Awareness of atrial fibrillation in Japan: A large-scale, nationwide Internet survey of 50 000 Japanese adults.

Currently, 3.8% of Japanese adults had high awareness of AF, and we find this value very low. We also noted age-, sex- and region-related differences in awareness level. We believe that awareness initiatives that take into account age- and sex-related differences and prioritize prefectures with lower awareness of AF will be important for preventing cardiogenic cerebral embolism in the future.
