Visceral fat, including epicardial fat (EF) is recognized as a responsible factor of cardiovascular disease. The aim of this study was to investigate the relationship between EF and diabetes in Korean men.
EF thickness was measured in the left main coronary artery fat tissue (LMCA-fat) by low-dose chest CT scans in 1,048 Korean men (age above 20 years). LMCA-fat values were divided into quartiles and the prevalence of diabetes was analyzed based on the quartiles of LMCA-fat values using logistic regression.
There were significant correlations between LMCA-fat and body mass index (r = 0.169, p = 0.004), waist circumference (r = 0.172, p < 0.001), fasting glucose (r = 0.106, p = 0.037) and HbA1c (r = 0.176, p < 0.001). The patients in the higher LMCA-fat quartiles were associated with higher prevalence of diabetes (p for trend <0.001). Even after adjustment for multiple covariates, this association still remained statistically significant (p for trend = 0.022). The highest LMCA-fat quartile group was significantly associated with diabetes compared to the lowest quartile group. (OR = 3.26, 95% CI = 1.17-9.12).
These findings indicate that increased EF thickness is independently associated with the prevalence of diabetes in Korean men.
包括心外膜脂肪(EF)在内的内脏脂肪被认为是心血管疾病的一个致病因素。本研究的目的是调查韩国男性中EF与糖尿病之间的关系。
通过低剂量胸部CT扫描测量了1048名韩国男性(年龄在20岁以上)左主干冠状动脉脂肪组织(LMCA-脂肪)中的EF厚度。将LMCA-脂肪值分为四分位数,并使用逻辑回归分析基于LMCA-脂肪值四分位数的糖尿病患病率。
LMCA-脂肪与体重指数(r = 0.169,p = 0.004)、腰围(r = 0.172,p < 0.001)、空腹血糖(r = 0.106,p = 0.037)和糖化血红蛋白(r = 0.176,p < 0.001)之间存在显著相关性。LMCA-脂肪四分位数较高的患者糖尿病患病率较高(趋势p < 0.001)。即使在对多个协变量进行调整后,这种关联仍然具有统计学意义(趋势p = 0.022)。与最低四分位数组相比,最高LMCA-脂肪四分位数组与糖尿病显著相关(OR = 3.26,95%CI = 1.17 - 9.12)。
这些发现表明,EF厚度增加与韩国男性糖尿病患病率独立相关。
