: Recent advances in the treatment of breast cancer have resulted in improved overall cancer survival; however, cancer therapy related cardiac dysfunction is considered a major adverse effect of several chemotherapeutic agents, particularly anthracyclines. Hence, there is a need to develop proper cardioprotective strategies to limit myocardial injury following chemotherapy. : To evaluate the effect of statin therapy on prevention of anthracycline- induced cardiotoxicity in female patients with breast cancer. : The current study is a prospective, randomized, single-blind, placebo-controlled trial in which we enrolled a total of 110 female patients with newly diagnosed breast cancer who received anthracycline based chemotherapy. Patients were randomly assigned in 1:1 ratio into two groups, study group in which patients received 40 mg of oral atorvastatin and control group in which patients received placebo. A comprehensive echocardiographic examination was performed to all patients prior to receiving the chemotherapy and after 6 months, assessment of LV ejection fraction was done by 3D-echocardiography. All echocardiographers were blinded to all the patients’ characteristics and assignment to either group. : The mean age of patients assigned to the control group was 49.8±10.51 years old, while patients assigned to the intervention group had mean age of 47.84± 9.16 years old, both the control group and the intervention group were similar in demographic data and baseline clinical characteristics. There was a highly significant difference between the two groups regarding both the absolute LVEF assessed by 3D- echocardiography at 6 months and the percentage of change compared to baseline values, patients assigned to the control group had mean LVEF of 52.92% at 6 months with percentage of change reaching -7.06%, while those assigned to the intervention group had mean LVEF reaching 56.22% at 6 months with a percentage of change reaching -3.64% (P-value: 0.008 and 0.004 for the absolute value and percentage of change respectively). There was a significant difference between the two groups regarding incidence of development of cancer therapy related cardiac dysfunction (CTRCD); defined as drop in LVEF more than 10% and to a value below 53% assessed by 3D echocardiography, among the control group 15 patients (30%) developed CTRCD after 6 months from starting Anthracyclines based chemotherapy, while, among the intervention group only 6 patients (12%) developed CTRCD.
