Cardiac sympathetic, urinary and plasma catecholamine effects of active and passive coping were investigated during both low and high stress. Stress intensity was manipulated by varying the work load on a bicycle ergometer. As predicted, T-wave flattening of the ECG - an index of cardiac sympathetic activity - was significantly more pronounced during active coping than during passive coping. This effect did not depend upon the degree of stress. A significant increase in both adrenaline and noradrenaline levels depended upon the combined effects of active coping and high stress. Because high concentrations of circulating catecholamines are thought to be related to cardiovascular pathology, the results suggest that active coping during high stress might involve the highest cardiovascular risks.
在低应激和高应激状态下，研究了主动应对和被动应对对心脏交感神经、尿液及血浆儿茶酚胺的影响。通过改变自行车测力计的工作量来控制应激强度。正如所预测的，心电图T波低平——心脏交感神经活动的一个指标——在主动应对期间比在被动应对期间明显更显著。这种效应不取决于应激程度。肾上腺素和去甲肾上腺素水平的显著升高取决于主动应对和高应激的联合作用。由于循环中高浓度的儿茶酚胺被认为与心血管病理有关，结果表明在高应激期间主动应对可能涉及最高的心血管风险。
