International Study of Comparative Health Effectiveness with Medical and Invasive Approaches
Sponsor: NIH: NHLBI
Purpose: The purpose of the ISCHEMIA trial is to determine the best management strategy for higher-risk patients with stable ischemic heart disease. This is a multicenter randomized controlled trial with a target enrollment of ~8000 patients with at least moderate ischemia on stress imaging. Patients will be assigned at random to a routine invasive strategy (INV) with cardiac catheterization (cath) followed by revascularization plus optimal medical therapy (OMT) or to a conservative strategy (CON) of OMT, with cath and revascularization reserved for those who fail OMT.
- At least moderate ischemia on a stress imaging test with nuclear myocardial perfusion (≥10% myocardium), echo or cardiac magnetic resonance wall motion (≥3/16 segments with stress-induced severe hypokinesis or akinesis), or cardiac magnetic resonance perfusion (≥12% myocardium).
- Participant is willing to comply with all aspects of the protocol, including adherence to medical therapy and follow-up visits
- Age > 21 years
