摘要 目的评估胰岛素抵抗(IR)对非糖尿病急性冠状动脉综合征患者预后的影响。方法本研究为前瞻陛研究,人选332例非糖尿病急性冠状动脉综合征患者,使用稳态模式评估公式计算IR指数(HOMA.IR)。将研究对象分为高(HOMA—IR〈2,44例)、中(2≤HOMA2-IR〈6,99例)、低HOMA.IR组(HOMA2-IR≥6,179例),收集患者临床资料,并于出院1年后进行随访。采用方差分析、卡方检验比较3组的临床特点和预后情况,用多自变量logistic回归分析方法分析主要终点事件的影响因素。结果与中、低HOMA.IR组比较,高HOMA.IR组合并高血压(P=0.013)及血脂异常比例较高(P〈0.001),静息心率较快(P〈0.001),冠状动脉三支病变较多(P=0.017)。随访期间,高、中、低HOMA—IR组患者主要终点事件分别为64.3%(26/44)、54.7%(52/99)和41.3%(74/199),3组比较差异有统计学意义(P=0.034)。多因素logistic回归分析显示,高敏C反应蛋白(OR=1.012,95%CI:1.002~1.022,P=0.022)、HOMA—IR(OR=1.250,95%CI:1.043—1.497,P=0.015)、冠状动脉三支病变(OR=5.914,95%CI:2.947~11.868,P〈0.001)、心电图心肌缺血改变(OR=5.495,95%CI:2.925—10.324,P〈0.001)、LVEF≤40%(OR=13.205,95%CI:5.000~34.661,P〈0.001)是非糖尿病急性冠状动脉综合征患者随访期间的主要终点事件的独立危险因素。结论IR是影响非糖尿病急性冠状动脉综合征患者预后的重要因素。随着HOMA-IR的增加,非糖尿病急性冠状动脉综合征患者心脑血管事件显著增加。 Objective To evaluate the impact of insulin resistance (IR) on prognosis in non- diabetic acute coronary syndrome patients. Methods In this prospective study, we enrolled 332 non- diabetic patients suffering from acute coronary syndrome. The patients were divided into three groups by HOMA-IR which calculated by formula: low HOMA-IR group ( HOMA-IR 〈 2 ), 44 cases; moderate HOMA-IR group (2≤HOMA2-IR 〈6), 99 cases; high HOMA-IR group (HOMA≥6) with HOMA index, 179 cases. The in-hospital medical records of patients were compared, and all patients were followed up for one year after discharge. Results Incidence of hypertension ( P = 0. 013 ) , dyslipidemia ( P 〈 0. 001 ) , faster resting heart rate (P 〈 0. 001 ) and number of triple vessel coronary artery disease (P = 0. 017 )in high HOMA-IR group were significantly higher than in low and moderate HOMA-IR group. During follow-up, the major end-point events increased in proportion to IR grade: 64. 3 % (26/44) in the high HOMA-IR group, 54. 7% (52/99)in moderate HOMA-IR group and 41.3% (74/199)in low HOMA-IR group (P = 0. 034 ). Muhivariable logistic regression analysis showed that high sensitivity C reactive protein (OR = 1. 012,95% CI:1.002-1.022, P =0.022), HOMA-IR(OR = 1.250,95% CI: 1.043 - 1.497, P =0.015), triple vessel coronary artery disease ( OR = 5. 914,95% CI: 2. 947 - 11. 868, P 〈 0. 001 ), ischemic changes on ECG( OR =5. 495,95% CI:2. 925 - 10. 324, P 〈0. 001 )and low left ventricular ejection fraction ( LVEF≠ 40% ) ( OR = 13. 205,95% CI:5.000 -34. 661, P 〈0. 001 )were independent risk factor for major end-point events during follow-up. Conclusions Increased insulin resistance is linked with poor prognosis of non- diabetic patients with acute coronary syndrome.
