Investigadores del estudio de Framingham publican en "JAMA" que la obesidad aumenta en un 52% el riesgo de fibrilación auricular, por lo que se espera que la incidencia de este tipo de arritmia aumente en los próximos años debido al aumento de la prevalencia de la obesidad en los países occidentales.
Los autores examinaron datos del estudio de Framingham en busca de una relación entre el índice de masa corporal (IMC) y el riesgo de fibrilación auricular. El grupo de estudio incluyó a 5.282 participantes sin arritmia al inicio de la investigación. Durante los 13,7 años de seguimiento medio, 526 participantes desarrollaron la arritmia. Los varones obesos tuvieron un riesgo de desarrollarla un 52% mayor que los de peso normal. En mujeres, el incremento del riesgo fue del 46%.
