活动平板运动试验收缩压恢复比对冠心病的诊断价值

Diagnostic Value of the Ratio of Systolic Blood Pressure in Detecting Coronary Artery Disease

目的 探讨活动平板运动试验中收缩压恢复比 (rSBP)对冠心病的诊断价值。方法 选择 198例患者进行活动平板运动试验 ,与冠状动脉造影结果作对照。结果 rSBP >0 .91诊断冠心病的敏感度、特异度、诊断符合度分别为 5 3.6 %、83.7%、6 6 .7% ,而传统指标分别为 91.1%、5 5 .8%、75 .8% ;rSBP >0 .91在冠状动脉单支、双支和多支 3组病变中的诊断特异度均高于同组传统指标的诊断特异度 (P <0 .0 5 )。结论 运动试验中rSBP异常可预测冠状动脉疾病及其病变严重程度。

Objective To investigate the value of the ratio of systolic blood pressure (rSBP) on treadmill exercise test in diagnosing coronary artery disease.Methods 198 patients underwent treadmill exercise test and the data were analyzed and compared with the results of coronary angiography.Results The sensitivity,specificity and accuracy of the ratio of systolic blood pressure were 53.6%,83.7% and 66.7% respectively,while those of traditional index were 91.1%,55.8% and 75.8% respectively.The specificity of rSBP>0.91 in diagnosing single vessel disease,double and multi-vessel disease was higher than that of traditional index,(P<0.05).Conclusion The ratio of systolic blood pressure in exercise test can predict coronary artery disease and its severity.
