Rates of angiography are considered too high among patients with suspected coronary heart disease (CHD), and limited empirical data address strategies to reduce angiography rates. In a randomized trial that enrolled 1202 patients from 6 hospitals in the United Kingdom, Greenwood and colleagues found that a cardiovascular magnetic resonance imaging (CMR)–guided care strategy produced a lower probability of protocol-defined unnecessary angiography in the subsequent 12 months than care guided by the UK National Institute for Health and Care Excellence guidelines. Unnecessary coronary angiography rates did not differ between CMR-guided and myocardial perfusion scintigraphy–guided care.
