Oncocardiology has emerged as a discipline in response to the rapidly growing number of patients with a combination of cancer and cardiovascular disease. The important role of cardiovascular disease in increasing the risk of surgical interventions is now undisputed. It is reported that cardiac complications occur in at least 30% of surgical patients with pre-existing circulatory pathology. Reducing cardiac complications in oncosurgery is one of the most pressing problems of modern medicine. It is achieved by careful assessment of perioperative status of cardiovascular system, functional assessment of organs and systems, comparison of risks of complications development with preventive measures, careful selection of patients, use of minimally invasive surgical technologies, minimisation of stress impact of surgical intervention on the organism. The purpose of this manuscript: to describe a clinical case of early diagnosis of an acute cardiovascular complication in a cancer patient. An important role in the planning of combined treatment of oncological patients belongs to the determination of functional reserves and risks of cardiovascular complications, as well as their prevention. The prognosis for life is determined not only by oncological disease, but also by the presence of cardiovascular pathology, its stage and degree of compensation.Keywords: oncosurgery, cardiovascular complications, functional diagnostic methods.
