Authors' conclusion

PCI was effective across all ages in reducing angina frequency. Notably, there was limited improvement in treadmill exercise time in the elderly, challenging its role as a primary endpoint in many antianginal trials.

Study context

Population
Patients with stable angina and single- or multivessel CAD without background antianginal medication (ORBITA-2)all ORBITA-2 patients
Comparison
PCI vs placebo, by age
Primary endpoint
Interaction between age and PCI efficacy on ORBITA-2 primary and secondary endpoints

Primary result

As reported in the abstract

PCI vs PlaceboOdds ratio (95% CrI)
symptom relief, older patients; Pr > 0.99
2.03(1.67–2.45)
symptom relief, younger patients; Pr > 0.99
1.70(1.38–2.15)

Difference, s

treadmill exercise time, 50-year-old; Pr > 0.99
+125 (95% CrI 35.8–215.0)
treadmill exercise time, 70-year-old; Pr = 0.92
+31.9 (95% CrI −12.6 to 78.3)
