《第二版心力衰竭通用定义(2026)》解读OA

In 2026,the American Heart Association,American College of Cardiology,European Society of Cardiology,and World Heart Federation jointly published the Second Universal Definition of Heart Failure(2026).The updated document moves away from rigid left ventricular ejection fraction(LVEF)cutoffs for defining heart failure phenotypes and integrates assessment by incorporating clinical evidence.It also proposes a classification of heart failure causes independent of heart failure phenotype,and further clarifies the clinical terminology of improvement,remission,recovery,worsening,and decompensation and its definitions.This article mainly interprets the Second Universal Definition of Heart Failure(2026)focusing on the universal definition of heart failure,heart failure staging and phenotypic identification,etiological classification of heart failure,clinical terminology,and dynamic management,and analyzes its application value in diagnostic expression,tiered diagnosis and treatment,and standardized clinical research variables in the clinical practice in China.
