ABSTRACT

Resumen: En los últimos años, la diabetes mellitus tipo 2 (DM2) ha evolucionado en forma epidémica, experimentando un rápido crecimiento y afectando a millones de individuos a nivel mundial. La cardiopatía isquémica es la principal causa de mortalidad en los pacientes diabéticos, quienes poseen un mayor riesgo cardiovascular respecto a los no diabéticos. La DM2 y la cardiopatía isquémica se caracterizan por ser prevenibles, sin embargo, existen diversos factores de riesgo comunes que contribuyen a su desarrollo. Los mecanismos que explican la ateroesclerosis acelerada y el incremento de riesgo de enfermedades cardiovasculares en los pacientes diabéticos tipo 2 incluyen a la hiperglicemia, dislipidemia y la inflamación del endotelio vascular. La diabetes es resultado de una interacción compleja entre la genética y el medio ambiente. Recientemente se han descrito varios genes implicados en el desarrollo de la diabetes y cardiopatía isquémica y que podrían significar nuevas opciones terapéuticas. En este artículo se revisa la relación entre ambas patologías, los mecanismos moleculares y el descubrimiento de factores de riesgo genéticos comunes y su implicancia en el desarrollo de nuevos blancos terapéuticos.


Abstracts: In recent years, type 2 diabetes mellitus has evolved as a rapidly increasing epidemic and affects millions of people worldwide. Ischemic heart disease (IHD) is the main cause of death among diabetic patients, who have a higher cardiovascular risk than non-diabetics. Both, DM2 and IHD are characterized by being preventable, however there are several common risk factors that contribute to their development. The mechanisms that explain accelerated atherosclerosis and increased risk of cardiovascular diseases in patients with type 2 diabetes mellitus include damage by hyperglycemia, dyslipidemia and inflammation on vascular endothelium. Diabetes is the result of a complex interaction between genetics and the environment, recently, several genes have been identified that appear to be involved in diabetes and ischemic heart disease that could explain its relationship and serve as new therapeutic possibilities. In this article, we review the relationship between diabetes and ischemic heart disease, the molecular mechanisms and the discovery of genetic risk factors common to both diseases and their implication in the development of new therapeutic targets.
