There are few studies on the behavior of the diastolic blood pressure during the stress test. The purpose of this report is to present a simple, noninvasive technique of measuring the mean diastolic arterial blood pressure at rest, during maximal exercise testing and in the first minute of recovery (X delta DAP). We studied 132 patients with exercise testing (E/T) and coronariography (C). Of these, 116 had coronary artery disease and 16 did not. The following data were analyzed: Age (A) X delta DAP, X2, p value, sensitivity, specificity, positive predictive value (PV+), and negative predictive value (PV-). As we analyzed our patients with coronary arterial disease, we found that in 75% of the cases, the X delta DAP increased more than 15 mmHg, immediately after maximal effort, and 86% of these cases had poor myocardial contratility by angiocardiogram. We conclude that the increase of X delta DAP has a significant value in a ischemic heart disease.
关于应激试验期间舒张压行为的研究较少。本报告的目的是介绍一种简单、无创的技术，用于测量静息时、最大运动试验期间以及恢复第一分钟的平均舒张动脉血压（X delta DAP）。我们研究了132例进行运动试验（E/T）和冠状动脉造影（C）的患者。其中，116例患有冠状动脉疾病，16例没有。分析了以下数据：年龄（A）、X delta DAP、X2、p值、敏感性、特异性、阳性预测值（PV+）和阴性预测值（PV-）。当我们分析患有冠状动脉疾病的患者时，我们发现，在75%的病例中，最大努力后立即出现X delta DAP升高超过15 mmHg，并且这些病例中有86%通过心血管造影显示心肌收缩力较差。我们得出结论，X delta DAP的升高在缺血性心脏病中具有重要价值。
