【摘要】 目的 :探讨运动中收缩压恢复比 ( SPRR)异常对冠心病 ( CHD)诊断的价值。方法 :对1 50例患者进行活动平板运动试验并与冠状动脉造影对照。结果 :SPRR异常诊断的敏感性、特异性及准确性分别为 62 .0 %、96.0 %及 73.3% ,而 ST段压低则分别为 72 .0 %、86.0 %及 76.6%。结论 :CHD患者运动后引起 SPRR异常反应可预测冠状动脉病变。更多还原

【Abstract】 Objective:To study the significance of systolic pressure recovery rate using treadmill exercise test in diagnosing coronary heart disease.Method:One hundred and fifty patients with coronary heart disease underwent treadmill test and the data were analysed and compared with the results of coronary angiography.Result:The sensitivity, specificity, and accuracy of abnormal systolic pressure recovery rate were 62.0%, 96.0%, and 73.3% respectively, but those of ST depression were 72.0%, 86.0% and 76.6% respectively.Conclusion:Cononary artery affection can be predicted by the change of systolic pressure recovery rate after exercise.更多还原
