Although some studies have shown the potential utility of coronary magnetic resonance angiography (CMRA) for the detection of coronary artery disease (CAD), almost no information exists regarding its prognostic value. Aim of our study was to compare the predictive value of CMRA and coronary multislice computed tomography angiography (CCTA) for prediction of cardiovascular events at long-term follow-up, with invasive coronary angiography (ICA) as the reference method.
110 patients referred to MR for suspected or known CAD were prospectively included. A CMRA at 3T, a 64-slice CCTA and an ICA were performed in all patients. A luminal reduction ≥50% was defined as a significant stenosis. All patients were followed up for the occurrence of cardiovascular events, which comprised cardiovascular death, non-fatal myocardial infarction, necessity of revascularization and hospitalization due to cardiac events.
When assessing long-term prognosis, CMRA and CCTA demonstrated a similar prognostic value compared to invasive coronary angiography for prediction of cardiac events. CMRA has a non-inferior prognostic value compared to CCTA.
