ABSTRACT
Introduction. New-onset postoperative atrial fibrillation after cardiac surgery is common, with rates of up to 60%, and has been associated with early and late strokes, but its association with other cardiovascular outcomes is less well known. The aim of this study is to perform a systematic review of studies reporting the prevalence of postoperative AF.
Material and methods. Systematic review structured according to the PRISMA system. After formulating the research question with the PICO system, a search was carried out in different databases for “Atrial Fibrillation after cardiac surgery AND thoracic surgery”. Articles in both Spanish and English were selected, especially those published in the last 5 years. Articles with low scientific evidence were not selected. There was no conflict of interest and the work was carried out taking into account the bioethical principles of all research.
Results. In the end twelve articles were selected in accordance with election criteria for critical reading with the CASPe system. Each of the articles was classified according to author, year of publication, level of prevalence, socio-demographic data and level of SING evidence. The main biases that occurred were selection and publication biases.
Conclusions. The prevalence of postoperative AF is between 30% and 40% of patients undergoing cardiac surgery.
