本研究验证了流行病学研究中最能预测冠心病（CHD）发病率的行为属性也最能预测交感自主神经系统（ANS）在应对性能挑战时的觉醒的一般假设。受试者（n = 50）的挑战，以迅速和准确地响应三个任务，涉及感知运动或认知技能，而实验者监测血压，心率和皮肤电位。该假设得到了普遍证实，因为（1）A型受试者比B型受试者显示出指示交感神经ANS唤醒的显著更大的心血管变化，（2）Rosenman和Friedman结构化访谈比Jenkins活动调查更好地预测了这种唤醒，就像CHD中的情况一样，（3）A型人格模式（结构化访谈定义）中最能预测CHD的风格和行为成分也被发现是挑战诱导的交感神经激活的最佳预测因子。讨论了这些结果对改进冠状动脉易感行为的定义、评估和改变的影响。
The present study tested the general hypothesis that behavioral attributes most predictive of the incidence of coronary heart disease (CHD) in epidemiological research would also be most predictive of sympathetic autonomic nervous system (ANS) arousal in response to performance challenges. Subjects (n = 50) were challenged to respond rapidly and accurately on three tasks involving either perceptual-motor or cognitive skills, while the experimenter monitored blood pressure, heart rate, and galvanic skin potential. The hypothesis was generally confirmed in that (1) type A subjects showed significantly greater cardiovascular changes indicative of sympathetic ANS arousal than type B subjects, (2) the Rosenman and Friedman structured interview was a better predictor of this arousal than the Jenkins Activity Survey, as is the case in CHD, and (3) the stylistic and behavioral components of the type A pattern (as defined by the structured interview) which are most predictive of CHD were also found to be the best predictors of challenge-induced sympathetic ANS arousal. The implications of these results for refinements in the definition, assessment, and modification of coronary-prone behavior are discussed.
