| Abstract | Background Anthracycline-based chemotherapy represents a cornerstone treatment for a number of common cancers, including breast cancer, lymphoma, and sarcoma. However, anthracycline-induced cardiotoxicity remains a significant concern, often presenting as a decline in cardiac function which can ultimately lead to heart failure (HF) or asymptomatic left ventricular dysfunction, in up to 10–15% of patients.Sodium-glucose transport protein 2 inhibitor (SGLT2i) therapies have been demonstrated to reduce the incidence of HF in high-risk non-cancer patients. Preliminary retrospective data suggest their role in mitigating the incidence of HF during or after anthracycline treatment Methods The EMPACARD-PILOT trial was a prospective case‒control study involving breast cancer patients scheduled to undergo anthracycline-based chemotherapy in a 4-cycle protocol of 60 mg/m2 doxorubicin. We used the HFA/ICOS risk score to identify patients at high or very high risk of cardiotoxicity. Patients with diabetes mellitus or stable heart failure with preserved ejection fraction (HFpEF) were prescribed empagliflozin (10 mg per day), starting seven days before the administration of anthracyclines and continuing for a period of six months. Those not meeting these criteria served as controls. The primary endpoint was cancer therapy-related cardiac dysfunction (CTRCD) incidence. CTRCD was defined as either a decrease in left ventricular ejection fraction (LVEF) of at least 10% to a final value below 50% or a reduction in global longitudinal strain (GLS) of at least 15% from baseline at any point during the study. The secondary endpoints included mortality and hospitalization due to cardiovascular causes or clinical heart failure. Exploratory endpoints included increases in serum troponin and NT-proBNP levels and a decrease in the glomerular filtration rate (GFR). The safety endpoints tracked includedketoacidosis, hypoglycemia, sepsis, neutropenic fever, and urinary tract infections. Results During the enrollment period, 785 breast cancer patients were analysed. Of these, 107 met the inclusion criteria, and 76 subsequently provided informed consent. The study was conducted with comparable adherence rates of 81.5% in both the empagliflozin group (n = 38) and the control group (n = 38). The follow-up data from 62 patients revealed a significant reduction in the primary outcome within 6 months for the empagliflozin group compared with the control group (6.5% vs. 35.5%, p = 0.005), with a relative risk of 0.18 (95% CI: 0.04–0.75). Compared with the control treatment, treatment with empagliflozin also significantly preserved the ejection fraction at 6 months follow-up (56.8% ± 5.8% vs. 53.7% ± 6.7, p = 0.029). However, there were no significant differences between the groups in terms of NT-proBNP, cTnI, clinical heart failure, GFR, or mortality/hospitalization due to heart failure. Conclusion Empagliflozin is associated with reduced incidence of CTRCD in high-risk patients treated with anthracyclines. These data should serve as the foundation for a clinical trial to test whether SGLT2 inhibitors can reduce the incidence of heart failure in this patient group. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
