WebThe prevalence of obstructive CAD defined by combined ICA-SPECT/MPI and ICA alone was 38 and 59%, respectively. The patient-based diagnostic accuracy defined by the area under the receiver operating characteristic curve (AUC) of integrated CTA-CTP for detecting or excluding flow-limiting CAD was 0.87 [95% confidence interval (CI): 0.84-0.91]. WebIn patients with flow-limiting CAD, tracer uptake into the myocardium is impaired and subsequently visualized in a manner specific to the imaging technique. There has been considerable national growth in cardiac stress testing. Between 1993–1995 and 2008–2010, stress testing has grown by ~60% in a risk-adjusted analysis.
