Prospectively Gated Coronary CT Angiography in Bypass Grafts: Dramatic Reductions in Radiation Dose

perfusionCMRpositive for ischaemia, 266 (73%)werenegative. Of the 266 negative CMR, MACE was encountered in only six (2%) patients (five PCI and one death due to heart failure). Accordingly a negative stress CMRafforded a freedom fromMACE of 98%. Conclusion: In patients at intermediate risk for cardiovascular events, a negative stress perfusion CMR is associated with an excellent prognosis. doi:10.1016/j.hlc.2011.05.463
