Which is the main reason why this study was carried out on endothelial cells and taking the measurement of the flow-mediated dilation (FMD). The FMD measurement can be seen as a predictor of the incidence of cardiovascular events in adults with no prior cardiovascular diseases (CVD). The Method A randomized and controlled trail was carried out, using 30 he...
