Bicycle exercise stress tests of 39 patients with coronary heart disease are compared to those of 33 healthy persons. The difference in enddiastolic pulmonary artery pressure (PAEDP) of the patients compared to the healthy is low at rest (PAEDPhec healthy = 8.49 +/- 2.80, PAEDPCHD = 10.51 +/- 5.09, p = 0.05). Stress testing (50 Watts) brings significant differences of the average enddiastolic pressures (PAEDP healthy = 12.76 +/- 3.61, PAEDPCHD = 19.38 +/- 7.96, p = 0.001). More important than this (already well known difference) is the wide divergence of results within the group of patients with CHD. For this reason this type of investigation seems to be a good "screening method" regarding selection for coronary arteriography. The reason for the pathological rise of PAEDP can be found in a decrease of compliance due to ischaemia ("coronary factor"), or in exercise induced temporary heart failure ("myocardial factor"), or both.
对39例冠心病患者的自行车运动压力测试结果与33例健康人的测试结果进行了比较。与健康人相比，患者静息时舒张末期肺动脉压（PAEDP）的差异较小（健康人PAEDP = 8.49±2.80，冠心病患者PAEDP = 10.51±5.09，p = 0.05）。压力测试（50瓦）使平均舒张末期压力出现显著差异（健康人PAEDP = 12.76±3.61，冠心病患者PAEDP = 19.38±7.96，p = 0.001）。比这一（早已为人所知的差异）更重要的是，冠心病患者组内结果差异很大。因此，就冠状动脉造影的选择而言，这类检查似乎是一种很好的“筛查方法”。PAEDP病理性升高的原因可能是缺血导致顺应性降低（“冠状动脉因素”），或运动诱发的暂时性心力衰竭（“心肌因素”），或两者皆有。
