Brief Summary
Early-Synergy investigates a diagnostic imaging approach in asymptomatic individuals from the general population for early detection of silent myocardial ischemia and cardiac dysfunction. The diagnostic imaging approach consists of cardiac computed tomography for coronary artery calcium scoring (CT-CAC) and cardiac magnetic resonance (CMR) stress perfusion imaging. Early-Synergy investigates the effect of early detection of silent myocardial ischemia and cardiac dysfunction by CMR in asymptomatic individuals with increased CAC. In addition, the diagnostic yield of CMR for early detection of silent myocardial ischemia and cardiac dysfunction is investigated. Asymptomatic individuals at increased risk (CAC ≥ 300) are therefore randomized 1:1 to either CMR stress perfusion imaging or a control group.
