摘要: 目的：系统综述氯氮平(Clozapine, CLZ)所致QTc间期延长的研究进展，为其临床安全用药提供参考。方法：检索国内外相关文献，从流行病学特征、发生机制、影响因素、临床特点及监测管理措施等方面进行归纳分析。结果：CLZ所致QTc间期延长主要与hERG钾通道抑制、自主神经功能紊乱、电解质异常及氧化应激等机制有关，其发生受年龄、性别、血药浓度、联合用药及遗传易感性等多因素影响。QTc延长具有基线依赖性、剂量依赖性和可逆性，规范化的监测与分级干预可有效降低心脏风险。结论：CLZ在TRS治疗中具有不可替代的疗效，但其心脏安全性需引起重视。通过个体化评估与全程监测，可在保障疗效的同时降低QTc延长风险。
Abstract: Objective: To systematically review the research progress of QTc interval prolongation induced by clozapine (CLZ) and provide a reference for its safe clinical administration. Methods: Relevant domestic and foreign literatures were retrieved, and a comprehensive induction and analysis were conducted from the aspects of epidemiological characteristics, pathogenesis, influencing factors, clinical features, as well as monitoring and management measures. Results: QTc interval prolongation induced by CLZ is mainly associated with mechanisms such as hERG potassium channel inhibition, autonomic dysfunction, electrolyte imbalance and oxidative stress. Its occurrence is affected by multiple factors including age, gender, blood drug concentration, combined medication and genetic susceptibility. CLZ-induced QTc interval prolongation presents the characteristics of baseline dependence, dose dependence and reversibility, and standardized monitoring and stratified intervention can effectively reduce cardiac risks. Conclusion: CLZ exerts an irreplaceable curative effect in the treatment of treatment-resistant schizophrenia (TRS), yet its cardiac safety requires close attention. Individualized assessment and whole-course clinical monitoring can reduce the risk of QTc interval prolongation while ensuring the therapeutic effect of CLZ.
