La ciudad de México es una de las ciudades más contaminadas del planeta. Un nuevo estudio, presentado hoy día en la conferencia de biología experimental, ha concluido que la inflamación cardiaca puede ser causada por las partículas en el aire contaminado.

Los investigadores de la Universidad de Montana, EEUU y el Instituto Nacional de Pediatría, México, D.F., examinaron los corazones de 21 jóvenes – edad promedio de 18 años – que habían fallecido accidentalmente en la ciudad de México. Estudiaron la reacción inflamatoria del cuerpo contra las partículas y las endotoxinas – pedazos de bacteria muerta que sujetadas a las partículas en el aire.

Concluyeron que la contaminación ambiental puede crear una reacción inflamatoria, hasta en los jóvenes. Aunque la inflamación no parecía hacer daño inmediato, los investigadores adviertan que la inflamación crónica puede manifestarse en problemas cardiacos en el futuro.

Los investigadores son Rodolfo Villarreal, Juan Palacios, Keith Parker y Lilian Calderón.
