Coronary bypass surgery on the background of Covid-19. A clinical case

COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has had a huge impact on the health of the world's population. Due to the high contagiousness and rapid spread of the infection, on March 11, 2020, the World Health Organization (WHO) announced the beginning of a pandemic. Meanwhile, despite the COVID-19 pandemic, coronary heart disease is one of the most common diseases in the world and still ranks first in the structure of mortality. Currently, one of the optimal and most effective methods of surgical treatment of coronary heart disease with atherosclerotic lesions of the coronary bed is direct myocardial revascularization — coronary bypass surgery. However, cardiac surgical interventions during the COVID-19 pandemic are associated with certain risks. Active infection is a serious aggravating factor that can lead to the development of complications and death. This article presents a clinical case of the death of a 65‑year-old patient after elective coronary artery bypass grafting, where previously undiagnosed COVID-19 was detected in the early postoperative period.
