Evaluating follow-up strategies for asymptomatic patients after heart surgery

Official title: Assessment in a Randomized Controlled Trial 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.

This study is testing if regular check-ups without stress tests are just as safe and effective for heart surgery patients who don’t have symptoms, compared to those who do have stress tests.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are asymptomatic patients with a history of coronary revascularization who are stable on their current medical treatment.

Probably not a fit

Patients with recent acute coronary syndrome or those exhibiting symptoms suggestive of angina will not benefit from this study.

What this trial studies

This trial assesses whether clinical follow-up without systematic stress testing is as effective as regular stress testing for asymptomatic patients who have undergone coronary revascularization. It aims to determine if avoiding stress tests can prevent major cardiac events without compromising patient safety. The study will compare outcomes such as death, heart attacks, and strokes between the two follow-up strategies over a long-term period. By randomizing participants, the trial seeks to provide evidence on the best approach for monitoring these patients.

Why it matters

Potential benefit: If successful, this study could lead to more cost-effective and safer follow-up care for patients after coronary revascularization.

How similar studies have gone: While there is limited evidence from randomized trials on this specific approach, the study aims to fill a gap in knowledge regarding follow-up strategies for asymptomatic patients.

   * 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
