Caracterización de un grupo de pacientes del programa de anticoagulación de una institución de salud y evaluación de los resultados de la escala HAS - BLED y la escala CHA2DS2 – VASc, Medellín (Colombia), 2011 - 2012.

Abstract

Objective : to evaluate the clinical score usefulness of the HAS - BLED and CHA2DS - VASc scales to predict episodes of major bleeding and cardiovascular events. Materials and methods: An analytical study cohort was conducted with the retrospective review of medical records and following a year of evolution of active patients on anticoagulation program in a health center of high level of complexity. Results: A total of 76 patients were collected, 56.6% of whom were female, with a mean age of 73.5 years. The risk to present an event of major bleeding in patients who have a HAS-BLED in the category of high risk is 2.09 times higher compared to the other categories of risk (RR 3.09, 95% CI 1.15 - 8.31). Conclusions : HAS-BLED and the CHA2DS2-VASc scales remain as important tools in predicting bleeding and thromboembolic events respectively; like the CHA2DS2-VASc for bleeding events.
