The psychological well-being of nursing staff is a significant determinant of the efficiency and quality of health care delivery to patients. Consequently, it is of paramount importance for public health. Purpose. This study employed data mining techniques to identify predictors of cardiovascular events in the nursing staff exposed to stress in the educational environment. Materials and Methods. The experiment involved 476 nurses (mean age 47.3 ± 3.2 years), who were enrolled in advanced training courses. The research was conducted in the following age groups: 20–29 years, 30–39 years, 40–49 years, 50–59 years, and 60 years and older. An increase in systolic blood pressure by more than 10 % above the norm during the exam was identified as a sign of stress that could potentially precipitate a cardiovascular event. The values recorded for the subjects during the study sessions were taken as the norm. The following factors were identified as parameters that influence the risk of cardiovascular events in the subjects: work capacity and cognitive abilities during the study sessions and the exam, response of the cardiovascular system to stress, professional and life experience, and body composition. The data obtained were processed using the random forest method. Results. The research found that in subjects aged 20–49 years, the risk of stress and cardiovascular events is influenced by work efficiency and psychological stability; from the age of 40 onwards, body composition is gaining more importance, which is indicative of the ageing processes in the body. At the age of 60 years and older, all nurses are experiencing stress in the non-standard conditions of the exam. The article presents recommendations for the organization of the educational process with the aim of reducing the risk of cardiovascular events in medical staff undergoing training. The findings can be used to resolve issues pertaining to risk management in the organization of the educational process in the context of professional training and retraining of nursing staff.
