Magnetocardiography in the Accurate Identification of Severe Coronary Lesions and Myocardial Necrosis
September 16, 2022 updated by: Qilu Hospital of Shandong University
Ultra-sensitive Magnetocardiography in the Accurate Identification of Severe Coronary Lesions and Myocardial Necrosis
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.

Exclusion Criteria:
- Patients with known structural heart disease such as cardiomyopathy and valvular disease;
- Patients with arrhythmias such as atrial fibrillation, supraventricular tachycardia, and atrioventricular block that have not returned to normal;
- History of other cardiovascular diseases such as pulmonary embolism and aortic dissection;
