| 目的 观察冠状动脉心肌桥(MB)对其近端冠状动脉周围脂肪组织(PCAT)参数的影响。方法 回顾性收集287例经冠状动脉CT血管造影(CCTA)检查未见冠状动脉斑块的临床疑诊冠状动脉心脏病患者;根据左前降支(LAD)有无MB将其分为MB组(n=150)与无MB组(n=137)。测量MB组LAD-MB长度及深度,并根据MB深度划分纵深型与浅表型亚组。比较组间及MB组内亚组间LAD PCAT参数——脂肪衰减指数(FAI)及脂肪总体积(FV);以单因素及多因素线性回归分析MB组临床因素(年龄、性别、体质量指数)及MB长度、深度与PCAT参数的相关性。结果 MB组FAI高于而FV低于无MB组(P均＜0.001)。MB组150例中,浅表型亚组99例、纵深型亚组51例;前者FAI低于而FV高于纵深型后者(P均＜0.001)。150例LAD-MB中位长度20.10 mm、中位深度0.80 mm。单因素线性回归分析显示,全部287例中,性别与FAI呈负相关; MB组 FAI与LAD-MB长度及深度均呈正相关,而FV与之均呈负相关(P均＜0.05)。多因素线性回归分析显示,MB组FAI与LAD-MB长度及深度均呈正相关(B=0.105、1.797,P均＜0.05)而 FV与后二者均呈负相关(B=－15.585、－162.343,P均＜0.05),FAI及FV均与临床因素无明显相关(P均＞0.05)。结论 MB可致其近端PCAT FAI升高、FV降低。 |

| 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. |
