Se sabe que el humo del cigarro afecta numerosos órganos y causa diversas enfermedades, los sistemas particularmente dañados son el cardiovascular y el pulmonar, por el alto estrés oxidativo impuesto por las especies reactivas de oxígeno y nitrógeno que se desprenden o se producen por acción directa del humo del cigarro. Los fumadores tienen además grandes cantidades de neutrófilos en el tractus respiratorio que pueden contribuir a elevar los radicales libres. En el presente trabajo se hizo una revisión de los mecanismos moleculares conocidos que pueden sustentar la patogenia de las enfermedades cardiopulmonares más comunes vinculadas a la acción oxidante de los componentes del humo del cigarro.It is known that cigarette smoke affects numerous organs and causes diverse diseases. The cardiovascular and the pulmonary systems are particularly affected due to the high oxidative stress imposed by the reactive oxygen and nitrogen species that are released or produced by the direct action of cigarette smoke. Smokers have a large number of neutrophiles in the respiratory tract that may contribute to increase the free radicals. In this paper, a review is made on the known molecular mechanisms that may sustain the pathogeny of the most common cardiopulmonary diseases linked to the oxidative action of the components of cigarrete smoke.
