Why Heart Attacks Kill Women

It is now not unusual for a woman (of any age), with no family history of heart disease, to suffer a heart attack and not even know it.

We have been inundated, and rightly so, with messages of what the symptoms are of an impending heart attack.  These are often for the heart attacks that men suffer, but women’s symptoms, and their response to these symptoms, may be far different.

The clutching chest pain and discomfort that we see in the movies may not be the signs for either gender.  Many people, especially women, even when they ‘allow’ themselves to acknowledge the symptoms,  end up in the hospital without ever having felt that telltale symptom (chest pain).  Telltale symptoms are different for men and women.  Women who have heart attacks are more likely than men to present with "atypical" symptoms.  Women also have much busier lives, often involving other family members, than ever before and even busier than many men so they don’t take the time to listen to their body’s complaints.

They have higher rates of mortality in the hospital as well.  This can be a combination of reasons:
  1. they get to the hospital too late (on average, an hour later than men) because:
  • they don’t recognize that they are having a heart attack, because of their symptoms;
  • they don’t think they should take the time from their daily ‘duties’ to others;
  • they don’t want to inconvenient others and so, they try to ignore the symptoms;
  • they have other symptoms from their body, at various times in their lives, that tend to mask , or divert attention from, the real cause this time;
      2.  at the hospital:
  • they don’t present with the expected symptoms (this was also most pronounced in younger heart attack patients);
  • they often experience a delay in diagnosis because they have different symptoms than men and so, their heart attack isn't recognized as such.

Chest pains and/or discomfort are still the expected symptoms but 35% of all patients don’t have them (42% of women; 31% of men). Why hasn’t this new scientific evidence overridden the historical anecdotal evidence ?

Both genders must pay attention to other signs of a heart attack such as pain or discomfort in one or both arms, as well as the back, neck or jaw. Shortness of breath and nausea or vomiting are other possible symptoms.(2)
