Heart failure is a complex clinical syndrome and pediatric heart failure (PHF) has a high mortality rate. Early diagnosis is crucial for treatment and management of PHF. In clinical practice, various tests and examinations play a key role in the diagnosis of PHF, including continuously updated biomarkers, echocardiography, and cardiac magnetic resonance imaging. This article focuses on summarizing relevant research on biomarkers, examinations, combined testing, clinical models, and the grading and staging of PHF diagnosis, aiming to provide insights and directions for the diagnosis of PHF.
心力衰竭是一组复杂的临床综合征。儿童心力衰竭（pediatric heart failure, PHF）具有较高的病死率。早期诊断对于PHF的治疗和管理至关重要。在临床实践中，各种检验和检查在PHF的诊断中扮演着关键角色，包括不断更新的生物标志物、超声心动图、心脏磁共振等。该文重点梳理PHF诊断的生物标志物、检查、联合检测及临床模型、分级及分期的相关研究，期望为PHF的诊断提供思路和方向。.
