Successful Diet and Exercise Therapy as Evaluated on Self-Assessment Score Significantly Improves Endothelial Function in Metabolic Syndrome Patients

BACKGROUND Simple office-based counseling for diet and exercise does not appear to positively affect success rates in metabolic syndrome (MetS) patients. The utility of the lifestyle modification self-assessment score (Self-AS) in the improvement of endothelial function by office-based counseling for patients with MetS was investigated. METHODS AND RESULTS Patients with MetS (n=207) and age- and sex-matched individuals without MetS (n=124) were enrolled in this cross-sectional study. Endothelial function was assessed using reactive hyperemia-peripheral arterial tonometry index (RHI). Patients with MetS had significant endothelial dysfunction compared with those without MetS (RHI, 0.502±0.178 vs. 0.614±0.229; P
