Se acaba de publicar en Circulation esta interesante controversia sobre cuál podría ser la mejor estrategia en los pacientes que tienen fibrilación auricular y bajo riesgo cardioembólico (CHA2DS2VASc=1 en varones y 2 en mujeres). A favor: Should Patients With Atrial Fibrillation and 1 Stroke Risk Factor (CHA2DS2-VASc Score 1 in Men, 2 in Women) Be Anticoagulated? Yes: Even 1 Stroke Risk Factor Confers a Real Risk of Stroke. En contra: Should Patients With Atrial Fibrillation and 1 Stroke Risk Factor (CHA2DS2-VASc Score 1 in Men, 2 in Women) Be Anticoagulated? The CHA2 DS2-VASc 1 Conundrum: Decision Making at the Lower End of the Risk Spectrum.
