A recent study in JAMA has provided further evidence regarding some key issues in ACS/MI presentations which seem to be commonly taught but often forgotten in actual practice. Here's just a few of the key findings from this study:
1. Generally speaking, women were more likely to present without chest pain than men, and the difference between the sexes was most apparent in the < 45yo groups. Overall, 42% of women presented with painless MIs. [remember from a recent prior cardiology pearl that painless MIs have a higher mortality as well]
2. Women had a higher mortality than men within the same age groups, and the difference between the sexes was most apparent in younger ages.
3. Almost 1/5 of women < 45 yo with MI did not report chest pain. [We've always assumed it's just the older women that present with painless MIs....not true!]
A final point that should be re-stated: young women DO have MIs, they DO often present without pain, and they DO often die. Be wary.
