| The number of non-culprit lesions | 196 (49.2) | 28 (51.9) | 168 (48.8) |
Values are mean ± standard deviation, median (interquartile range) or n (%). P values signify statistical significance and reflect the differences between the MI cohort and UA cohort. MI, myocardial infarction; UA, unstable angina; ACS, acute coronary syndrome; BMI, body mass index; FAI, fat attenuation index; HU, Hounsfield unit.
