Abstract：The collateral disease theory believes that heart failure belongs to heart collateral disease and it suggests that the basis of pathogenesis of heart failure is heart-collateral qi deficiency and weak pulse at yang；the core of progression is stasis obstructing the collateral vessels，and the final pathological change is concretions formed by long-term accumulated pathogen in the collateral vessels. The theory holds that the treatment should respectively prioritize the methods of warming yang， resolving stasis and inducing diuresis based on the principle that “collateral needs to keep unobstructed” and the pathological characteristics of heart failure in terms of qi，blood and water aspects. Specifically，the treatment should mainly tonify qi and warm yang， and supplement deficiency and nourish collaterals， supplemented with activating blood and resolving stasis， and inducing diuresis and unblocking the collaterals. With simultaneous treatment of unblocking and supplementation，the root and branch are treated simultaneously to unblock the heart collaterals，and move qi and blood so that the disease is cured.
