Objective:

to analyze the epidemiological and clinical characteristics of a population with nonvalvular atrial fibrillation (NVAF) treated with oral anticoagulation at Instituto Cardiovascular del Tolima in Ibagué, Colombia.

Reference framework:

NVAF is a prevalent disease in Colombian patients over the age of 60, who are at greater risk of a cerebrovascular accident, which is preventable with anticoagulation treatment. However, complications inherent or secondary to the disease may occur despite treatment.

Methods:

a cross-sectional study which describes the baseline characteristics of a total of 146 participants with NVAF being treated with oral anticoagulants, using information from their clinical charts between 2018 and 2019.

Results:

of the participants, 53% were female, and 57% of the participants had permanent NVAF, this being the most frequent type in the study cohort. Ninety-nine percent were treated with non-vitamin K oral anticoagulants (NOACs) (76% with rivaroxaban), and 1% with a VKA (warfarin). Eighty-nine percent of the participants had a CHADS2 classification between 1-3 and 87% fell in the HASBLED 1-3 categories; of these, 95% did not have a CVA/TIA, 99% did not have a systemic embolism and 97% did not have major bleeds, respectively for each classification. There were no fatal outcomes in any of the patients.

Conclusions:

an association was confirmed between CHADS2, CHADS2VASC2 and HASBLED classifications and CVA/TIA and hemorrhages in the study population (p<0.05). (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2202).
