3. Discoloration (blue, purple, or pale feet)
A bluish or purple tint can indicate low oxygen supply.
Pale or flat feet can indicate improved circulation.
4. Numbness or tingling
Poor circulation can lead to tingling or numbness.
This may worsen with increased activity and improve at rest—a possible sign of peripheral arterial disease (PAD), which is often associated with heart disease.
5. Wounds or wounds that don’t heal
Poor circulation can prevent the body from healing even minor cuts.
Chronic ulcers or slow-healing wounds on the feet are a warning sign, especially for people with diabetes.
6. Pain when walking (limping)
Pain or cramps in the feet or calves when walking can indicate PAD.
It is a reliable indicator of future cardiovascular events, including heart attacks.
❗ Important note:
These signs do not always mean that a heart attack is imminent, but they indicate that your cardiovascular system may be compromised.
✅ What to do if you notice these symptoms:
– See a doctor immediately, especially if the symptoms are new or worsening.
– Watch for other warning signs of a heart attack, such as chest pain, shortness of breath, fatigue, or dizziness.
– Get your blood pressure, cholesterol, diabetes, and heart function checked.
