  • 目的  探讨冠状动脉粥样硬化性心脏病(冠心病)患者血清阴离子间隙(AG)水平与冠状动脉狭窄严重程度及全因死亡率的关系。方法  共入选2004年4月至2010年10月在5家临床中心就诊的18 115例冠心病患者。计算所有患者血清AG水平,根据冠状动脉狭窄支数和SYNTAX评分判断冠状动脉狭窄严重程度,分析血清AG水平与患者冠状动脉狭窄严重程度及术后30 d全因死亡率的关系。结果  共有4 510例(24.9%)患者血清AG水平超过16 mmol/L。根据血清AG水平四分位数将患者分为Q1组(AG<11.40 mmol/L,4 537例)、Q2组(11.40 mmol/L≤AG<13.52 mmol/L,4 558例)、Q3组(≥13.52 mmol/L≤AG<15.92 mmol/L,4 508例)和Q4组(≥15.92 mmol/L,4 512例)。单因素及多因素分析均显示,血清AG水平与冠状动脉狭窄严重程度无相关性(均P>0.05)。血清AG水平是术后30 d全因死亡率的独立预测因子,与Q1组比较,Q3、Q4组全因死亡风险明显增加(均P<0.05)。结论  高血清AG水平与冠心病患者的全因死亡风险增加显著相关,且独立于冠状动脉狭窄严重程度。

    【Abstract】Objective  To explore the relevance among serum anion gap(AG), severity of coronary stenosis and all-cause mortality in patients with coronary heart disease(CHD). Methods  Totally 18 115 patients with CHD were enrolled at 5 hospitals from April 2004 to October 2010. The serum level of AG was calculated in all patients; the severity of coronary stenosis was defined according to numbers of stenosis vessels and the SYNTAX score. Relations among serum AG, severity of coronary stenosis and postoperative 30 d all-cause mortality were analyzed. Results  There were 4 510 patients(24.9%) had serum AG>16 mmol/L. The patients were divided into Q1 group(AG<11.40 mmol/L, n=4 537), Q2 group(11.40 mmol/L≤AG<13.52 mmol/L, n=4 558), Q3 group(13.52 mmol/L≤AG<15.92 mmol/L, n=4 508) and Q4 group(AG≥15.92 mmol/L, n=4 512) according to the quartile values of AG. No correlation was observed between serum AG and severity of coronary stenosis(P>0.05). Serum AG was an independent predictor of postoperative 30 d all-cause mortality; the all-cause mortality risk in Q3 and Q4 group significantly increased compared to that in Q1 group(P<0.05). Conclusion  Elevated level of serum AG is associated with the risk of all-cause mortality but not the severity of coronary stenosis in patients with CHD.
