摘 要:目的 观察尼可地尔对急性ST段抬高型心肌梗死患者行急诊经皮冠状动脉介入治疗(PCI)后室性心律失常的影响.方法 前瞻性纳入2015年1月至2016年6月在聊城市第二人民医院住院的120例急性心肌梗死患者,所有患者采用数字表法分为对照组和尼可地尔组,每组60例,两组均给予常规治疗,术前尼可地尔组服用尼可地尔10 mg,对照组则服用安慰剂.术后尼可地尔组患者继续服用尼可地尔5 mg/次、3次/d,对照组继续服用安慰剂,比较两组患者术后3d的QT间期离散度(QTd)、校正的QT间期离散度(QTcd)以及室性心律失常发生率.结果 尼可地尔组术后6、24、48和72 h的QTd分别为(70.6±4.4)、(67.2±5.3)、(55.7±8.5)和(48.2±8.2) ms,均低于对照组的(77.1±7.1)、(71.3±6.5)、(65.1 ±8.1)和(57.2±5.4) ms(t=13.523、15.376、17.318、20.315,均P <0.05);尼可地尔组术后6、24、48和72 h的QTcd分别为(77.5±7.7)、(67.7±8.6)、(61.2±7.5)和(52.9±8.4) ms,均低于对照组的(88.6±8.1)、(79.2±7.8)、(74.4±7.4)和(69.6±8.6) ms(t=15.397、18.582、20.342、27.352,均P<0.05);术中再灌注性心律失常发生率差异无统计学意义,术后3d内尼可地尔组室性早搏发生率为41.7%(25/60),明显低于对照组的75.0%(45/60,x2=6.52,P<0.01);尼可地尔组非持续性室性心动过速及心室颤动发生率为10.0%(6/60),明显低于对照组的30.0%(18/60,x2=7.42,P<0.01).结论 尼可地尔可减少急性心肌梗死患者PCI术后室性心律失常的发生,其机制可能与QTd及QTcd较低有关.Objective To investigate the effect of nicorandil on ventricular arrhythmia in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with emergent percutaneous coronary intervention (PCI).Methods A total of 120 acute STEMI patients treated with emergent PCI in our hospital from January 2015 to June 2016 were randomly divided into control group and experiment group (n =60 each).Patients in both groups received conventional therapy.Patients in experiment group took 10 mg nicorandil orally before PCI and received oral nicorandil treatment (15 mg/d,three times daily) for 3 days.QT disperse (QTd),correct QTd (QTcd) and the occurrence rate of ventricular arrhythmia were compared between two groups.Results QTd at 6,24,48 and 72 hours ((70.6 ± 4.4),(67.2 ± 5.3),(55.7 ± 8.5),(48.2 ± 8.2) ms,respectively) after PCI was significantly lower in the experiment group than those of control group ((77.1 ±7.1),(71.3 ± 6.5),(65.1 ± 8.1),(57.2 ± 5.4) ms,all P 〈 0.05).The level of QTd was also significantly lower in the experiment group at 6,24,48 and 72 hours ((77.5 ± 7.7),(67.7 ± 8.6),(61.2 ± 7.5),(52.9 ± 8.4) ms,respectively) after PCI c omared to those of control group ((88.6 ± 8.1),(79.2 ± 7.8),(74.4 ± 7.4),(69.6 ± 8.6) ms,all P 〈 0.05).There was no significant difference in the incidence of reperfusion arrhythmia during PCI procedure between the two groups.The prevalence of the ventricular premature beat in the experiment group (25/60,41.7%) was significantly lower than in the control group (45/60,75.0%) within 3 days after PCI (P 〈 0.01),the prevalence of the no sustained ventricular tachycardia and ventricular fibrillation in the experiment group (6/60,10.0%) was also significantly lower than in the control group (18/60,30.0%,P 〈0.01) within 3 days after PCI.Conclusions Nicorandil use prior and post PCI could decrease the occurrence rate of ventricular arr
