Abstract: Introduction: atrial fibrillation is one of the most frequent arrhythmias in clinical practice and causes a high number of hospitalizations, establishing a prognosis of dynamic changes in thromboembolic and hemorrhagic risk using the CHA2DS2-VASc and HAS-BLED scales.Objective: to characterize the application of prognostic scales in atrial fibrillation.Method: a narrative review of the available literature was carried out using the analytical synthetic and logical historical methods using articles retrieved from databases such as SciELO, Scopus and ClinicalKey. Articles published mainly in the period 2017 to 2023 were used. A total of 14 references were selected that addressed the main characteristics of the topic in question.Results: a one-point increase in the CHA2 DS2-VASc and HAS-BLED scores represents an increase in the occurrence of events and mortality with both scores, and also represents an increase in the risk of cardiovascular events and mortality. The dynamic calculation of the CHA2DS2-VASc and HAS-BLED scores represents an improvement in the predictive capacity of adverse events with respect to the baseline score. In addition, the dynamic evaluation is clinically more useful than the baseline scores, providing an overall improvement in the net benefit for predicting events.Conclusions: the embolic and bleeding risk scores are important tools for the clinician who prescribes anticoagulation in patients with atrial fibrillation, and recording them in the clinical record is of utmost importance.
