Another common symptom is swelling in the feet and ankles, often resulting from fluid retention caused by heart failure, especially after long periods of sitting or standing. Discoloration—such as blue, purple, or pale skin—may suggest inadequate oxygen or reduced blood flow reaching the extremities.

Numbness or tingling sensations can also be linked to reduced circulation and may worsen during activity, pointing to peripheral artery disease (PAD), a condition closely tied to heart disease. Similarly, sores or wounds on the feet that don’t heal could signal chronic poor circulation, particularly dangerous for individuals with diabetes. Another serious symptom is pain while walking (claudication), which involves cramping in the feet or calves and is a strong predictor of cardiovascular issues.

These symptoms don’t guarantee a heart attack is imminent, but they strongly
