Description

El sindrome metabolico es uno de los retos mas intrigantes y fascinantes de la medicina contemporanea. Se trata de una patologia en la que confluyen problemas de distintas areas de la medicina: diferentes grados de hipertension, acumulacion de grasa, insulinoresistencia, estados protrombotico y proinflamatorio, todos juntos en la misma persona. Esta concurrencia de factores hace que la persona tenga un riesgo mucho mayor de sufrir enfermedad cardiovascular o diabetes mellitus tipo 2, que lo que la suma de los factores individuales supondria.Se trata de una "e;enfermedad"e; nueva, que ha llegado a ser un problema de salud publica muy importante en las sociedades desarrolladas y cuya rapida extension se debe fundamentalmente a la adopcion del estilo de vida occidental: fundamentalmente, muy poca actividad fisica e ingesta excesiva de alimentos.Esta obra trata el concepto del Sindrome metabolico en su mas amplio sentido y da respuesta a la multitud de incognitas que todavia presenta esta patologia. Con un enfoque multidisciplinar y un equipo de colaboradores internacionales (Espana, Italia, Japon, Alemania, Estados Unidos, Reino Unido, Finlandia, Australia, etc.) de primer nivel en las distintas areas, escrita integramente en ingles, revisa todos los aspectos relacionados con el Sindrome metabolico, desde el punto de vista de la fisiopatologia molecular y la epidemiologia genetica: obesidad, insulinoresistencia, dislipidemias, hipertension, enfermedad cardiovascular y o
