Warning Signs in the Feet That May Reflect Cardiovascular Risk

Both the ADA and AHA emphasize that early recognition of vascular and neurological symptoms is essential.

Watch for:

• Cold feet or decreased temperature

May indicate reduced arterial blood flow.

• Swelling in ankles or feet

According to the AHA, persistent swelling (edema) can be a sign of heart failure.

• Leg pain during walking (claudication)

A classic PAD symptom described in AHA guidelines — pain that improves with rest.

• Slow-healing wounds

The ADA recommends immediate evaluation of any foot ulcer that does not improve within two weeks.

• Skin discoloration (pale, bluish, or reddish tone)

May signal compromised circulation.

The Compounded Risk

The ADA reports that people with diabetes are at significantly increased risk for lower-extremity amputation, particularly when peripheral neuropathy and PAD coexist.

The AHA further states that PAD is not just a leg problem — it is a marker of widespread atherosclerosis and increases the risk of heart attack and stroke.

This means that foot symptoms may indicate broader cardiovascular disease.
