Statins: Novel Approaches for the Management of Doxorubicin-Induced Cardiotoxicity-A Literature Review

This study aims to evaluate the potential role of statins in preventing doxorubicin-induced cardiotoxicity. With the rising number of cancer survivors and the persistent use of doxorubicin in treatment protocols, there is an urgent need for effective cardioprotective strategies to mitigate long-term cardiovascular complications. Statins, widely used for cardiovascular disease prevention, offer a promising repurposing opportunity due to their pleiotropic effects. A comprehensive review of existing animal and clinical studies was conducted to assess the cardioprotective effects of statins. Key mechanisms such as reduction of oxidative stress, inflammation, and apoptosis were examined, alongside current clinical evidence evaluating their use in patients receiving doxorubicin. Preclinical studies consistently demonstrate that statins significantly reduce doxorubicin-induced cardiotoxicity by modulating multiple cellular pathways involved in oxidative stress, inflammation, and programmed cell death. These findings highlight statins' multifaceted mechanisms of action in protecting cardiac tissue. Numerous observational studies have shown that statin therapy may reduce the incidence and severity of doxorubicin-induced cardiotoxicity, reflected by less decline in left ventricular ejection fraction and a lower risk of heart failure in those receiving statins, but results from randomized controlled trials remain inconsistent. Given the growing burden of cancer therapy-related cardiovascular disease and the established safety profile of statins, further large-scale clinical trials are warranted to confirm their protective role, determine optimal dosing strategies, and facilitate integration into oncology practice. Establishing their utility could improve long-term outcomes for cancer patients vulnerable to cardiotoxicity.
