摘要: As a stressful lifestyle has been associated with coronary heart disease, this study aim to evaluate how two tests influence endothelial-dependent vasodilation evaluated by flow-mediated dilation (FMD) of the brachial artery. FMD following 5 min occlusion forearm was in young healthy volunteers measurements artery diameter and blood flow (BABF) using ultrasound before during mental arithmetic task (MAT), cold pressure test (COP). MAT COP increased similar degree (18-21 mmHg). The induced significant reduction compared baseline levels (from 9.3 - 3.9 5.9 3.2%, p < 0.01), as well MAT, which itself did not (10.1 5.0%). However, BABF hyperaemia significantly, ratio significantly reduced both stress ( 0.05). Time-control experiments showed be reproducible that themsel...
