Se sabe que la obesidad constituye un factor de riesgo tanto de cardiopatía isquémica como de colelitiasis. Los autores investigaron una posible asociación entre estas dos últimas enfermedades en un grupo de 119 pacientes con cálculos biliares detectados mediante ultrasonografía y 354 controles sin colelitiasis.
La prevalencia de cardiopatía isquémica fue casi del 16% entre los primeros, frente a tan sólo un 4,5% entre los controles. El estudio confirma, asimismo, que un índice de masa corporal de 30 o superior es el principal factor de riesgo de cálculos biliares.
