BACKGROUND: The American College of Cardiology/American Heart Association exercise testing guidelines suggest that routine functional testing may benefit patients at high risk of restenosis, such as those undergoing multi-lesion percutaneous coronary intervention (PCI).
OBJECTIVES: To compare the six-month post-PCI clinical and procedural outcomes in patients following single- and multi-lesion PCI, and to examine the use of routine functional testing (ie, in all patients) versus selective functional testing (ie, only in those with recurrent symptoms) following multi-lesion PCI.
METHODS: Six-month outcomes among 562 patients after single-lesion PCI and 229 patients after multi-lesion PCI were examined. All patients were enrolled in the Routine versus Selective Exercise Treadmill Testing after Angioplasty (ROSETTA) registry, a prospective, multicentre registry examining the use of functional testing after successful PCI.
RESULTS: For single- versus multi-lesion PCI patients, respectively, rates of death (1.8% versus 2.2%, P=0.7) and myocardial infarction (0.7% versus 2.6%, P=0.03) were low in both groups. Rates of unstable angina (12.0% versus 11.7%, P=0.9) and the composite clinical end point of death, myocardial infarction or unstable angina (13.5% versus 13.9%, P=0.9) were similar. Multi-lesion PCI patients had a higher number of repeat PCI procedures (6.6% versus 13.4%, P=0.02) but there was no difference in the rates of coronary artery bypass graft surgery (3.0% versus 2.6%, P=0.7). A routine functional testing strategy was used in 28.0% of single-lesion and 31.6% of multi-lesion patients. In a multivariate analysis of the multi-lesion patients, routine functional testing was not associated with a significant reduction in the composite clinical event rate (odds ratio 0.5, 95% CI 0.2 to 1.7, P=0.27).
CONCLUSIONS: During the six-month period following successful PCI, clinical event rates were similar among patients undergoing single- or multi-lesion PCI. Routine functional testing was not associated with a statistically significant benefit in patients after multi-lesion PCI. However, additional study is required to better define the role of routine functional testing in this subgroup of patients.
