A total of 100 patients were studied for the diastolic blood pressure response to treadmill exercise testing. No change in the diastolic pressure or lowering of the pressure was considered normal response. Seventy four patients had normal and 26 patients had abnormal diastolic blood pressure response. Out of these, 40 patients underwent coronary angiography. Fifty five percent of the patients with normal diastolic pressure response had normal coronaries compared to 20% with abnormal response (p < 0.03). Fifteen percent with normal response had triple vessel disease or left main coronary artery disease whereas forty percent with an abnormal response had significant disease (p < 0.03). Exercise induced ST segment depression was almost equal in both groups. Hence we can conclude that abnormal diastolic pressure response to treadmill exercise testing is a fairly good indicator of coronary artery disease irrespective of ST segment changes.
共有100名患者接受了平板运动试验时舒张压反应的研究。舒张压无变化或舒张压降低被视为正常反应。74名患者舒张压反应正常，26名患者舒张压反应异常。其中，40名患者接受了冠状动脉造影。舒张压反应正常的患者中55%冠状动脉正常，而反应异常的患者中这一比例为20%（p<0.03）。反应正常的患者中有15%患有三支血管病变或左主干冠状动脉疾病，而反应异常的患者中有40%患有严重疾病（p<0.03）。两组运动诱发的ST段压低情况几乎相同。因此我们可以得出结论，平板运动试验时舒张压反应异常是冠状动脉疾病的一个相当好的指标，与ST段变化无关。
