目的 探讨平板运动试验恢复期收缩压异常升高对冠心病诊断的临床意义和影响.方法 对192例平板运动试验阳性者作冠状动脉造影.根据冠状动脉造影结果以及运动后收缩压有无异常升高进行分组,以运动后(恢复期)6min内,收缩压后期比前期升高≥10 mmHg(1 mmHg=0.133 Kpa)为收缩压异常升高的阳性判断标准.结果 运动后收缩压异常升高和ST段压低两者联用对诊断冠心病的敏感性、特异性、准确性均高于单纯性ST段压低标准.两指标(收缩压异常升高和ST段压低)联用可显著提高诊断冠心病的敏感性和阳性率.结论 平板运动试验恢复期收缩压异常升高可作为诊断冠心病的重要参考指标.%Objective To explore the clinical significance and effect of abnormal elevation of systolic blood pressure during the recovery stage of treadmill exercise testing on the diagnosis of coronary heart disease.Methods Coronary artery angiography was performed on 192 patients positive with treadmill exercise testing.According to the coronary angiography results and the presence or absence of abnormal elevation of systolic pressure after exercise.The standard for positive result was the late systolic pressure frequency increased 10 mm Hg or more ( 1 mm Hg =0.133 Kpa ) than the early systolic pressure after exercise.Results The sensitivity,specificity,and accuracy of abnormal elevation of systolic pressure combined with ST-segment depression were higher than those of ST-segment depression alone.Detection of the two indexes could markedly increase the sensitivity and positive rate of the diagnosis of coronary heart disease.Conclusions Abnormal elevation of systolic blood pressure during the recovery stage of treadmill exercise testing recovery can be used as an important indicator for the diagnosis of coronary heart disease.
