Two groups of patients with only marginally abnormal systolic blood pressure gradients from arm to ankle were studied. Group A consisted of 24 patients, who had arteriography performed for unilateral symptoms. In the non-symptomatic limbs a significant correlation was found between the severity of obliterations and the arm to ankle blood pressure gradients, which in all cases was less than 35 mmHg. In Group B consisting of 55 patients suspected of arterial obliterative disease the arm to ankle pressure gradient was measured at rest and after 2 min. of leg exercise. The diagnostic correctness of the two procedures were analysed by the direct method for evaluation of diagnostic tests using the clinical diagnosis as final diagnostic criterion. The maximal diagnostic correctness was 85 % for the gradient at rest using values between 20 and 25 mmHg as criterion for arterial obliterative disease. It equaled the maximal diagnostic correctness of 87 % of the gradient after exercise using values between 45 and 55 mmHg as criterion.
对两组臂踝收缩压梯度仅略有异常的患者进行了研究。A组由24例患者组成，这些患者因单侧症状接受了动脉造影。在无症状肢体中，发现闭塞严重程度与臂踝血压梯度之间存在显著相关性，在所有病例中该梯度均小于35 mmHg。B组由55例疑似动脉闭塞性疾病的患者组成，在静息状态和腿部运动2分钟后测量臂踝压力梯度。以临床诊断作为最终诊断标准，采用诊断试验评估的直接方法分析了这两种检查方法的诊断正确性。以20至25 mmHg作为动脉闭塞性疾病的标准，静息时梯度的最大诊断正确性为85%。这与运动后梯度以45至55 mmHg作为标准时的最大诊断正确性87%相当。
