Background and aims: Two scores exist to assess the benefits and risks of antithrombotic therapy in patients with atrial fibrillation: CHADS(2) [for Congestive heart failure, Hypertension, Age over 75, Diabetes mellitus; and 2 points for a history of Stroke] and HEMORR(2)HAGES [for Hepatic or renal failure, Ethanol abuse, Malignancy, Older (age over 75), Reduced platelet count or function, 2 points for Rebleeding risk Hypertension (uncontrolled), Anemia, Genetic factors, Excessive fall risk (including neurodegenerative and psychiatric disorders) and history of Stroke]. The potential value of using both scores routinely was studied in order to guide the choice of antithrombotic therapy for geriatric patients. Methods: Retrospective calculation of CHADS2 and HEMORR(2)HAGES scores and discharge treatment were collected for all patients with atrial fibrillation during a six-month period. All files were analysed when there were differences between therapeutic choices and the results of analysis of combining the two scores. Results: 83 patients were identified. Their mean age was 89.2+/-4.9 years and 30% of them were on oral anticoagulants on discharge. Usual prescription habits of oral anticoagulants correlated strongly with each of the scores and with the difference between the two scores. The clinical usefulness of using the two scores seemed poor since they indicated that two-thirds of the patients had a similar risk of hemorrhagic and ischemic events. Conclusions: Based on this preliminary study, the CHADS(2) and HEMORR(2)HAGES scores are associated with the prescription of oral anticoagulants, but their routine use may not significantly change the choice of antithrombotic therapy for patients with atrial fibrillation.
