7 Warning Signs That Should Never Be Ignored Before a Heart Attack

3. Shortness of Breath

Difficulty breathing during rest or mild activity may indicate that the heart is not pumping efficiently.
4. Pain in Other Areas
Discomfort can spread to the arms, back, neck, jaw, or shoulders. This pain may feel dull rather than sharp.
5. Dizziness or Lightheadedness

Feeling faint, dizzy, or suddenly unsteady may be related to changes in blood flow.
6. Digestive Discomfort

Nausea, indigestion, or stomach discomfort—especially when combined with other symptoms—should be taken seriously.
