Percutaneous coronary intervention (PCI) is an important treatment for patients with coronary atherosclerotic heart disease. Traditional Chinese medicine categorizes the recurrence of angina pectoris after PCI for coronary heart disease (CHD) into "

xiong bi xin tong

(chest impediment and pain)" and "

cu xin tong

(sudden heart pain)" . Prof. Huang Lijuan believes that angina after PCI always belongs to the syndrome of deficiency as the root and excess as the branch. The root is mainly characterized by qi

yin

and yang deficiency

while the excess involves primarily qi stagnation

blood stasis

phlegm turbidity

and cold coagulation. This disease causes damage to all five organs

and the heart is mostly affected

with the liver

spleen

and kidneys as the key. The initial stage is for those who experience recurrent angina pectoris 2 years after PCI. This stage is mainly characterized by qi yin deficiency and heart blood stasis obstruction

with the treatment of supplementing qi and nourishing yin

invigorating blood and resolving stasis

and the best suitable formula is Shengmai Powder (Pulse-Engendering Powder) combined with Xuefu Zhuyu Decoction (Blood Stasis Expelling Decoction). Patients with recurrent angina pectoris within 2-5 years after PCI surgery are in the middle stage. This stage is characterized by severe qi deficiency

blood stasis

phlegm turbidity

and liver stagnation and spleen deficiency. The treatment is to invigorate blood

eliminate phlegm and stasis

regulate the liver and spleen

and replenish qi. The basic formula is Gualou Xiebai Banxia Decoction (Trichosanthes

Chinese Chive and White Wine Decoction) combined with Xiaoyao Powder (Free Wanderer Powder)

with possible adjustments to the formula as needed. Those who still experience recurrent angina after PCI with a course of more than 5 years are in the advanced stage. This stage is mainly characterized by qi and blood stasis

deficiency of heart and kidney yang

and cold coagulation. The treatment focuses on warming the kidney and assisting yang

as well as supplementing qi

invigorating blood

resolving phlegm

and unblocking collaterals. In addition

we attach great importance to the harmony of mind and body

with a particular emphasis on soothing the liver and regulating the spleen

emphasizing the correlation between qi and blood

and the simultaneous treatment of qi and blood. This study comes with proven case records to further explain Prof. Huang’s clincial ideas.
