[Characterisation of thromboembolic risk in a mexican population with non-valvular atrial fibrillation and its effect on anticoagulation (MAYA Study)].
Gaceta Médica de México 2016 July
OBJECTIVE: To evaluate the risk of stroke and bleeding using the CHA2DS2-VASc and HAS-BLED scores in Mexican patients with atrial fibrillation and to analyze whether the risk score obtained determined treatment decisions regarding antithrombotic therapy.
METHODS: This is an observational, retrospective study in Mexican patients recently diagnosed with atrial fibrillation. The risk of stroke was assessed using the CHA2DS2-VASc scores. The bleeding risk was evaluated using the HAS-BLED score. The frequency of use of antithrombotic therapy was calculated according to the results of the score risk assessment.
RESULTS: A total of 350 patients with non-valvular atrial fibrillation were analyzed. A 92.9% of patients had a high risk (score ≥ 2) of stroke according to the CHA2DS2-VASc score and only 17.2% were treated with anticoagulants. A high proportion of patients with atrial fibrillation (72.5%) showed both a high risk of stroke and a high risk of bleeding based on HAS-BLED score.
CONCLUSIONS: In this group of patients with atrial fibrillation, from Northeast Mexico, there is a remarkably underutilization of anticoagulation despite the high risk of stroke of these patients.
