Objective:

To evaluate the utility of magnetocardiography (MCG) in diagnosing coronary microvascular dysfunction (CMD) in patients with suspected angina pectoris and non-obstructive coronary arteries.

Approach:
    Key Findings:
    • MCG identified ischemic features in patients with suspected ANOCA despite normal ECG results.
    • Distinct morphological differences in MCG waveforms were observed between patients with suspected ANOCA and healthy controls.
    • MCG may optimize the diagnostic workflow for patients with acute chest pain.
    Interpretation:

    The findings support MCG's potential in detecting subtle ischemia in patients with suspected ANOCA, which may enhance diagnostic accuracy and efficiency.

    Limitations:
    • The study involved a small sample size of only three patients.
    • Further research is needed to systematically characterize MCG waveform patterns in a larger cohort.
    Conclusion:

    MCG shows promise as a rapid, non-invasive diagnostic tool for evaluating patients with suspected ANOCA.
