This paper introduces Professor LI Qinghai′s experience in treating hypertrophic cardiomyopathy（heart accumulation）. It is believed that the disease is mostly due to insufficient congenital endowment and acquired disorders

resulting in the deficiency and depletion of heart

spleen and kidney

especially the deficiency of both qi and yin of the heart. When insufficient qi fails to promote blood circulation

and stasis obstructs the vessels

yin-fluid distribution is impaired and phlegm is therefore formulated when fluids accumulate; the heart loses nourishment

while the phlegm and stasis are binded and accumulated in the heart

gradually formulate the myocardial hypertrophy. In treatment

the combination of Chinese and Western medicine is advocated to play the synergistic effect; replenishing method should be taken as priority by supplementing qi and yin and tonifying the spleen and kidney; phlegm and stasis need to be treated together but with emphasis; and insect medicine should be taken fully use of to expel stasis

dissipate masses

unblock the channels and quicken the collaterals. Self-made Si Wei Chong Formula（四味虫方） is suggested to be used throughout the treatment to improve ventricular wall remodeling

and to block or reverse hypertrophic cardiomyopathy.
