What is the risk of thromboembolism and stroke in patients with atrial flutter?
The risk of thromboembolism and stroke in patients with atrial flutter has been evaluated in relatively few studies compared with AF. Clinical risk stratification for stroke should be done using the CHA2DS2VASc-score. If the diagnosis of AF or atrial flutter is intermediate (CHA2DS2VASc score = 1 in males and = 2 in females) or high risk (CHA2DS2VASc score 2 in males and 3 in females), monitoring of AHRE evolution is advised, as well as clinical follow-up to evaluate if AHRE >24 h and/or clinical AF develops, as well as changes in patient status/clinical profile (eg, heart failure). Individual considerations should also be taken into account when considering prescription of OAC.
