Type 2 diabetes and cardiovascular disease: Have all risk factors the same strength?

Diabetes mellitus is a chronic condition that occurs when the body cannot produce enough or effectively use of insulin. Compared with individuals without diabetes, patients with type 2 diabetes mellitus have a considerably higher risk of cardiovascular morbidity and mortality, and are disproportionately affected by cardiovascular disease. Most of this excess risk is it associated with an augmented prevalence of well-known risk factors such as hypertension, dyslipidaemia and obesity in these patients. However the improved cardiovascular disease in type 2 diabetes mellitus patients can not be attributed solely to the higher prevalence of traditional risk factors. Therefore other non-traditional risk factors may be important in people with type 2 diabetes mellitus. Cardiovascular disease is increased in type 2 diabetes mellitus subjects due to a complex combination of various traditional and non-traditional risk factors that have an important role to play in the beginning and the evolution of atherosclerosis over its long natural history from endothelial function to clinical events. Many of these risk factors could be common history for both diabetes mellitus and cardiovascular disease, reinforcing the postulate that both disorders come independently from "common soil". The objective of this review is to highlight the weight of traditional and non-traditional risk factors for cardiovascular disease in the setting of type 2 diabetes mellitus and discuss their position in the pathogenesis of the excess cardiovascular disease mortality and morbidity in these patients.

Microvascular complications and risk factors in patients with type 2 diabetes

Realizar un estudio prospectivo en sujetos con diabetes mellitus tipo 2 (DM2) sin complicaciones microvasculares, analizando la asociación entre varios factores de riesgo al inicio y el desarrollo de complicaciones microvasculares durante el seguimiento. Métodos Estudio prospectivo, observacional en 376 sujetos con DM2 incluidos en 2004. El objetivo clínico final fue la excreción urinaria de albúmina (EUA) > 30mg/24h y/o presencia de retinopatía al final del seguimiento en 2007. Basalmente las variables fueron: edad, sexo, duración de la diabetes, glucosa plasmática en ayunas, hemoglobina glucada (HbA1c), presión arterial sistólica y diastólica, peso, talla, índice de masa corporal, circunferencia de la cintura, colesterol total, triglicéridos, colesterol unido a lipoproteína de alta densidad (c-HDL), colesterol unido a lipoproteína de baja densidad (c-LDL), proteína C reactiva de alta sensibilidad (PCR-as), fibrinógeno, EUA, creatinina, tabaquismo, ejercicio, consumo de alcohol, utilización de medicación hipoglucemiante, hipolipemiante e hipotensora, y otros datos relacionados con los antecedentes familiares de diabetes y factores de riesgo. Resultados Al final del seguimiento 95 sujetos (25,2%) desarrollaron una complicación microvascular. En el análisis de regresión logística, los principales factores de riesgo independientes fueron la EUA > 12mg/24h (odds ratio [OR]: 6,12; p=0,000), la PCR-as > 3mg/l (OR: 3,00; p=0,004) y la hipertensión (OR: 2,43; p=0,023). Conclusiones Los niveles de EUA superiores a 12mg/24h, la PCR-as > 3mg/l y la presencia de hipertensión fueron factores de riesgo independientes para el desarrollo de complicaciones microvasculares en los sujetos con DM2 estudiados (AU)

In logistic regression analyses, the main independent risk factors were UAE >12mg/24h (odds ratio [OR]: 6.12; P=.000), hs-CRP> 3mg/L (OR: 3.00; P=.004), and hypertension (OR: 2.43; P=.023).ConclusionsUAE levels higher than 12mg/24h, hs-CRP >3mg/L, and presence of hypertension were all independent risk factors for development of microvascular complications in patients with T2DM studied (AU)
