摘　　要：Background Acute stroke （AS） rates in patients over 90 years of age （very elderly） with atrial fibrillation （AF） in the United States（US） are not known. We assessed trends in hospitalizations for AS among very elderly with AF in the US from 2005 to 2014. Methods Weused the nationwide inpatient sample （NIS） from the USA; 2005-2014. AF and AS diagnoses were abstracted using international classifica-tion of diseases, 9th Revision, clinical modification （ICD-9-CM） codes. Results From 2005 to 2014, 3,606,073 hospitalizations of veryelderly with AF were reported. Of these, 188,948 hospitalizations （141,822 hospitalizations in women and 47,126 hospitalizations in men）had AS as the primary diagnosis. Age adjusted AS hospitalizations increased in the total cohort （3217/million in 2005 to 3871/million in2014）, in women （3540/million in 2005 to 4487/million in 2014） and in men （2490/million in 2005 to 3173/million in 2014） （P 〈 0.001）.Anticoagnlation rates increased in women （8% in 2005 to 19.9% in 2014） and in men （8.9% in 2005 to 21.6% in 2014）. AS rates, thoughnumerically lower than the total cohort, showed an increasing trend in anticoagnlated patients as well （all anticoagulated patients： 212/millionin 2005 to 513/million in 2014; anticoagulated women： 224/million in 2005 to 529/million in 2014, anticoagnlated men： 184/million in 2005to 518/million in 2014）. Conclusions There is an increasing trend in AS hospitalizations among nonagenarians with AF in the US despiteimproving utilization of anticoagulants in this patient population. The etiologies driving this alarming trend are unclear and require fur-ther study.
