One month before a heart attack, your body may show you these 7 warning signs.

Many people who have had a heart attack report having symptoms similar to the flu just a few days before the heart attack occurred.

6. Feeling of tightness in the chest.
One common sign of a heart attack is feeling pressure in the chest. This pressure will keep rising until the attack occurs.
