Purpose of review: The goal of this paper is to summarize the data pertaining to the use of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) for the prevention of cardiotoxicity in patients receiving anthracyclines for cancer treatment. We discuss the potential efficacy of this class of medications, incorporating insights from existing literature and ongoing studies. Recent findings: SGLT2i are a class of medications which were initially developed for treatment of Type 2 diabetes and later extended to treat heart failure with reduced and preserved ejection fraction regardless of diabetes status. There remains a need for effective and safe treatments to preventing cardiotoxicity in anthracycline-treated patients. It has been proposed that SGLT2i may provide protection against the cardiotoxic effects of anthracyclines. Some of the proposed mechanisms include beneficial metabolic, neurohormonal, and hemodynamic effects, renal protection, as well as a decrease in inflammation, oxidative stress, apoptosis, mitochondrial dysfunction and ion homeostasis. Summary: There is emerging evidence from basic science and observational studies that SGLT2i may play a role in the prevention of chemotherapy-induced cardiotoxicity. Randomized controlled trials are needed to conclusively determine the role of SGLT2 inhibitors as a cardioprotective therapy in patients receiving anthracyclines for the treatment of cancer.

Background: Cardiological complications of oncological treatment, including the most serious one, heart failure, constitute a significant and still unsolved clinical problem. A history of dyslipidemia and complications of atherosclerosis, including coronary artery disease, are established risk factors for cardiotoxicity in cancer patients. In recent years, a protective effect of statin treatment on the development of heart failure in cancer patients has been observed. This protocol describes a study aiming to assess the prognostic value of coronary atherosclerosis burden and the CAC score on the onset of cardiac dysfunction associated with cancer therapy. Methods: ANTEC (Atherosclerosis iN chemoTherapy-rElated Cardiotoxicity) is a single-site, prospective, observational study to evaluate the influence of the coronary atherosclerosis and CAC score assessed by computed tomography on the development of left ventricular systolic dysfunction in cancer patients with at least moderate cardiotoxicity risk. A group of 80 patients diagnosed with cancer prior to high-dose anthracycline chemotherapy (doxorubicin ≥ 240 mg / m2 body weight or epirubicin ≥ 600 mg / m2 body weight), without a history of heart failure and coronary artery disease, will be included in the study. Patient follow-up is planned for 12 months. In all patients, coronary computed tomographic angiography (CCTA) will be performed once at the beginning of the study. The primary endpoint is the onset of cancer therapy-related cardiovascular toxicity, defined as mild, moderate, severe and very severe according to ESC 2022 Cardio-oncology guidelines. During follow up, echocardiography with GLS assessment will be performed every three months. Additionally, new biomarkers of atherosclerosis (IL-6, MPO, TNF-alpha) will be measured every 6 months. The study registration identifier on clinicaltrials.gov is NCT05118178. Clinical trials registry: This study is listed on cinicaltrials.gov with identifier NCT05118178.
Interleukin-6, myeloperoxidase, and tumor necrosis factor alpha are proinflammatory cytokines that play a role both in cardiovascular and oncological diseases. The study aimed to prospectively investigate the clinical value of interleukin-6, myeloperoxidase, and tumor necrosis factor alpha as potential biomarkers of cancer therapy-related cardiac dysfunction (CTRCD) in patients receiving anthracycline treatment. A total of 80 patients were included, with 77 (96.25%) followed for an average for 11.5 months. The mean age at baseline was 60.5 years, and 72 (93.51%) were women. Clinical risk factors were documented for all patients, and laboratory assessments, including measurements of IL-6, MPO, and TNF-α, were conducted. All participants also underwent echocardiography with assessment of global longitudinal strain (GLS). In the study group, coronary CT angiography with coronary artery calcium (CAC) score calculation was performed once at the beginning of the study. During observation, any degree of CTRCD was diagnosed in 48 (62.4%) patients. Mild CTRCD occurred in 38 (49.4%) patients, moderate CTRCD was diagnosed in 7 (9.1%), and severe in 3 (3.9%). In patients with high baseline risk, IL-6 levels were significantly elevated compared to those with moderate risk (p = 0.018). Higher levels of IL-6 were found to correlate with an increased grade of CTRCD. In a multivariate repeated measures model of the biomarkers studied, only a higher level of IL-6 was significantly associated with the diagnosis of CTRCD. Among the novel biomarkers studied, we found evidence for IL-6 for its potential use in the detection of cardiac dysfunction related to cancer therapy in patients treated with anthracyclines.
The presence and burden of coronary artery calcium (CAC) is a strong predictor of cardiovascular events. Current guidelines of the European Society of Cardiology (ESC) for cardio-oncology do not recommend the use of the CAC score to determine the status of risk in cancer patients. The aim of this study is to evaluate the presence and burden of CAC on cardiac tomography and the distribution of the cardiovascular toxicity risk factors in patients with moderate and high baseline risk of cancer therapy-related cardiovascular toxicity. The study prospectively included cancer patients, diagnosed and qualified for systemic treatment with anthracycline chemotherapy. Clinical data and blood samples were collected from all patients. Additionally, the echocardiography and coronary computed tomography (CCTA) with the calculation of the coronary artery calcium (CAC) score were performed. A total of 80 patients (mean age 60.5 years, 75 female) were included in the study. The majority of patients (62, 77.5%) had breast cancer, 11 (13.8%) were diagnosed with sarcoma, and 7 (8.8%) with lymphoma. There were 42 (52.5%) patients classified as having moderate (MR) and 38 (47.5%) as having high risk (HR) of cancer therapy-related cardiovascular toxicity according to current ESC guidelines. In comparison with moderate risk, high risk patients were older and more likely to have hypertension, hyperlipidaemia and chronic kidney disease. The mean coronary artery calcium score was significantly higher in the HR group (150.4 vs. 24.8; p = 0.000). Furthermore, cardiac biomarkers were also higher in high-risk patients (p = 0.000). In echocardiographic parameters global longitudinal strain (GLS) was lower (p = 0.012), and diastolic dysfunction was more common in the HR group. However, the left ventricle ejection fraction (LVEF) was similar in the MR and HR groups. In patients at high and moderate risk for cancer therapy-related cardiovascular toxicity, cardiovascular toxicity risk factors were common and more prevalent in the high-risk group. The coronary artery calcium score was also significantly higher in the high-risk group. Assessing the presence and burden of coronary artery calcium is an attractive option to assess additional cardiovascular risk in cancer patients.

Granulomatosis with polyangiitis (GPA) is an antineutrophil cytoplasmic autoantibody (ANCA)-associated systemic vasculitis and is characterized by inflammation of blood vessels. The aim of the present study was to assess cardiac valvular changes in patients with GPA in a cohort of 105 patients followed for a mean of six years. We followed 105 patients (mean age 50.4 years, 67 female) for a mean of 6.2±1.3 years. Echocardiography and laboratory tests were performed in all patients. At baseline, 43% of patients were diagnosed with aortic regurgitation (AR), which was the most common valvular lesion. Moreover, it was the only valvular involvement that significantly increased during observation (p=0.01). In a multivariate model, only D-dimer level was a predictor of AR in this group of patients (OR 8.0 (95% CI: 1.7-38.2, p=0.01). Involvement of the heart valves is a common finding in patients with GPA, but significant valvular disease is a rare complication. The most common valvular disease in this group of patients is AR. Aortic valves are also the most prone to degeneration in the course of the vasculitis.
