Abstract

BACKGROUND: Underuse and an inadequate range for the international normalized ratio (INR) for warfarin use are still problems in the management of the patients with atrial fibrillation (AF) in Japan. METHODS AND RESULTS: From January to July 2009, a total of 7,937 AF patients [5,468 men (68.6 ± 10.0 years) and 2,469 women (72.2 ± 9.0 years)] were registered from 158 institutions for the J-RHYTHM Registry. Overall, 34.2% of the patients were over the age of 75. The associated cardiovascular diagnoses were hypertension in 59.1%, coronary artery disease in 10.1%, cardiomyopathy in 8.3%, valvular heart disease in 13.7% and artificial cardiac valves in 3.1% of the patients. The type of AF was paroxysmal in 37.1%, persistent in 14.4%, and permanent in 48.5%. Overall, 87.3% of patients were taking warfarin (2.9 ± 1.2mg/day), of whom 66.0% had an INR between 1.6 and 2.6, and 35.4% were in the INR range from 2.0 to 3.0 at the time of registration. Aspirin was prescribed in 22.3% of cases. The CHADS2 score was 0 in 15.7% of patients, 1 in 34.0%, and ≥ 2 in 50.3%. CONCLUSIONS: At present, warfarin is used extensively in patients with AF whose stroke risk is relatively low (ie, in Japan) and half of them had CHADS2 scores of 0 to 1 (UMIN Clinical Trials Registry UMIN000001569).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
