Cardiovascular diseases encompass a variety of conditions

with clinical manifestations mainly including palpitations

chest tightness

chest pain

shortness of breath

dizziness

etc. The heart is a yang organ

with yang qi as its foudnation. If the heart yang is insufficient

it cannot descend and warm water-cold qi

which can lead to upward surging of fluid-pathogen. Therefore

in clinical practice

besides the method of promoting blood circulation and removing blood stasis

the approach of warming yang and resolving fluid retention is also commonly employed. Disease tendency is a dynamic trend in the degree and spatial aspects of the struggle between good and evil qi. It reflects the overall trajectory of disease development

serving as a critical component of TCM syndrome differentiation and treatment

and an important factor affecting clinical efficacy. Analyzing and judging the overall control and subsequent treatment of diseases by disease tendency is of great significance. Linggui Zhugan Decoction (Poria

This article explores the application of these formulas in cardiovascular diseases caused by insufficient heart yang and fluid surging from the perspective of disease tendency

from the dynamic changes of the ascending and descending movements
