The joint contribution of sex, age and type of myocardial infarction on hospital mortality following acute myocardial infarction.

ABSTRACT:

Objective

Younger, but not older, women have a higher mortality than men of similar age after a myocardial infarction (MI). We sought to determine whether this relationship is true for both ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI).

Design

Retrospective cohort study.

Setting

1057 USA hospitals participant in the National Registry of Myocardial Infarction between 2000 and 2006.

Patients

126 172 STEMI and 235 257 NSTEMI patients.

Main outcome measure

Hospital death.

Results

For both STEMI and NSTEMI, the younger the patient's age, the greater the excess mortality risk for women compared with men, while older women fared similarly (STEMI) or better (NSTEMI) than men (p<0.0001 for the age-sex interaction). In STEMI, the unadjusted women
