Current methos of treatment of oncological pathology significantly increase survival rates and patients’ lifespan. However, treatment of malignant tumors leads to development of adverse reactions decreasing its effectiveness and negatively affecting quality of life and survival. It was shown that short- and long-term cardiovascular complications significantly affect the results of therapy.The article presents data on current scientific research in cardio-oncology touching on the problems of cardiotoxicity, concomitant cardiological disorders in oncological patients, cardiac rehabilitation, and patients’ quality of life. The importance of multidisciplinary approach in the context of reducing the risk of cardiovascular complications is demonstrated.
