These results suggest a possible direct vascular benefit of pioglitazone; METHODS AND RESULTS: CIMT was measured in 382 participants at the beginning and up to 3 additional times during follow-up of the Actos Now for Prevention of Diabetes trial. During an average follow-up of 2.3 years, the mean unadjusted annual rate of CIMT progression was significantly (P=0.01) lower with pioglitazone treatment (4.76x10(-3) mm/year; 95% CI: 2.39x10(-3)-7.14x10(-3) mm/year) compared with placebo (9.69x10(-3) mm/year; 95% CI: 7.24x10(-3)-12.15x10(-3) mm/year). High-density lipoprotein cholesterol, fasting and 2-hour glucose, HbA(1c), fasting insulin, Matsuda insulin sensitivity index, adiponectin, and plasminogen activator inhibitor-1 levels improved significantly with pioglitazone treatment compared with placebo (P<0.001). However, the effect of pioglitazone on CIMT progression was not attenuated by multiple methods of adjustment for traditional, metabolic, and inflammatory risk factors and concomitant medications, and was independent of changes in risk factors during pioglitazone treatment; OBJECTIVE: To determine whether changes in standard and novel risk factors during the Actos Now for Prevention of Diabetes trial explained the slower rate of carotid intima media thickness (CIMT) progression with pioglitazone treatment in persons with prediabetes UR - http://dx.doi.org/10.1161/ATVBAHA.112.300346 ER -
