目的研讨非ST段抬高性心肌梗死与ST段抬高性心肌梗死的临床特征。方法选取该院2010年7月—2011年7月收治的142例急性心肌梗死的患者,依据心电图的显示有无ST段的抬高进行区别随机分为两组,非ST段抬高性心肌梗死为甲组患者70例,ST段抬高性心肌梗死为乙组患者72例,比较分析两组的临床特征,依据分析的临床特点进行治疗指导。结果甲组患者既往较多患有心绞痛、糖尿病等病史,患者冠状动脉存在侧支循环,较容易发生弥漫性病变。乙组的患者较容易发生心源性休克,心律失常等情况的发生,冠状动脉病变较多发生在单支。统计两组患者的致死率差异无统计学意义。结论非ST段抬高性心肌梗死较常发生于患有糖尿病史的患者,既往存在反复发作的心绞痛病史,冠状动脉变化较多发生与多个分支,较容易并发多个侧支循环,治疗预后情况较差。
Objective To investigate the clinical features of non-ST-elevation myocardial infarction and ST-segment elevation myocardial infarction. Methods A total of 142 patients with acute myocardial infarction who were admitted to our hospital from July 2010 to July 2011 were divided into two groups randomly according to the presence or absence of ST segment elevation on ECG. Non-ST-segment elevation myocardial infarction 70 patients in group A and 72 patients in group B with ST-segment elevation myocardial infarction. The clinical features of the two groups were compared and analyzed, and the treatment guidelines were given according to the clinical features. Results A group of patients with previous history of angina pectoris, diabetes mellitus, patients with coronary collateral circulation, more prone to diffuse lesions. Patients in group B are more prone to cardiogenic shock, arrhythmia and other occurrences, coronary artery lesions occur more often in the single branch. Statistics of two groups of patients with no significant difference in mortality. Conclusion Non-ST-elevation myocardial infarction occurs more frequently in patients with a history of diabetes mellitus, with a history of recurrent angina pectoris, multiple coronary artery changes and multiple branches, and is associated with multiple collateral circulation. The prognosis The situation is poor.
