Cardiological complications of oncological treatment, including the most serious of them cardiotoxicity and heart failure, constitute a significant and still unsolved clinical problem. A history of hypercholesterolaemia and coronary artery disease in cancer patients, is one of the risk factors for cardiotoxicity. In recent years, a protective effect of statin treatment on the development of heart failure in cancer patients has been observed. ANTEC (Atherosclerosis iN chemoTherapy-rElated Cardiotoxicity) is a prospective observational study aimed at assessing the impact of the advancement of atherosclerotic lesions in the coronary arteries assessed in computed tomography on the development of left ventricular systolic dysfunction in cancer patients at high risk of myocardial damage. A group of 80 patients diagnosed with cancer before starting high-dose anthracycline chemotherapy (doxorubicin ≥ 240 mg / m2 or epirubicin ≥ 600 mg / m2 body weight), without a history of heart failure and coronary artery disease, will be included in the study. The total follow-up of patients was planned for 12 months. The primary endpoint is time to onset of left ventricular systolic dysfunction as assessed by echocardiography. The secondary composite endpoints include all-cause death, cardiovascular death, myocardial infarction, and stroke. Additionally, the assessment will include: the severity of atherosclerotic changes in the coronary arteries and the calcification index in computed tomography, the percentage decrease in left ventricular ejection fraction, GLS (global longitudinal strain) in echocardiography, and changes in the concentration of biomarkers involved in inflammatory and atherosclerotic processes. This is the first study of this type, which we hope will contribute to a better understanding of the pathophysiology of cardiotoxicity development and to changing the standards of management of oncological patients and improving survival in this group of patients.
