Core Concepts
Routine stress testing post-percutaneous coronary intervention (PCI) does not provide additional clinical benefits for high-risk patients.
Stats
The primary outcome was a composite of death, myocardial infarction, or hospitalization for unstable angina at 2 years.
At 2 years, there was no difference in the composite outcome between the functional testing and standard care group (6.2% vs 5.7%; HR, 1.09; 95% CI, 0.68-1.74; P = .73).
At 1 year, coronary angiography and repeat revascularization were > 2 times higher in the functional testing group compared to the standard care group.
