Outcomes
Primary Outcome Measures
Change From Baseline in Flow-Mediated Dilatation (FMD) at Week 12
Brachial artery (BA) FMD equals (=)(maximum diameter minus[-] baseline diameter divided by baseline diameter) times (*) 100 percent (%). Ultrasound images of BA at rest were followed by blood pressure (BP) cuff inflated to at least 50 millimeters of mercury (mm Hg) above participants systolic BP for 5 minutes. Cuff released and reactive hyperaemia was produced. BA was imaged continuously from 30 seconds prior cuff inflation to 2 minutes after cuff deflation. Higher scores indicate improved endothelial function.
Secondary Outcome Measures
