Heart attacks in men versus women

Men may experience different signs of a heart attack from women. Why does it matter? Women are less likely to seek immediate medical care and are more likely to die from a heart attack.

  • Men normally feel pain and numbness in the left arm or side of chest. In women, these symptoms may appear on the right side. 
  • Women may feel completely exhausted, drained, dizzy or nauseous. 
  • Women may feel upper back pain that travels up into the jaw. 
  • Women may think stomach pain is the flu, heartburn or an ulcer.
