Un artículo publicado en el "American Heart Journal" concluye que Helicobacter pylori, bacteria causante de úlceras gastroduodenales y cáncer de estómago, también parece incrementar el riesgo de enfermedades vasculares.
Médicos italianos del Hospital San Filippo Neri de Roma publican una revisión de 17 estudios que han analizado el papel de cepas de H. pylori CagA-positivas en pacientes con enfermedad vascular cardíaca o cerebral. La revisión incluye en total a más de 6.000 pacientes.
Trece de los estudios encontraron una relación estadísticamente significativa entre las cepas de la bacteria y la enfermedad cardíaca, algo que no se observó en las cepas CagA-negativas. Otros 4 estudios encontraron asociación significativa entre cepas de H. pylori CagA-positivas y enfermedad cerebrovascular, pero no así entre esta y las cepas negativas.
En conclusión, escriben que las cepas CagA-positivas de la bacteria están asociadas a un modesto, aunque significativo, incremento del riesgo de enfermedad cardiovascular.
