Abstract. In July of 2008, the National Heart, Lung, and Blood Institute convened experts in noninva�sive cardiovascular imaging, outcomes research, statistics, and clinical trials to develop recommenda�tions for future randomized controlled trials of the use of imaging in: 1) screening the asymptomatic patient for coronary artery disease; 2) assessment of patients with stable angina; 3) identification of acute coronary syndromes in the emergency room; and 4) assessment of heart failure patients with chronic coronary artery disease with reduced left ventricular ejection fraction. This study highlights several possible trial designs for each clinical situation.
