Input: Question: Do gender differences in health-related quality of life following ST-elevation myocardial infarction : women and men benefit from primary percutaneous coronary intervention to the same degree?
Answer: Compared to fibrinolysis treatment in patients with ST-elevation myocardial infarction, women do not seem to benefit from primary PCI to the same degree as men. Since previous studies have found no gender differences in clinical outcomes, this result may be specific to HRQoL.

no
