Present Status of Anticoagulation Treatment in Japanese Patients With Atrial Fibrillation - A Report From the J-RHYTHM Registry -

The Atrial Fibrillation in Turkey: Epidemiologic Registry (AFTER)

“…In our study, while the rate of oral anticoagulant use was 40%, ASA use was approximately 2 times higher. In the J-RYHTHM [6] study which was conducted in Japan, while the rate of anticoagulant use was 87%, the rate of ASA use was found to be 22%. In the subgroup analysis [16] of the same study, 89% of the 6324 patients with non-valvular AF were on warfarin treatment and 23% were on ASA treatment.…”

“…In our country, the studies conducted on AF, stroke and oral anticoagulant usage are mostly unicenter studies with a limited number of patients and CHA 2 DS 2 -VASc score wasn't included [3][4][5]. Since the multicenter studies have been conducted in western and far eastern populations, they do not refl ect the characteristics of the country [6][7][8][9][10].…”

Regional Differences in Frequency of Warfarin Therapy and Thromboembolism in Japanese Patients With Non-Valvular Atrial Fibrillation – Analysis of the J-RHYTHM Registry –

“…13, 14 Briefly, the study protocol conformed to the Declaration of Helsinki and was approved by each of the participating institutions. Anti-thrombotic drugs and dosages were selected at the discretion of the treating physicians.…”

“…13, 14 One of the primary objectives of the J-RHYTHM Registry is to explore variations in the international normalized ratio (INR) of prothrombin time and the quality of anticoagulation between the 10 geographic regions of Japan, and to determine how these variations affect outcome. 13 In the present study, the regional differences in the state of warfarin-based anticoagulation therapy and its outcomes in NVAF patients were examined.…”

Epidemiology, anticoagulant treatment and risk of thromboembolism in patients with valvular atrial fibrillation: Results from Atrial Fibrillation in Turkey: Epidemiologic Registry (AFTER)

“…Even so, most studies investigating AF and stroke have been mostly performed with non-valvular AF patients. This has led to a paucity of detailed epidemiological information regarding risk factors for thromboembolism in patients with valvular AF [3][4][5][6][7][8][9][10]. Although there was a multicenter study that investigated the epidemiology of heart valve diseases in Turkey, this study did not focus on valvular AF patients [11].…”
