Myocardial ischemia assessment by magnetocardiography in coronary artery disease patients after coronary artery bypass grafting
摘要
Abstract
Objective: To study the changes of magnetocardiography (MCG) in patients with coronary artery disease (CAD) after coronary artery bypass grafting. Methods: MCG mapping was performed in 34 CAD patients shortly there-after and 24 months after coronary artery bypass grafting by MCG-7 (MaGIC, Magscan GmbH) installed in an unshielded environment. Several parameters of MCG including ACTM (average classification of total maps), RAM (ratio of abnormal maps), R-max/T-max (ratio of the maximum magnetic value between R and T wave) were measured for detail analysis. Results:For patients just after bypass surgery , the MCG parameters ACTM, RAM (%) and R-max/T-max ratio were 3.41± 0.58, 73.94 ±28.15 and 6.60 ±2.42, respectively. After 24 months of follow-up , the parameters of MCG improved signifi-cantly (P<0.01); ACTM, RAM (%) and R-max/T-max ratio were 2.42 ±0.32, 54.79 ±22.83 and 5.65 ±2.12, respectively. Conclusions: As a new and noninvasive modality for detection of myocardial ischemia, MCG is a useful tool for long-term follow-up of coronary artery bypass grafting.关键词
