Abstract:
Objective To investigate the impact of coronary myocardial bridge(MB)on parameters of proximal pericoronary adipose tissue(PCAT).Methods Totally 287 patients with clinically suspected coronary heart disease but no coronary plaque on CT angiography(CCTA)were retrospectively collected.According to the presence or not of MB in left anterior descending(LAD),the patients were divided into MB group(n=150)and non-MB group(n=137).The length and depth of LAD-MB in MB group were measured,and patients in MB group were divided into deep MB subgroup and superficial MB subgroup according to LAD-MB depth.LAD PCAT parameters,i.e.fat attenuation index(FAI)and fat volume(FV),were compared between groups and subgroups within MB subgroup.Univariate and multivariate linear regression were used to explore the correlations of clinical factors(age,sex,body mass index),MB length,MB depth and PCAT parameters in MB group.Results FAI in MB group was higher,while FV was lower than those in non-MB group(both P＜0.001).Among 150 cases of LAD-MB,superficial type were found in 99 cases(superficial subgroup),while deep type were found in 51 cases(deep subgroup).FAI in superficial subgroup was lower,while FV was higher than those in deep subgroup(both P＜0.001).The median length and median depth of LAD-MB in 150 cases was 20.10 mm and 0.80 mm,respectively.Univariate linear regression analysis showed that for all 287 patients,gender was negatively correlated with FAI,whereas LAD-MB length and LAD-MB depth were positively correlated with FAI but negatively correlated with FV in MB group(all P＜0.05).Multifactor linear regression analysis showed that in MB group,both LAD-MB length and depth were positively correlated with FAI(B=0.105,1.797,both P＜0.05)and negatively correlated with FV(B=-15.585,-162.343,both P＜0.05),while clinical factors were not significantly correlated with FAI and FV(all P＞0.05).Conclusion MB could increase FAI and decrease FV of proximal PCAT.
