La microalbuminuria explica el incremento de riesgo vascular en pacientes con diabetes y síndrome metabólico

The aim of this study was to determine the impact of the metabolic syndrome on vascular disease risk in patients with type-2 diabetes. A prospective cohort study was carried out. The main dependent variable was the combination of coronary disease, stroke and lower leg amputation. Cox regression modeling was used. In total, 317 patients were followed for a mean of 7.7 years. The prevalence of metabolic syndrome was 87%. Multivariate analysis identified the following as predictors of incident vascular disease: age (relative risk [RR] =1.06, 95% confidence interval [CI], 1.02-1.1; P=.0003), baseline cardiovascular disease (RR=1.8; 95% CI, 1.1-3.0; P=.017), and the simultaneous presence of four metabolic risk factors (RR=5.8; 95% CI, 1.8-18; P=.003). The most predictive factor was microalbuminuria (χ2=5.9; P=.015). Microalbuminuria accounts for the increased risk of vascular disease in patients with metabolic syndrome. In evaluating vascular disease risk in patients with type-2 diabetes, it is more important to consider the total number of metabolic risk factors than the presence of metabolic syndrome alone.
