  • global, multicenter
  • stratified by treatment strategy
  • Cox proportional hazards models adjusting for 17 clinical covariates

Authors' conclusion

In patients with chronic coronary disease, the most recent SAQ-SS is the strongest health status predictor of future cardiovascular events. Serial SAQ-SS assessments provide a practical, dynamic, and patient-centered approach for updating prognosis in chronic coronary disease management.

Study context

Population
Patients with chronic coronary disease in the ISCHEMIA trial with serial Seattle Angina Questionnaire Summary Score (SAQ-SS) assessments (3-month score as prior, 6-month score as current)participants included in this analysis · conservative management 1,965 · invasive management 1,440
Participants
3,405 patients
Comparison
Association of the prior score, the current score, and the change in scores with ISCHEMIA's primary composite end point, stratified by treatment strategy
  • conservative managementn = 1,965
  • invasive managementn = 1,440
Primary endpoint
ISCHEMIA's primary composite end point:
  • Cardiovascular death
  • Myocardial infarction
  • Hospitalization for unstable angina
  • Heart failure
  • Resuscitated cardiac arrest
Follow-up
Median 3.2 years

Primary result

As reported in the abstract

Hazard ratio (95% CI)
each 5-point increase in the current SAQ-SS (conservative cohort)7% lower risk of the primary end point
0.93(0.90–0.96)
each 5-point increase in the current SAQ-SS (invasive cohort)9% lower risk
0.91(0.86–0.96)
