Five prospective cohort studies were compared in order to evaluate the relationship between type A personality (aggressive behavior) and coronary heart disease (CHD). The Western Collaborative Group Study (WCGS) demonstrated increased risk for CHD in males with type A personality. A follow-up study revealed a greater incidence of second myocardial infarction. The Framingham study showed higher rates of CHD in type A men and women. Two studies, MRFIT and a third evaluation of the WCGS, revealed no relationship between type A personality and CHD and mortality due to CHD. Because the studies disagree in the relationship between type A personality and CHD, it is impossible to conclude that type A personality is a risk for CHD.
为了评估A型人格（攻击行为）与冠心病（CHD）之间的关系，对五项前瞻性队列研究进行了比较。西方协作组研究（WCGS）表明，具有A型人格的男性患冠心病的风险增加。一项随访研究显示，第二次心肌梗死的发生率更高。弗明汉姆研究表明，A型男性和女性患冠心病的比例更高。两项研究，即多重危险因素干预试验（MRFIT）和对WCGS的第三次评估，表明A型人格与冠心病以及冠心病导致的死亡率之间没有关系。由于这些研究在A型人格与冠心病的关系上存在分歧，因此无法得出A型人格是冠心病危险因素的结论。
