目的:了解冠心病患者体脂分布与冠状动脉(冠脉)病变程度的关系。方法:69例冠心病患者,用MSCT评估心外膜脂肪体积(EFV)、腹部总脂肪体积(TFV)、内脏脂肪体积(VFV)、皮下脂肪体积(SFV),同时测量身高、体重,计算体质指数(BMI),测量腰围、臀围,计算其比值(WHR),分别通过Gensini积分系统和冠脉粥样斑块积分系统评估冠脉病变程度。分析体脂分布与冠脉病变程度的关系及EFV与各种体脂评价指标的关系。结果:体重、BMI、腰围、WHR、VFV、TFV、EFV与冠脉病变评分呈正相关(P<0.05),以VFV和EFV与冠脉病变相关性最强(r=0.356)。EFV与体重、BMI、腰围、臀围、WHR、VFV、TFV呈正相关相关(P<0.05),与VFV相关性最强(r=0.630),与SFV无明显相关。结论:在冠心病患者中,VFV及EFV是反映冠脉病变程度的较佳指标,VFV与EFV具有较好的相关性,可以通过心外膜脂肪的量评估内脏型肥胖。
Objective: To understand the relationship between body fat distribution and the severity of coronary artery (coronary artery) in patients with coronary heart disease. Methods: 69 patients with coronary heart disease were evaluated by MSCT for epicardial fat volume (EFV), total abdominal fat volume (TFV), visceral fat volume (VFV), and subcutaneous fat volume (SFV) Index (BMI), waist circumference and hip circumference were measured. The ratio of WHR was calculated. The extent of coronary lesion was evaluated by Gensini integral system and coronary atherosclerotic plaque score system respectively. The relationship between body fat distribution and the degree of coronary artery disease and the relationship between EFV and various body fat evaluation indexes were analyzed. Results: Body weight, BMI, waist circumference, WHR, VFV, TFV and EFV were positively correlated with coronary artery disease score (P <0.05). VFV and EFV had the highest correlation with coronary artery disease (r = 0.356). EFV was positively correlated with weight, BMI, waist circumference, hip circumference, WHR, VFV and TFV (P <0.05), and had the highest correlation with VFV (r = 0.630). Conclusion: In patients with coronary heart disease, VFV and EFV are the better indicators reflecting the severity of coronary artery disease. VFV has good correlation with EFV, and visceral fat can be evaluated by the amount of epicardial fat.
