Impact of the covid-19 pandemic on clinical-surgical outcomes in myocardial revascularization surgery: integrative review

Abstract

To describe the clinical and surgical studies of patients with coronary artery disease (CAD) undergoing myocardial revascularization (CABG) surgery in three years before and three years after the start of the covid 19 pandemic. Method: Integrative review in indexed journals in the databases EMBASE, SCOPUS (Elsevier), MEDLINE (Medical Literature Analysis and Retrieval System online), PUBMED (Central - PMC), Web of Science, Virtual Public Health Library (VHL/BIREME).  The guiding question was developed using the Population, variable, outcome (PVO) strategy. The search occurred on the journal portal of the Coordination for the Improvement of Higher Education Personnel (CAPES), during June 2023. Results: 21 studies were selected, with a sample composed mostly of males, with an average age of 67.59. The global average mortality rate was 1.84%. The main comorbidities found were high blood pressure, diabetes, dyslipidemia, and obesity. The main postoperative complication of MR surgery was bilateral pneumonia in patients with COVID-19. Conclusion: The advent of the Covid-19 pandemic increased the morbidity and mortality of patients with CAD, whose modifiable risk factors were predominantly present. Furthermore, patients who underwent MRI, especially with CPB, were more likely to die due to complications from the disease.
