The coronary arteries of 288 aircrew (135 military aircrew, 53 professional pilots, and 100 private pilots) killed in 210 aircraft accidents were examined to assess the prevalence of coronary artery disease (CAD). Included in the study were 132 controls of apparently healthy British males aged 18-62 years killed accidentally. The prevalence of significant CAD was found to be 17% in military aircrew with a mean age of 29.1 years, 24.5% in professional pilots with a mean age of 39.7 years and 22% in private pilots with a mean age of 37.2 years. In the control group, the prevalence was 18.2% with a mean age of 29.9 years. There was no evidence of a significant difference in CAD prevalence in the four groups (p greater than 0.1). The difficulties in grading CAD and comparing results with other published series is discussed. When taking the author's military aircrew and professional pilots as one group, so that the prevalence can be compared with previous UK series, it is found that prevalence of significant CAD (19%) is not significantly different from the prevalence reported two decades ago (p greater than 0.1). It is concluded that findings suggest that the prevalence of CAD is not declining in the United Kingdom.
对在210起飞机事故中丧生的288名机组人员（135名军事飞行员、53名职业飞行员和100名私人飞行员）的冠状动脉进行了检查，以评估冠状动脉疾病（CAD）的患病率。该研究纳入了132名年龄在18 - 62岁之间意外死亡的貌似健康的英国男性作为对照。结果发现，平均年龄为29.1岁的军事飞行员中，严重CAD的患病率为17%；平均年龄为39.7岁的职业飞行员中，患病率为24.5%；平均年龄为37.2岁的私人飞行员中，患病率为22%。在对照组中，平均年龄为29.9岁，患病率为18.2%。四组CAD患病率无显著差异（p大于0.1）。文中讨论了CAD分级以及与其他已发表系列结果比较的困难。将作者研究中的军事飞行员和职业飞行员作为一组，以便能与英国以前的系列进行患病率比较，结果发现严重CAD的患病率（19%）与二十年前报告的患病率无显著差异（p大于0.1）。研究得出结论，这些发现表明在英国CAD的患病率并未下降。
