Hypothesis
Can adenosine stress perfusion cardiac magnetic resonance accurately identify the culprit vessel in patients with suspected ischaemic heart disease?
Conclusion
Adenosine stress perfusion CMR reliably identifies the territory supplied by the culprit vessel in most cases.
Supporting Evidence
- Of the 37 patients, 31 had significant epicardial stenosis.
- CMR accurately established the territory of the culprit vessel in 29 out of 31 patients.
- The specificity of stress perfusion CMR was reaffirmed at 84%.
Takeaway
This study shows that a special heart test can help doctors find out which blood vessel is causing heart problems.
Methodology
Retrospective study of patients with positive stress perfusion CMR and subsequent coronary angiography.
Limitations
The study is limited by its retrospective design and the small sample size.
Participant Demographics
60% male, mean age 65.1 years ± 11.3.
