Hypothesis
The in-hospital mortality rate among female patients would be higher than that among male patients.
Conclusion
Female patients who underwent PCI for AMI with a history of CABG had higher risks of in-hospital mortality, MACCEs, bleeding, and longer length of stay, especially among older patients.
Supporting Evidence
- Female patients exhibited elevated risks of in-hospital mortality compared to male patients.
- Female patients had a higher prevalence of major adverse cardiac or cerebrovascular events (MACCEs).
- Female patients experienced longer hospital stays than male patients.
Takeaway
Women who have heart surgery tend to have more problems in the hospital than men, especially if they are older.
Methodology
The study used the National Inpatient Sample database to analyze hospitalizations for AMI with a history of CABG who underwent PCI from 2016 to 2019, employing 1:1 propensity score matching.
Potential Biases

Limitations
The study is based on administrative data, which may contain coding errors and lacks clinical details such as medication and imaging data.
Participant Demographics
