Assessment of Adverse Outcome in Asymptomatic Patients With Prior Coronary Revascularization Who Have a Systematic Stress Testing Strategy Or a Non-testing Strategy During Long-term Follow-up.

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.

Eligibility

Inclusion Criteria:

1. Prior coronary revascularization (PCI or CABG) at any time before randomization.
2. Asymptomatic at the time of randomization (defined as a Canadian Cardiovascular Society score ≤ 1, stable on the current medical treatment).
3. Patient affiliated to Social Security
4. Informed, written consent from the patient

Exclusion Criteria:

1. Age \< 18years
2. Any acute coronary syndrome in the previous 3 months
3. Symptoms suggestive of angina pectoris at the time of randomization:

   * Angina is characterized by ischemic chest pain occurring on exertion or stress relieved by rest and/or nitroglycerine.
   * Angina equivalents are defined as dyspnea, fatigue, or diaphoresis on exertion evaluated by the principal investigator as abnormal and attributable to myocardial ischemia.
4. Any severe valvular disease
5. Prior heart transplantation
6. Class III or IV symptomatic heart failure (NYHA classification).
7. Persons whose occupations impact on public safety (e.g. airline pilots, lorry or bus drivers) in whom systematic stress testing could be required for medico-legal reasons
8. Malignancies and other comorbid conditions with a life expectancy \< 2 years
9. Pregnancy or nursing women
10. Women of childbearing age without effective birth control or intention to become pregnant during the course of the trial
11. Simultaneous enrollment in an interventional clinical trial and interventional research with minimal risks and burden
12. Inability to sign an informed consent. Patient under legal protection (guardianship, curatorship) or mental condition (psychiatric or organ cerebral disease) rendering the subject unable to understand the nature, scope, and possible consequences of the trial or mental retardation or language barrier such that the patient is unable to give informed consent
