目的探讨埋藏式心脏复律除颤器(ICD)对恶性室性心律失常患者预后的干预作用。方法103例有Ⅰ/Ⅱa类ICD适应证患者中,21例植入ICD(ICD组),另82例未接受ICD(非ICD组);接受相同的基础治疗。比较两组入选后第3个月,第6个月及第12个月累计死亡率及心脏事件发生率。结果在观察时间达3个月、6个月、12个月时,ICD组累计死亡率和心脏事件发生率明显低于非ICD组。结论ICD能有效终止恶性室性心律失常,用于保护心脏猝死(SCD)高危人群,可使死亡率降低23·17%。ICD可降低SCD高危人群心脏事件发生率,显著提高患者的生存率。
Objective To investigate the intervention effect of buried cardiac defibrillator (ICD) on the prognosis of patients with malignant ventricular arrhythmias. Methods Totally 103 patients with ICD indications of type Ⅰ / Ⅱa were enrolled in ICD group (ICD group), and the other 82 patients who did not receive ICD group (non ICD group) received the same basic treatment. The cumulative mortality and the incidence of cardiac events at the 3rd, 6th and 12th months after the two groups were compared. Results The cumulative mortality and the incidence of cardiac events in ICD group were significantly lower than those in non-ICD group at observation time of 3 months, 6 months and 12 months. Conclusion ICD can effectively terminate malignant ventricular arrhythmia and protect the high risk of sudden cardiac death (SCD) and reduce the death rate by 23.17%. ICD can reduce the incidence of cardiac events in high-risk SCD patients, significantly improve the survival rate of patients.
