Stress cardiac magnetic resonance

Area of Science:

• Cardiology
• Medical Imaging
• Diagnostic Medicine

Background:

• Coronary artery disease (CAD) poses a significant health burden.
• Noninvasive imaging modalities like stress echocardiography, nuclear studies, and CT angiography are used for CAD evaluation.
• Stress cardiovascular magnetic resonance (CMR) has emerged as a recent advancement in patient assessment.

Purpose of the Study:

• To review the current applications of stress CMR for detecting significant CAD.
• To evaluate the role of stress CMR in prognostication of future cardiac events.
• To assess the diagnostic accuracy of stress CMR compared to other noninvasive techniques.

Main Methods:

• Review of clinical data on stress CMR for CAD detection and risk stratification.
• Comparison of stress CMR diagnostic capabilities with other established imaging modalities.
• Analysis of patient outcomes following normal adenosine stress CMR scans.

Main Results:

• Stress CMR demonstrates high accuracy in detecting significant CAD across diverse patient populations, comparable or superior to other methods.
• CMR offers unique advantages, including whole-heart visualization without imaging limitations and concurrent assessment of cardiac structures and function.
• Patients with a normal adenosine stress CMR scan exhibit an excellent prognosis with no adverse cardiovascular outcomes.

Conclusions:

• Stress CMR is an accurate and effective tool for diagnosing coronary artery disease.
• Normal stress CMR scans are associated with a favorable long-term prognosis.
• Stress CMR perfusion testing is appropriate for evaluating chest pain syndromes and indeterminate coronary lesions.
