Hypothesis
What is the impact of previous repeated percutaneous coronary intervention (PCI) on subsequent coronary artery bypass grafting (CABG)?
Conclusion
Repeated PCI increases risk for long-term prognosis of subsequent CABG.
Supporting Evidence
- Patients with a history of repeated PCI had significantly lower survival rates after CABG.
- Freedom from all-cause death and cardiac death was significantly lower in patients with multiple previous PCI.
- Multivariate analysis identified previous PCI as an independent risk factor for cardiac death.
Takeaway
If someone has had many heart procedures called PCI before getting heart surgery, it might make their recovery harder and their chances of living longer lower.
Methodology
The study compared outcomes of 894 patients who underwent CABG, divided into groups based on their history of PCI.
Potential Biases
The worse outcomes may be attributed to higher coronary risks in patients with previous PCI.
Limitations
The study was nonrandomized and retrospective, and the sample size was limited.
Participant Demographics
The study included 894 patients with varying histories of PCI, with a mean age around 66 years.
