The Potential Role of Flavonoids in Ameliorating Diabetic Cardiomyopathy via Alleviation of Cardiac Oxidative Stress, Inflammation and Apoptosis

Diabetic cardiomyopathy is one of the major mortality risk factors among diabetic patients worldwide. It has been established that most of the cardiac structural and functional alterations in the diabetic cardiomyopathy condition resulted from the hyperglycemia-induced persistent oxidative stress in the heart, resulting in the maladaptive responses of inflammation and apoptosis. Flavonoids, the most abundant phytochemical in plants, have been reported to exhibit diverse therapeutic potential in medicine and other biological activities. Flavonoids have been widely studied for their effects in protecting the heart against diabetes-induced cardiomyopathy. The potential of flavonoids in alleviating diabetic cardiomyopathy is mainly related with their remedial actions as anti-hyperglycemic, antioxidant, anti-inflammatory, and anti-apoptotic agents. In this review, we summarize the latest findings of flavonoid treatments on diabetic cardiomyopathy as well as elucidating the mechanisms involved.

Automated summary

Diabetic cardiomyopathy, a major mortality risk factor among diabetic patients worldwide, is characterized by cardiac structural and functional alterations induced by hyperglycemia-initiated oxidative stress. Flavonoids, the most abundant phytochemicals in plants, have been extensively studied for their therapeutic potential in protecting the heart against diabetes-induced cardiomyopathy through their anti-hyperglycemic, antioxidant, anti-inflammatory, and anti-apoptotic actions.
