Comparative accuracy of myocardial perfusion imaging: The final answer has yet to come

In patients with suspected or known coronary artery disease (CAD) the presence of stress-induced myocardial ischemia is still considered an indication for invasive coronary angiography (ICA) and, if needed, coronary revascularization. This management is based on the “dogma” that in patients with CAD the presence and extent of inducible myocardial ischemia predicts adverse cardiovascular events, and that the reduction of ischemic burden would have a favourable impact on patients' outcome [1]. These considerations have been further reinforced by recent data d emonstrating the extremely low diagnostic yield of ICA, with only about one third of the patients showing CAD amenable for revascularization [2], stressing on the need for a better selection of patients with suspected ischemic heart disease (IHD).
