Health status relationship to ischemia and coronary artery disease severity in the ISCHEMIA trial

Am Heart JPublished

  • secondary analysis
  • proportional odds models, adjusted for age, sex, and baseline health status and stratified by baseline angina

Authors' conclusion

Among participants with baseline angina in the ISCHEMIA trial, severe ischemia was independently associated with more frequent angina at baseline and at 1 year, but also with better 1-year overall health status compared with less ischemia. Anatomic CAD severity was not associated with angina severity.

Study context

Population

Participants

Comparison
