Heart attacks are the leading cause of death in the U.S., fueled by stress and unhealthy lifestyles. While living healthily and reducing stress help, recognizing early warning signs could be lifesaving.

Here are key symptoms that may appear up to a month before a heart attack:

1. Swollen Feet – Caused by poor blood circulation, leading to fluid buildup.
2. Fatigue – Narrowed arteries mean less blood and oxygen, making you feel exhausted.
3. Shortness of Breath – A struggling heart can’t supply enough oxygen to the lungs.
4. Weakness – Muscles may feel weak due to reduced blood flow.
5. Dizziness and Cold Sweats – Poor brain circulation causes lightheadedness and clamminess.
6. Chest Pressure – Discomfort or pressure in the chest can build over time.
7. Flu-like Symptoms – Some feel cold or flu symptoms days before an attack.

If you notice any of these, seek medical help immediately. Early detection can save lives.
