Magnetocardiography (MCG) is a promising noninvasive and accurate method for detecting myocardial ischemia. Although progress has been made in this area, there is a lack of studies using up-to-date examination instruments for the calibration of MCG analysis. This is a prospective single-center study aiming to build accurate analytical models of MCG to detect coronary lesions and myocardial necrosis. Coronary lesions are measured by coronary angiography (CAG) or coronary CTA, and are defined by both the stenosis degree and the computer-simulated fraction flow reserve. Myocardial necrosis is examined and quantified by cardiac MR. Healthy volunteers, chest pain patients who will receive CAG or CTA examination, and patients with acute myocardial infarction will be enrolled in this study.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Accuracy of MCG to detect coronary lesion
To establish an algorithm model of MCG in detecting coronary lesion and to assess the sensitivity and specificity of the above model in detecting coronary lesion. Coronary lesion is measured by degree of stenosis via CAG/CTA and computer-simulated fraction flow reserve via QFR/CTFFR.
Time frame: 24 hours
Accuracy of MCG to detect myocardial necrosis
To establish an algorithm model of MCG in detecting myocardial necrosis and to assess the sensitivity and specificity of this model in detecting myocardial necrosis, which is measured via cardiac MR.
Time frame: 24 hours
Accuracy of MCG to detect the localization of coronary lesion
To build up an algorithm model of MCG in detecting the localization of coronary lesion. Assess the sensitivity and specificity of this model to detect the main vessels where the lesion locates.
Time frame: 24 hours
Accuracy of MCG to detect the zone of myocardial necrosis
To establish an algorithm model of MCG to detect the infarct zone of the heart. Assess the sensitivity and specificity of this model to detect the location of myocardial necrosis.
Time frame: 24 hours
Started May 2022 (actual). Primary completion is estimated for Aug 2024, 27 months after the start.
Of 84 non-industry interventional studies with no phase under Chest Pain, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 43. This study's planned 27 months is above that.
Counting every sponsor, half of 86 studies reached it within 23 months; a quarter within 9 and three quarters within 43.
