A recent article in JAMA (2012;307(8):813-822) found that women are 30% less likely than men to have chest pain or discomfort during a heart attack, especially under the age of 45. Because of this, women are more likely to die in the hospital than men because the diagnosis takes longer to make.
Between the ages of 65 to 74, these symptoms were about the same and by age 75, the difference between men and women having chest pain associated with a heart attack is only 3%.
This study reviewed the records of more than 1 million men and women from 1994 to 2006 who were in the National Registry of Myocardial Infarction, The reasons for these differences in heart attack and pain for men and women is not yet known.
