Brief Summary

Magnetocardiography (MCG) is a non-invasive and accurate method of detecting myocardial ischemia. However, the previous MCG is limited in clinical practice due to its high working conditions and limited sensitivity. The next-generation MCG based on optical pumped magnetometer (OPM) has the advantages of high sensitivity, high reliability, high usability and low cost, which makes it suitable for most medical scenarios. Thus, this prospective single-center study aimed to use OPM MCG to explore its diagnostic efficacy and predictive value for myocardial ischemia. Participants who will receive coronary angiography examinations will be enrolled in this study. Participants enrolled in the study will also have a 1, 3, 6, 12, 24, 36, and 48-month follow-up for analysis of adverse cardiac events.

Outcome Measures

Primary Outcomes (4)

  • Sensitivity of diagnosis of myocardial infarction level

    The myocardial ischemic level is measured by MCG and coronary angiography examination. The result of the coronary angiography examination is independently judged by three experienced clinicians. And calculate the sensitivity to evaluate the diagnosis of myocardial infarction level validity.

    up to 6 months

  • Specificity of diagnosis of myocardial infarction level

    The myocardial ischemic level is measured by MCG and coronary angiography examination. The result of the coronary angiography examination is independently judged by three experienced clinicians. And calculate the specificity to evaluate the diagnosis of myocardial infarction level validity.

    up to 6 months

  • Consistency of diagnosis of myocardial infarction level

    The myocardial ischemic level is measured by MCG and coronary angiography examination. The result of the coronary angiography examination is independently judged by three experienced clinicians. Calculate the consistency to evaluate the diagnosis of myocardial infarction level reliability.

    up to 6 months

  • Kappa statistics of diagnosis of myocardial infarction level

    The myocardial ischemic level is measured by MCG and coronary angiography examination. The result of the coronary angiography examination is independently judged by three experienced clinicians. Calculate the Kappa statistics to evaluate the diagnosis of myocardial infarction level reliability.

    up to 6 months
