Тhe concept, risk factors, mechanisms, clinical and epidemiological, and angiographic features of perioperative ischemic injury and myocardial infarction were considered. Perioperative myocardial infarction is one of the most common complications (up to 3.6%) in non-cardiac surgical interventions and is characterized by high in-hospital mortality, reaching 25%. Most patients with this pathology (up to 65%) do not have typical symptoms of myocardial ischemia due to anesthesia and sedation. Pathogenetic mechanisms of perioperative myocardial infarction development continues to be actively studied. A critical increase in myocardial oxygen demand is indicated as the leading cause in some studies. Angiography reveals rupture of the coronary plaque and atherothrombosis in more than half of patients, according to other data. These contradictions point to the need for further epidemiological studies using coronary angiography with a focus on risk factors and triggers of this complication. In addition, the concept of perioperative myocardial injury in recent years has been formulated in the scientific literature. This is understood as ischemic damage that occurs in the first 30 days after surgery. Recent studies have shown that it can occur in 16% of surgical patients and is associated with a 6-fold increase in mortality within 1 month after surgery and a 2.5-fold increase within a year. It is important that perioperative myocardial injury does not include cases of non-ischemic etiology myocardial injury, for example, due to pulmonary embolism, sepsis, or electrical cardioversion. Thus, the assessment and understanding of risk factors for the development of perioperative myocardial ischemia is of great practical importance in optimizing the patient selection and preparation for surgical treatment.

This retrospective study analyzed the structure of complications and mortality cases in 351 patients (men, n = 199; women, n = 152) aged 3389 years with locally advanced abdominal cancer and different cardiovascular risks in the early postoperative period, and two patient groups were formed. The main group consisted of 81 (23.1%) patients who died in the early postoperative period. The comparison group included 270 (76.9%) patients. In total, 311 (88.6%) patients underwent radical surgical intervention, whereas 40 (11.4%) underwent minimally invasive surgical treatment. Perioperative cardiovascular risk was stratified by calculating cardiac risk indices and using the database of the National Program for Improving the Quality of Surgical Care Myocardial Infarction and Cardiac Arrest. Fatal complications in the early postoperative period after surgical treatment of locally advanced abdominal cancer is significantly more often observed in patients with a more pronounced degree of tumor invasion, lymph node lesions, high class according to the standards of the American Society of Anesthesiologists, reduced functional status, prior hormone therapy, and combined anesthesia. The majority of fatal cases were associated with three complications, i.e., ventricular arrhythmias (53%), acute decompensation of heart failure (46%), and multiple organ failure (43%). Approximately 95% of deaths were associated with increased postoperative cardiovascular risk, and 52% were medium-risk cases. Hospital mortality at low risk was noted in 4.9%, average in 27.8%, and high in 32.7% of the patients. In cases with a favorable course, surgical complications were predominant over cardiovascular ones. The use of calculated cardiac risk indices and database of the National Program for Improving the Quality of Surgical Care Myocardial Infarction and Cardiac Arrest confirmed their high ability to predict the development of cardiovascular complications, which are the leading causes of death in the early postoperative period in patients who underwent surgical interventions for locally advanced abdominal cancer.
OBJECTIVE: Study modern approaches to projection and differentiated assessment of cardiovascular risks with extracardiac surgical interventions.MATERIALS AND METHODS: The articles from scientometric database RSCI, PubMed and Scopus for 2005–2022 are analyzed. In total, 39 literary sources were selected; not less than 70% of which were published over the past 5 years. The works, published more than 5 years ago, were allowed to include in the literature review only in case if they were primary sources and highly informative. RESULTS: To predict perioperative risk there is currently a range of general validated scales that help to define patients with a high risk of death and development of complications. These algorithms were developed based on multivariate statistical analysis of a large number of studies and reflect the links between clinical, laboratory and instrumental indicators with perioperative cardiovascular risk and mortality.DISCUSSION: Nowadays there is no opportunity to predict the risk of developing cardiovascular complications and death after surgical intervention with 100% probability. The majority of existing indices and scales has their drawbacks, but complement each other, and their use may significantly help in the decision-making process on patient management tactics. However, data acquired through these means should be considered and taken into account only in the general context of diagnostic process along with conventional diagnostic methods.CONCLUSION: The assessment of patient’s medical status and cardiovascular risk is one of the major tasks in preoperative preparation, which solution requires improvement and standardization of step-by-step algorithms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
