目的:总结分析急性心肌梗死后早期心绞痛发生的相关因素、临床表现及预后。方法:回顾性分析215例急性心肌梗死患者,根据是否出现早期心绞痛分为观察组64例和对照组151例,比较分析两组患者一般资料,临床表现及预后差异。结果:急性心肌梗死后早期心绞痛的发病率为29.8%,发病相关因素中有无Q波坏死、高血压及高血脂等因素在两组间差异有统计学意义(P<0.05),心电图表现有一定的特殊性;观察组给予小剂量的倍他乐克口服治疗,临床总有效率为93.8%。结论:急性心肌梗死后出现早期心绞痛多在14d之内,其中高血压及高血脂患者及心功能较差者易发,及早发现并合理选择治疗方法能够有效降低急性心梗死后早期心绞痛患者的死亡率。
Objective: To summarize and analyze the related factors, clinical manifestations and prognosis of early angina after acute myocardial infarction. Methods: A total of 215 patients with acute myocardial infarction were retrospectively analyzed. According to the presence or absence of early angina pectoris, 64 patients in the observation group and 151 patients in the control group were retrospectively analyzed. The general data, clinical manifestations and prognosis of the two groups were compared. Results: The incidence of early angina pectoris in acute myocardial infarction was 29.8%. There was no Q-wave necrosis in the related factors. There was significant difference between the two groups in the factors of hypertension and hyperlipidemia (P <0.05) A certain degree of specificity; the observation group given a small dose of Betaloc orally, the total clinical effective rate was 93.8%. Conclusion: The early angina pectoris after acute myocardial infarction is mostly within 14 days, of which patients with hypertension and hyperlipidemia and those with poor cardiac function are prone to develop. Early detection and reasonable treatment can effectively reduce the death of patients with early angina after acute myocardial infarction rate.
