Stress CMR Perfusion Imaging in the United States (SPINS) Study

Randomized multicenter studies have demonstrated the high accuracy of vasodilator stress cardiac magnetic resonance imaging (CMR) in detecting coronary stenoses and in estimating impaired flow reserve in coronary artery disease (CAD). Stress CMR has also been shown in many studies to be an effective cardiac prognosticating method for patients presenting with chest pain syndromes. The American College of Cardiology Foundation and American Heart Association have recommended stress CMR as an appropriate test for evaluation of symptomatic patients with intermediate to high pre-test probability for CAD. However, stress CMR remains an underutilized method in the United States. SPINS (Stress CMR Perfusion Imaging in the United States: A Society for Cardiovascular Resonance Registry Study) is a multicenter observational study of patients with stable chest pain syndromes designed to evaluate the long-term performance of stress CMR for cardiovascular prognosis and to investigate the cost of additional downstream cardiac testing following the index stress CMR.
