ABSTRACT
Introducción. En España, más del 80% de pacientes con fibrilación auricular (FA) reciben tratamiento anticoagulante oral (TAO), con un seguimiento dentro del ámbito de la atención primaria (AP) del 72% de los pacientes. Estudios recientes demuestran que existe un deficiente control de los pacientes con anticoagulantes orales (ACO). El objetivo de este estudio fue obtener un conocimiento más detallado del estado de control, así como de las patologías que lo indican y están en comorbilidad en los pacientes en tratamiento con ACO antagonistas de la vitaminaK (AVK). Metodología. Estudio observacional retrospectivo/transversal en el que participaron pacientes de una zona básica de salud incluidos dentro del programa TAO durante 2014. Se consideró que el control de INR en pacientes en tratamiento con ACO era inadecuado cuando el porcentaje de tiempo en rango terapéutico (TRT) era inferior al 65% durante un periodo de valoración de al menos 6meses. Resultados. Se incluyeron 368 pacientes, en los que la patología con indicación de anticoagulación oral más prevalente fue la FA no valvular. Se realizaron 5.128 controles, de los cuales 2.359 (46%) estaban fuera de rango terapéutico y 2.769 (54%) estaban en rango terapéutico. El 91% de los pacientes en tratamiento con ACO AVK presentaban un riesgo muy elevado de tromboembolismo. Conclusiones. La indicación de anticoagulación en nuestra población es correcta, asumiendo un riesgo hemorrágico bajo/intermedio en la mayoría de los pacientes. La medición del TRT mediante el método de Rosendaal indica que existe un deficiente control de los pacientes en tratamiento con ACO AVK (AU)
Background. In Spain, more than 80% of patients with atrial fibrillation (AF) receive oral anticoagulant therapy (OAT), and 72% of these patients are followed up in the Primary Care (PC) setting. Recent studies have shown that there is insufficient control of patients on OAT. The objective of the present study was to obtain more detailed information on the state of control of patients on treatment with vitaminK antagonist (VKA) oral anticoagulants (OAC), on the diseases for which the therapy was indicated and on concomitant diseases. Methods. This was a retrospective, cross-sectional, observational study with the participation of patients from a single health area included in an OAT programme throughout 2014. In patients on treatment with OAC, International Normalised Ratio (INR) control was considered insufficient when the percentage time in therapeutic range (TTR) was below 65% during an evaluation period of at least 6months. Results. A total of 368 patients were included in the study, where the most frequent indication for oral anticoagulation was non-valvular AF. A total of 5,128 INR controls were performed, of which 2,359 (46%) were outside the therapeutic range, and 2,769 (54%) were within range. The risk of thromboembolism was very high in 91% of patients on treatment with VKA OAC. Conclusions. The indication for anticoagulation is correct in our population, assuming a low-intermediate risk of haemorrhage in the majority of patients. Measurement of the TTR using the Rosendaal method shows that the control of patients on treatment with VKA OAC is insufficient (AU)
