| Research Abstract |
In this study, we performed magnetocardiographic study for early detection of the patients with coronary artery disease. Results: There were no electric current or only a weak current of leftward, inferior direction during ST interval in healthy subjects. However, in the patients with coronary stenosis exhibited 'abnormal current' during ST interval at rest, and this 'abnormal current' increased its magnitude after exercise. The directions of this 'abnormal current' coincided with the directions of the theoretical 'injury current'. We also succeeded to detect this abnormal current three-dimensionally. Moreover, we demonstrated this abnormal current will disappear about 10 days after coronary revascularization. We concluded magnetocardiography can detect the patients with coronary stenosis very sensitively.
