This is the first study that demonstrates the feasibility of in-scanner multi-parametric exercise stress cardiovascular magnetic resonance imaging in diagnosing significant coronary artery disease. The accuracy of the test was validated against gold-standard invasive fractional flow reserve.
Exercise stress tests are more physiological in replicating the symptoms and haemodynamic changes compared to pharmacological-induced stress, with less adverse events and better tolerated. However, due to limited availability of CMR-conditional stress equipment that precludes physiological-induced stress, conventional stress CMR typically refers to pharmacological-induced stress perfusion CMR. Treadmill exercise CMR has recently been shown to be accurate and cost-effective in diagnosing CAD. In this article, we examined the feasibility and accuracy of exercise CMR using in-scanner supine ergometer, which could minimise delay in imaging at peak stress and is able to acquire images at various exercise intensities. The proposed multiparametric supine exercise CMR could potentially shift the paradigm of CAD assessment.
To close the gap outlined above, learners will need to understand the availability and feasibility of exercise stress CMR using in-scanner supine ergometer to diagnose coronary artery disease, besides the conventional perfusion stress CMR.
