目的探讨运动试验中收缩压恢复比对冠心病的诊断价值。方法对苏州大学附属第一医院2003—2005年收治的88例冠状动脉造影的患者行平板运动试验,分析运动停止后3min收缩压恢复比与冠状动脉造影的相关性。结果3min收缩压恢复比对冠心病诊断的敏感性、特异性、准确性、阳性预测值分别为:55·6%、82·0%、73·9%、57·7%,与心电图ST段改变的标准相比,差异有显著性意义(P<0·05)。结论运动试验收缩压恢复比对冠心病的诊断,在特异性、准确性、阳性预测值等方面要明显优于心电图ST段压低标准。
Objective To investigate the diagnostic value of systolic pressure recovery ratio in coronary heart disease during exercise test. Methods Eighty-eight patients undergoing coronary angiography were enrolled in the First Affiliated Hospital of Soochow University during 2003-2005. The treadmill exercise test was performed to analyze the relationship between systolic blood pressure recovery ratio and coronary angiography at 3 minutes after the exercise was stopped. Results The sensitivity, specificity, accuracy and positive predictive value of systolic pressure recovery at 3 min were 55.6%, 82.0%, 73.9% and 57.7% The difference was statistically significant (P <0.05). Conclusions The recovery rate of exercise test systolic pressure in the diagnosis of coronary heart disease in the specificity, accuracy, positive predictive value should be significantly better than the ST segment depression standard ECG.
