Health Status Outcomes With Percutaneous Coronary Intervention and Coronary Artery Bypass Grafting in ISCHEMIA

CirculationPublished

  • Secondary analysis of the ISCHEMIA randomised trial
  • risk-adjusted proportional odds models

Authors' conclusion

In ISCHEMIA, both PCI and CABG were associated with better 3-year health status than conservative management. Better angina relief with CABG than PCI was seen at 1, but not 3, years.

Study context

Population
Patients with chronic coronary disease in ISCHEMIA
Participants
2,232 / 1,198 / 340
Comparison
Percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) vs conservative strategy
  • Conservativen = 2,232reference
  • PCIn = 1,198
  • CABGn = 340
Primary endpoint
SAQ-7 summary score (SAQ-SS) and angina frequency score (SAQ-AF); higher = better health status
Follow-up
1 and 3 years
