摘要 目的 分析稳定型心绞痛合并高尿酸血症患者血栓弹力图的结果.方法 选取2011年1月至2013年12月于首都医科大学附属北京安贞医院经皮冠状动脉介入术(PCI)并置入支架的稳定型心绞痛患者450例,按照是否合并高尿酸血症分为高尿酸血症组(129例)和正常尿酸组(321例),入院后行常规检查及血栓弹力图检测.比较2组一般资料以及血栓弹力图各指标的差异.结果 高尿酸血症组年龄、体质量、男性比例、吸烟、三酰甘油、低密度脂蛋白胆固醇和高敏C反应蛋白明显高于正常尿酸组[(57±15)岁比(52±16)岁、(82±19) kg比(74±21) kg、80.6%(104/129)比62.6%(201/321)、69.0%(89/129)比44.6% (143/321)、(2.8±1.2) mmol/L比(2.0±1.3) mmol/L、(4.0±1.4) mmol/L比(2.8±1.2) mmol/L、(5.7±1.4)mg/L比(3.3±1.1) mg/L],差异均有统计学意义(均P<0.05).单因素及多因素回归分析均显示高尿酸血症与二磷酸腺苷抑制率呈正相关(r=0.952,0.893,P<0.01).高尿酸血症组患者的血栓弹力图主要参数,包括反应时间(R值)、R结束到振幅达20 mm所用的时间(K值)均低于正常尿酸组,血栓形成的最大幅度(MA值)和血凝块形成的速率(α角)均高于正常尿酸组,差异均有统计学意义[(4.9 ±0.9)min比(5.2±1.1)min、(1.4±0.4) min比(1.9±0.4)min、(58±11)mm比(52 ±9)mm、(67±10)°比(60±11)°,P<0.05].2组间花生四烯酸抑制率差异无统计学意义(P>0.05),高尿酸血症组二磷酸腺苷抑制率低于正常尿酸组,差异有统计学意义[(65±21)%比(70±25)%,P<0.01];高尿酸血症组氯吡格雷抵抗的发生率明显高于正常尿酸组[24.0%(31/129)比16.2% (52/321)],差异有统计学意义(P<0.05).结论 稳定型心绞痛合并高尿酸血症患者血液呈高凝状态,氯吡格雷抵抗发生率高,其PCI置入支架后需加强抗血小板治疗. Objective To analyze the thromboelastography (TEG) outcomes of patients with stable angina pectoris (SAP) complicated with hyperuricemia (HUA).Methods Four hundred and fifty patients with SAP who underwent percutaneous coronary intervention (PCI) from January 2011 to December 2013 were enrolled and randomly divided into SAP complicated with HUA group (HUA group,129 cases) and without HUA group (non HUA group,321 cases).All the patients received routine examination and TEG test,and the results were compared between the two groups.Results The patients in HUA group had a higher rate of male and smoker,elder age,higher level of body weight,triglyceride,low density lipoprotein-cholestero and high sensitive C-reactive protein compared with those in normal group[80.6% (104/129) vs 62.6% (201/321),69.0% (89/129) vs 44.6% (143/321),(57±15) vs (52±16) years,(82±19) kg vs (74±21) kg,(2.8±1.2) mmol/L vs (2.0±1.3) mmol/L,(4.0±1.4) mmol/L vs (2.8±1.2) mmol/L,(5.7±1.4) mg/L vs (3.3±1.1) mg/L] (P〈0.05).Both single-factor and multi-factor regression showed that HUA was significantly correlated with adenosine diphosphate (ADP) inhibition rate (r =0.952,0.893,both P 〈0.01).In TEG,statistical differences were found in R value (time of latency from start of test to initial fibrin formation),K value (time taken to achieve amplitude 20 mm),maximum amplitude value and α-angle (the rapidity of fibrin build-up and cross-linking) between HUA group and non HUA goup [(4.9±0.9) minvs (5.2±1.1) rain,(1.4±0.4) min vs (1.9±0.4) min,(58±11)mm vs (52 ± 9) mm,(67 ± 10) ° vs (60 ± 11) °,P 〈 0.05].ADP inhibition rate was significantly lower in HUA group compared with non-HUA group [(65 ± 21) % vs (70 ± 25) %,P 〈 0.01];no statistical difference of AA inhibition rate was found between the two groups (P 〉0.05).The incidence of clopidogrel resistance was higher in HUA group than that in non HUA group [24.0% (31/129) vs 16.2% (52/321),P 〈 0.05].Conclusion SAP patients complicated with HUA have more incidences of hypercoagulation states and clopidegrel resistance.
