摘 要:目的 探究肥胖和超重对冠状动脉粥样硬化性心脏病(冠心病)患者左心室结构和功能的影响。 方法 选取2014年9月至2015年3月首都医科大学附属北京安贞医院 经冠状动脉造影术确诊为冠心病(至少1支冠状动脉狭窄≥50%)的患者367例。根据体重指数将患者分为3组,体重指数〈24.0 kg/m2为正常组(77例), 24.0~27.9 kg/m2为超重 组(178例),≥28 kg/m2为肥胖组(112例)。常规询问病史,并进行身高、体质量、腰围及臀围测量,检测高敏C反应蛋白(hs-CRP)、白细胞介素6(IL-6)及肿瘤坏死因子α (TNF-α)水平,通过心脏超声测算左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、左心房内径、左心室射血分数(LVEF)、舒张早期二尖瓣血流速度峰值(E) 及舒张晚期二尖瓣血流速度峰值(E)。比较3组患者左心室结构和功能指标差异,分析体重指数与各指标的相关性。 结果 超重组E值大于正常组[(73±20)mm/s比(68±19 )mm/s],肥胖组LVEDD、E值大于正常组及超重组[(50±5)mm比(48±7)、(48±5)mm,(78±20)mm/s比(68±19)、(73±20)mm/s],差异均有统计学意义(均P〈0.05 )。超重组和肥胖组患者hs-CRP明显高于正常组,差异有统计学意义(P〈0.05)。体重指数值与LVEDD、LVESD、左心房内径、hs-CRP、IL-6及TNF-α呈正相关(均P〈0.05)。在包含 年龄、性别、高血压病史及糖尿病史的多元线性回归中,体重指数与LVEDD相关(β=0.127,P=0.022)。 结论 体重指数较高的冠心病患者左心室内径增大、舒张功能减低, 炎性反应可能是其中机制之一。Objective To investigate the effect of obesity and overweight on left ventricular structure and function in patients with coronary atherosclerotic heart disease(CHD). Methods Totally 367 patients diagnosed of CHD(at least 1 coronary artery stenosis≥50%) from September 2014 to March 2015 in Beijing Anzhen Hospital, Capital Medical University were enrolled. The patients were divided into 3 groups according to body mass index(BMI): normal weight group(BMI〈24.0 kg/m2, 77 cases), overweight group(BMI 24.0-27.9 kg/m2, 178 cases), obesity group(BMI≥28 kg/m2, 112 cases). Height, body mass, waistline and hipline were measured; high sensitive C-reactive protein(hs-CRP), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α) were tested; left venticular end-diastolic diameter(LVEDD), left venticular end-systolic diameter(LVESD), left atrial diameter(LAD), left venticular ejection fraction(LVEF), mitral peak early flow velocity(E) and peak late flow velocity(A) were determined. The correlation between BMI and left venticular indexes was analyzed. Results The E value in overweight group was significantly higher than that in normal weight group[(73±20)mm/s vs (68±19) mm/s](P〈0.05), LVEDD and E value in obesity group were significantly higher than those in normal weight group and overweight group[(50±5) mm vs (48±7),(48±5)mm;(78±20)mm/s vs (68±19),(73±20)mm/s](P〈0.05). The hs-CRP level in overweight group and obesity group were significantly higher than those in normal weight group (P〈0.05). BMI was positively correlated with LVEDD, LVESD, LAD, hs-CRP, IL-6 and TNF-α (all P〈0.05). Multivariate linear regression showed that BMI was correlated with LVEDD(β=0.127, P=0.022). Conclusion CHD patients with obesity are associated with large left venticular diameter and bad diastolic function; the mechanism may be related to inflammatory response.
