A bluish or violet hue may indicate low oxygen supply.

Pale or ashy feet may indicate reduced blood circulation.

4. Numbness or tingling

Reduced blood flow can lead to tingling or numbness.

This can 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 sores that don’t heal

Poor blood circulation can prevent the body from healing even small cuts.

Chronic ulcers or slow-healing wounds on the feet are a warning sign, especially in diabetics.

6. Pain when walking (halting)

Pain or cramps in the feet or calves when walking may indicate peripheral arterial disease (PAD).

It is a reliable indicator of future cardiovascular events, including heart attacks.

❗ Important note:

These signs don’t always mean that a heart attack is imminent, but they do indicate that your cardiovascular system may be affected.

 

✅ What to do if you notice these symptoms:

Contact a doctor immediately, especially if symptoms are new or worsen.

– Be aware of 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.
