Chemotherapy-induced cardiotoxicity is a serious consequence of chemotherapy during cancer treatment that can affect any patient. The purpose of this review is to highlight the development of cardiotoxicity associated with the use of anthracyclines or trastuzumab and to examine prevention and treatment methods using polyphenols, biologically active substances that hold significant therapeutic potential. The main mechanisms of this pathology, modern biomarkers for detection, and the classification and biological activity of polyphenols are discussed. Emphasis is placed on polyphenols found in grapes and their antioxidant potential as a protector of the cardiovascular system.
