When it comes to heart problems, most people think of chest pain, shortness of breath, or fatigue as warning signs. But your feet may also hold important clues. Because the heart and blood vessels are responsible for circulating oxygen-rich blood throughout the body, changes in the feet and ankles can reflect cardiovascular dysfunction.
These symptoms are not definitive proof of a heart attack or heart disease, but they can serve as early warning signs—sometimes appearing weeks before more serious cardiac events. Paying attention to your feet may help prompt timely medical evaluation and even prevent more severe complications.
Swelling in the Feet and Ankles
Swelling (edema) in the lower extremities is another common red flag. When the heart struggles to pump effectively, blood can pool in the veins and cause fluid to leak into surrounding tissues. The result is noticeable puffiness in the feet, ankles, or even the legs. People often observe this swelling at the end of the day, after standing or sitting for long periods. While swelling can also be caused by other conditions, such as kidney or liver problems, it is a classic symptom of heart failure.
Discoloration of the Skin
Changes in skin color are another subtle but important sign. Blue or purple tones in the feet may point to a lack of oxygen-rich blood reaching the area. Pale skin can suggest reduced blood flow as well. These changes indicate that circulation is compromised, and if left unaddressed, tissues in the extremities may not receive the oxygen they need to stay healthy.
Numbness and Tingling
Pins-and-needles sensations or persistent numbness in the feet can be linked to peripheral artery disease (PAD). PAD occurs when fatty deposits build up in the arteries that supply blood to the legs and feet, restricting circulation. Since PAD is closely associated with heart disease and stroke, these symptoms should not be overlooked. Numbness and tingling that worsen during activity are particularly concerning, as they indicate blood flow is struggling to keep up with the body’s demand.
