Did you know heart attacks are the leading cause of death in the U.S.? A major reason is the

fast-paced, high-stress lifestyle many people live today, along with poor diets and junk food consumption.

While healthier habits and stress management help, recognizing early warning signs could

be life-saving—sometimes symptoms appear up to a month in advance.

One early red flag is swelling in your feet or ankles, which may signal poor circulation and fluid buildup (edema).

Persistent fatigue is another sign, often due to narrowed arteries reducing oxygen supply to your heart.

Shortness of breath, caused by reduced oxygen exchange between the heart and lungs, should also raise concern.

Other warning signs include muscle weakness, dizziness, and cold sweats, all potentially caused by limited blood

flow to the brain or muscles. Of course, chest discomfort—pressure, tightness, or pain—is one of the most recognizable

signs of an impending heart attack. Some people also report flu-like symptoms days before the event.

If you or someone you know experiences any of these symptoms, seek medical help immediately.

As Dr. Travis Stork and other experts emphasize: early awareness and quick action can save lives.
