That claim is misleading. Your feet can sometimes show signs of circulation or fluid problems, but there are no six specific foot symptoms that reliably predict a heart attack one month in advance.
Some foot/leg changes that deserve medical attention include:
- New or persistent swelling in both feet or ankles, which can occur with fluid retention and sometimes heart failure.
- Cold feet or legs, particularly with pain or color changes, which may indicate poor circulation.
- Pain or cramping in the legs when walking that improves with rest, which can occur with peripheral artery disease.
- Sudden swelling, warmth, redness, or pain in one leg, which can be a sign of a blood clot and needs prompt medical assessment.
- Skin or nail changes associated with poor circulation, especially when accompanied by pain or wounds that don’t heal.
However, these findings do not mean a heart attack is about to happen.
The symptoms you shouldn’t wait on
Heart-attack warning symptoms are more commonly chest pressure/pain, shortness of breath, sweating, nausea, unusual weakness, or pain/discomfort in the arm, shoulder, back, neck or jaw. Symptoms can be less typical in women, older adults, and people with diabetes.
If you or someone else has new chest pressure/pain, severe shortness of breath, fainting, or other symptoms suggesting a heart attack, seek emergency medical care immediately rather than waiting for foot symptoms to develop.
