly in patients with existing conditions like coronary artery disease and diabetes. This is because these conditions can lead to atherosclerosis, where the arteries become narrowed or blocked, reducing blood flow to the extremities. The pedal pulses, located at the dorsum of the foot or behind the medial malleolus, are often assessed during a physical examination to evaluate circulation in the lower limbs. When these pulses are weak or diminished, it suggests inadequate blood flow, which is characteristic of peripheral vascular disease.

Other physical findings could also be associated with vascular issues; however, weak pedal pulses specifically indicate a significant impairment in blood flow. This finding is crucial in the clinical assessment as it could guide further investigations and management strategies in patients with peripheral vascular disease.
