Role of puerarin in pathological cardiac remodeling: A review

Abstract

Pathological cardiac remodeling normally involves changes in structure, function, and energy metabolism of the heart induced by cardiac injury or load, terminally leading to heart failure. Cardiac remodeling plays an essential role in the progression of cardiovascular disease, thus increasingly identified as an important therapeutic target for heart failure of all pathogenesis. Puerarin, as a natural isoflavone mainly from Pueraria lobata （Willd.）Ohwi, has been developed as injections, eye drops, microemulsions, etc., and is widely used in the clinical treatment of cardiovascular diseases in eastern Asia countries. In recent years, a growing number of studies have shown that puerarin significantly inhibits myocardial hypertrophic growth, myocyte death, fetal gene expression, fibroblast proliferation and activation, improves energy metabolism, promotes post-infarction angiogenesis, and suppresses inflammation and oxidative stress, consequently attenuating or preventing cardiac remodeling in response to multiple stimuli ( e.g., pressure overload, MIRI, MI, Iso, and Ang II stimulation). This review summarized the roles and underlying molecular mechanisms of puerarin in cardiac remodeling induced by diverse etiologies, aiming to help develop novel therapeutic strategies to prevent or reverse pathological ventricular remodeling.
