Clinical Trial Summary

Due to the lack of randomized controlled trials, the best follow-up strategy of asymptomatic patients after coronary artery revascularization is controversial. A systematic screening of silent myocardial ischemia may help prevent a major acute cardiac event. However, systematic screening strategy is costly and there is currently no evidence that repeated revascularization improve survival. Moreover, stress testing per se or additional procedures which can be performed with regard of stress testing results can cause unexpected complications.

ARCACHON is a national, multicenter, randomized, open label trial, that will evaluate the non-inferiority of a clinical follow-up as compared to a systematic stress testing strategy after coronary revascularization.


Clinical Trial Description

Coronary artery revascularization is commonly used for the management strategy of patients with coronary artery disease (CAD).

In the following years after revascularization, the current guidelines recommend evaluation with stress tests when patients are symptomatic. Due to the lack of randomized trials, the evaluation of asymptomatic patients is controversial and accordingly there is a wide variation in routine follow-up strategies in these patients. A systematic screening of silent myocardial ischemia may help prevent a major acute cardiac event. However, systematic screening strategy is costly and there is currently no evidence that repeated revascularization improve survival We hypothesized that clinical follow-up alone would be non-inferior to systematic stress testing screening strategy during follow-up of asymptomatic CAD patients with prior coronary revascularization.

The primary objective of ARCACHON trial is to demonstrate the non-inferiority of a strategy of clinical follow-up (without non-invasive stress testing) in asymptomatic patients with a history of coronary revascularization compared to a strategy of systematic screening for myocardial ischemia using non-invasive stress testing by the primary endpoint as the composite of: all-cause death, myocardial infarction, stroke or any cardiovascular event leading to unplanned hospitalization. ;
