Hypothesis
Strain-Encoded-MRI (SENC) during high-dose dobutamine stress testing can provide better prognostic value than conventional wall motion analysis for patients with coronary artery disease.
Conclusion
Strain-Encoded-MRI helps identify patients at high risk for future cardiac events more accurately than traditional methods.
Supporting Evidence
- 35 hard events occurred during a 28±9 month follow-up period.
- Inducible strain defects were strongly associated with cardiac outcomes.
- A cut-off value of <1.64 for strain rate reserve was highly predictive for future hard cardiac events.
Takeaway
This study shows that a special type of MRI can better predict heart problems than regular methods, helping doctors find patients who need more care.
Methodology
320 patients underwent DS-MRI, assessing wall motion and SENC at baseline and during stress, with follow-up data collected on cardiac events.
Participant Demographics
Patients with suspected or known coronary artery disease.
