Heart attacks are the leading cause of death in the U.S., often due to stress and unhealthy eating. Knowing the signs a month before can be life-saving. Here are key symptoms to watch for:

1. **Swollen Feet**: Poor blood circulation causes fluid buildup in your legs and feet.
2. **Fatigue**: Narrowed arteries force your heart to work harder, leading to constant tiredness.
3. **Shortness of Breath**: Reduced blood flow affects oxygen supply, making breathing difficult.
4. **Weakness**: Poor circulation weakens muscles and increases the risk of falls.
5. **Dizziness/Cold Sweats**: Restricted blood flow to the brain causes dizziness and clamminess.
6. **Chest Pressure**: Pain or pressure in the chest often precedes a heart attack.
7. **Flu-like Symptoms**: Sudden cold or flu symptoms may signal an impending heart attack.

If you notice these signs, seek medical help immediately. Early detection is crucial.
