Here are foot-related signs that may appear a month before a heart attack:

1. Cold Feet or Toes

Consistently cold feet, even in warm environments, may signal poor blood flow.

A weakened heart may not pump blood efficiently to the extremities.

2. Swelling (Edema) in Feet and Ankles

Puffy, swollen feet and ankles could be due to fluid retention caused by heart failure.

Often worse at the end of the day or after sitting for long periods.
