Abstract： According to the Xuanfu Theory， the blockage of Xuanfu (sweat pores) and the binding of blood stasis， phlegm turbidity， and retained fluid will result in the deficiency of heart qi and heart yang， leading to the abnormal distribution of qi，blood，and fluids，which is a key factor in the occurrence and development of heart failure. This article elaborates on the correlation between the onset of heart failure and Xuanfu from the aspects of Xuanfu yang deficiency，qi constraint，phlegm turbidity，retained fluid，and stasis-toxin，proposes a treatment method of supplementing deficiency，resolving constraint，clearing up phlegm and dissolving fluid retention，and resolving toxins and dissolving stasis to open Xuanfu based on the characteristics of ascending， moving， dispersing， removing， and unblocking of wind- dispelling medicine，and enriches the theoretical system of "opening Xuanfu by wind-dispelling medicine" treatment in the diagnosis and treatment of heart failure，so as to provide guidance for clinical medication.
