The Type A behaviour pattern has been associated with the onset of myocardial infarction (MI). So too, though independently, has the presence of stressful life-events in the period preceding illness. The present paper examines the notion that persons characterized by the Type A behaviour pattern organize life-styles in such a way as to increase the probability of encountering stressful life-events. Significant correlations were indeed found between a measure of Type A behaviour and both reported frequency of life-events and estimates of the emotional impact of these, for a sample of 120 survivors of MI. While such retrospective data do not provide casual evidence that Type A behaviour influences MI by way of stressful life-events, they point the way to a future prospective test of this hypothesis.
A型行为模式与心肌梗死（MI）的发病有关。同样，在患病前的一段时间里，应激性生活事件的存在也与心肌梗死有关，尽管二者是独立关联的。本文探讨了这样一种观点，即具有A型行为模式的人以某种方式组织生活方式，从而增加遭遇应激性生活事件的可能性。对于120名心肌梗死幸存者的样本，确实发现A型行为的一种测量方式与所报告的生活事件频率以及这些事件的情感影响评估之间存在显著相关性。虽然这些回顾性数据并不能提供A型行为通过应激性生活事件影响心肌梗死的因果证据，但它们为该假设的未来前瞻性检验指明了方向。
