Outline of Final Research Achievements

Accumulating evidence suggests that endothelial dysfunction is an early marker for atherosclerosis. Improvement in endothelial function is associated with a decrease in atherosclerotic vascular diseases. The aim of this study was to assess the effects of dry heating, electrical stimulation and the combination of dry heating and electrical stimulation on the endothelial function in the brachial artery. We measured flow-mediated dilation (FMD) as an index of vascular function before and after 30 min of each trial. A combination of dry heating and electrical stimulation significantly increased FMD in the brachial artery. However, no significant changes were observed after only dry heating or electrical stimulation. This study revealed that the combination of dry heating and electrical stimulation is effective in improving conduit vasodilator function.
