Patients with acute chest pain often undergo noninvasive testing once myocardial infarction (MI) has been ruled out. In this randomized comparison of outpatient computed tomographic coronary angiography (CTCA)–guided care and usual care, researchers enrolled over 3000 patients (median age, 61 years; 70% male) with suspected acute coronary syndrome in whom MI had been ruled out and whose high-sensitivity cardiac troponin levels indicated intermediate risk for future cardiovascular events.
By 90 days, 92% of the CTCA group had undergone CTCA, compared with 2% of the usual-care group.
In the CTCA group, 32% had normal coronary arteries, 43% had nonobstructive coronary artery disease (CAD), and 23% had obstructive CAD.
