That headline is misleading. Your feet can
sometimes show signs of circulation or heart problems, but there are not six specific foot symptoms that reliably predict a heart attack one month in advance.
Some foot/leg changes that deserve medical attention include:
-
Swelling in both feet or ankles — can occur with heart failure, but also with kidney, liver, vein, or medication-related problems.
-
Cold feet — persistent coldness can sometimes indicate poor circulation.
-
Pain or cramping when walking that improves with rest — can be a sign of peripheral artery disease (PAD), which is associated with higher cardiovascular risk.
-
Skin color changes — unusually pale, bluish, or reddish feet can indicate circulation problems.
-
Slow-healing sores on the feet — may indicate impaired blood flow, particularly in people with diabetes or PAD.
-
Numbness or weakness — can have many causes, including nerve problems, diabetes, or reduced circulation.
The important part
A heart attack can occur without any warning symptoms, and foot symptoms alone cannot predict that one is coming. More typical warning symptoms include chest pressure/pain, shortness of breath, sweating, nausea, unusual fatigue, or pain/discomfort spreading to the arm, back, neck, jaw, or upper abdomen.
If someone is experiencing new chest pressure, severe shortness of breath, fainting, or other possible heart-attack symptoms right now, seek emergency medical care immediately rather than waiting for foot symptoms to develop.
