Abstract:
It was a cross-sectional study. Six myocardial infarction patients with non-obstructive coronary artery disease (MINOCA group) admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2021 to August 2022 were enrolled in the study and 78 healthy subjects were selected as control group. The patients and healthy controls were selected with 1∶1 propensity score matching according to age, gender, body mass index, occupation and marriage status; and 5 study subjects of each group were finally enrolled in the study. The general clinical data and magnetocardiographic (MCG) results were collected from the hospital′s electronic medical record system. Compared with control group, MINOCA group showed abnormal QR rotation, discrete changes in positive and negative magnetic poles in TT segment, and disordered current direction. The analysis of MCG data revealed 35 parameters with statistically significant difference between the two groups, involving TT interval, QRS complex, RS interval and QR interval. This study explored the magnetocardiographic characteristics of MINOCA, which suggest that MCG may be conducive for diagnosis of MINOCA in the future.
