目的探讨急性心肌梗死后新发房颤与继发恶性心律失常之间的相关性。方法选取医院收治的急性心肌梗死患者120例,治疗结束后对其进行1年随访,观察比较新发房颤与继发恶性心律失常与未发生房颤患者的一般资料差异。结果经观察发现,急性心肌梗死后新发房颤中恶性心动过缓、室性心动过速与未发生房颤恶性心动过缓、室性心动过速比较,差异均有统计学意义(P<0.01)。经多因素Logistic回归分析发现,患有糖尿病、高血压、心功能较差患者,与是否出现新发房颤及恶性心动过缓之间具有相关性,差异有统计学意义(P<0.05)。结论急性心肌梗死后患者有较高几率出现新发房颤与继发恶性心律失常。
Objective To investigate the relationship between new-onset atrial fibrillation and secondary malignant arrhythmia after acute myocardial infarction. Methods A total of 120 acute myocardial infarction patients admitted to hospital were enrolled in this study. One year follow-up was performed after the treatment. The general data of patients with new-onset atrial fibrillation, secondary malignant arrhythmias and without atrial fibrillation were compared. Results The observation showed that the difference of malignant bradycardia, ventricular tachycardia and non-occurrence of atrial fibrillation and ventricular tachycardia in newly diagnosed atrial fibrillation after acute myocardial infarction were statistically significant (P < 0.01). Logistic regression analysis showed that there was a significant difference between patients with diabetes, high blood pressure and poor cardiac function, and with or without new onset of atrial fibrillation and malignant bradycardia (P <0.05). Conclusion Patients with acute myocardial infarction have a higher incidence of new-onset atrial fibrillation and secondary malignant arrhythmias.
