: The incidence and prevalence of AF have increased in recent years , although great variability still exists in Asian countries .
Variability in annual IS risk in patients with AF was apparent between hospital‐ and community‐based studies .
BACKGROUND : Our previous review reported great variability in the incidence and prevalence of atrial fibrillation ( AF ) in non‐Western cohorts , especially from Asian countries ; in recent years , epidemiologic studies on AF have been increasingly reported from Asia .
METHODS : The goal of this up date d systematic review was to present the current knowledge base of AF epidemiology in Asian countries since our previous review .
One-year cardiovascular event rates in Japanese outpatients with myocardial infarction, stroke, and atrial fibrillation. -Results From the Japan Thrombosis Registry for Atrial Fibrillation, Coronary, or Cerebrovascular Events (J-TRACE).-.
BACKGROUND There remains uncertainty about the risk of cardiovascular events in stable out patients with a history of myocardial infa rct ion ( MI ) , stroke , and atrial fibrillation in Japan . METHODS AND RESULTS In the Japan Thrombosis Registry for Atrial Fibrillation , Coronary , or Cerebrovascular Events ( J-TRACE ) , a nationwide prospect i ve cohort of stable out patients with a history of MI ( n=2,291 ) , stroke ( n=3,554 ) , and /or atrial fibrillation ( n=2,242 ) , 1-year follow-up data were available for 7,513 of 8,087 patients ( follow-up rate : 92.9 % ) . The primary endpoint ( death/MI/stroke ) was reported in 3.53 events per 100 person-years ( 95 % confidence interval [ CI ] : 3.11 - 3.99 ) within 1 year . The rates of all-cause death , death from stroke , and death from MI within 1 year were 1.35 ( 95%CI : 1.10 - 1.65 ) , 0.15 ( 95%CI : 0.08 - 0.27 ) , and 0.06 ( 95%CI : 0.02 - 0.14 ) per 100 person-years , respectively . The rate of non-fatal stroke was 1.85 ( 95%CI : 1.55 - 2.19 ) , while that of non-fatal MI was 0.33 ( 95%CI : 0.21 - 0.49 ) . The rate of non-fatal stroke was highest among stroke patients ( 2.95 ; 95%CI : 2.39 - 3.60 per 100 person-years ) , while that of non-fatal MI was similar across all disease categories . Investigator-decided serious non-fatal bleeding events occurred in 0.21 events ( 95%CI : 0.12 - 0.34 ) per 100 person-years . CONCLUSIONS In this large , nationwide Japanese registry , the highest stroke event rate was seen in patients with a history of stroke
