Prevalence of vascular disease in metabolic syndrome using three proposed definitions

CVD prevalence was increased in the presence of MetS irrespective of the definition used. However, this increase was more pronounced when the NCEP-ATP-III and AHA/NHLBI criteria were implemented compared with the IDF definition. Furthermore, the IDF definition included a large proportion of subjects who did not have increased CVD prevalence compared with the whole study population. These findings may have implications regarding which definition should we use to diagnose the MetS.
