What is the risk of thromboembolism in patients with atrial fibrillation and flutter?
The risk of thromboembolism in patients with atrial fibrillation and flutter is not well understood. Studies have shown that the risk is higher in those with atrial fibrillation than with flutter, but the exact risk is still unknown. In a 1998 study by Seidl et al., it was found that the risk of thromboembolism in atrial fibrillation was approximately 4.4%, while the risk in atrial flutter was lower, at 1.9%. A 2001 study by Corrado et al. found a higher risk of thromboembolism in atrial flutter (6.3%) than in atrial fibrillation (4.2%). Thus, it appears that the risk of thromboembolism in patients with atrial fibrillation and flutter is higher than the general population, but the exact risk is still not well understood.
