摘要
目的:探讨再发性心肌梗死(recurrent myocardial infarction,RMI)的临床特点。方法:回顾性分析43例RMI(RMI组)和185例初发心肌梗死(初发梗死组)患者的临床资料。结果:与初发梗死组比较,RMI组患者的心电图表现多样,不典型改变明显增加(P<0.05)。RMI组较初发梗死组的左心室舒张末期内径显著增大(P<0.01),而射血分数、左心室短轴缩短率则显著降低(分别为P<0.01,P<0.001);梗死前后心绞痛发生率、室性心律失常、心力衰竭和心源性休克发生率增高、病死率显著增高(P0.05～0.01)。结论:再发性心肌梗死的心电图表现多不典型,并发症增加,病死率较高。对有心肌梗死病史的心绞痛患者,警惕其心电图变化,及时查心肌酶谱有助于及早确诊,改善患者的预后。
Objective： To study the clinical characteristics of recurrent myocardial infarction （RMI）. Methods ： Clinical data of 43 patients with RMI （ RMI group） and 185 patients with primary myocardial infarction （primary myocardial infarction group） were compared and analyzed retrospectively. Results： Compared with primary myocardial infarction, the change of electrocardiograms of RMI were various and atypical （ P 〈 0. 05 ）. Left ventricular diastolic diameter increased markedly （ P 〈 0. 01 ）, but ejection fraction and left ventricular short-axis shortening decreased ohviously （P 〈 0.01, P 〈 0. 001 ） . Angina pectoris before and after infarction, ventricular arrhythmia, heart failure, cardiogenic shock, and death were more often in RMI group than in primary myocardial infarction group （ P 〈 0. 05 -0. 01 ）. Conclusion： Majority electrocardiograms of RMI have no typical characteristics. Complications increased, and death rate is higher in RMI group. In a patient with angina pectoris and history of previous myocardial infarction, the changes of electrocardiogra,n need to he cautious. Checking myocardial zymogram at time is helpful to make definite diagnosis earlier and improve prognosis.
