4. Flu or Cold-Like Symptoms
Many people who have had heart attacks report experiencing flu-like symptoms days before the attack.
5. Chest Pressure
A typical heart attack symptom is chest tightness. This pressure may continuously increase until the heart attack occurs.
6. Swollen Feet
Congestive heart failure can cause one or both of the bottom chambers of the heart to lose their capacity for efficient blood pumping. Blood may back up in the legs, ankles, and feet, causing edema.
