Hypothesis
The study aims to evaluate the feasibility and diagnostic performance of rest/stress perfusion, late gadolinium enhancement, and MRCA in patients with suspected coronary artery disease compared to invasive angiography.
Conclusion
The combination of stress perfusion, late gadolinium enhancement, and MRCA is feasible, but adenosine stress perfusion alone outperforms CMR coronary angiography.
Supporting Evidence
- The sensitivity for adenosine stress perfusion was 87%, while late gadolinium enhancement had a sensitivity of 50%.
- The combination of tests did not significantly improve diagnostic performance compared to perfusion alone.
- In patients with excellent image quality, the combination of MRCA, PERF, and LGE yielded a sensitivity of 86%.
Takeaway
Doctors used special heart scans to see if patients had heart problems, and found that one type of scan worked best on its own.
Methodology
Fifty-four patients underwent CMR including MRCA, stress and rest perfusion, and late gadolinium enhancement, with results compared to invasive angiography.
Potential Biases
The study may not be generalizable to a broader population due to the selective inclusion of patients.
Limitations
The study had a relatively low patient number and included a highly selected population referred for invasive coronary angiography.
Participant Demographics
Patients had an intermediate pre-test probability for CAD (48%) with similar cardiovascular risk factors across groups.
