The purpose of this study was to determine the prognostic importance of positive exercise treadmill test (ETT) in predicting coronary artery disease (CAD) among asymptomatic population based on coronary angiographic findings.
The comparative study was conducted on a sample of over 60-year-old asymptomatic and symptomatic patients referred to our clinics for screening and clinical reasons between September 2006 and September 2007. All subjects with a positive ETT provided information about their cardiovascular risk factors through a validated questionnaire. The relationship between ETT performance and the CAD risk factors with coronary angiography were studied and compared between the two groups.
Seven hundred thirty one symptomatic and 160 asymptomatic individuals were enrolled in the study. In the symptomatic group, gender, blood pressure and diabetes were significantly related with the angiographic findings, while blood pressure failed to show such a relation in the asymptomatic group.
There is an association between positive ETT and the presence of CAD among asymptomatic elderly men but also women with diabetes or high blood pressure.
本研究旨在基于冠状动脉造影结果，确定运动平板试验（ETT）阳性在无症状人群中预测冠状动脉疾病（CAD）的预后重要性。
本对比研究对2006年9月至2007年9月间因筛查和临床原因转诊至我们诊所的60岁以上无症状和有症状患者样本进行。所有ETT阳性的受试者通过一份经过验证的问卷提供了有关其心血管危险因素的信息。研究了ETT表现与冠状动脉造影的CAD危险因素之间的关系，并在两组之间进行了比较。
731名有症状个体和160名无症状个体纳入研究。在有症状组中，性别、血压和糖尿病与造影结果显著相关，而在无症状组中血压未显示出这种关系。
在无症状老年男性以及患有糖尿病或高血压的女性中，ETT阳性与CAD的存在之间存在关联。
