摘要
目的探讨如何提高平板运动试验(TET)的准确性。方法于1995~1997年10月给147名拟诊心绞痛或冠心病住院者在冠脉造影(CAG)前作TET,采取两项措施以提高TET的正确率。(1)对每例患者在检查前均详询胸痛特征,将其分为缺血型(ICP)或非缺血型(NICP)两类,与TET一并分析;(2)综合分析胸痛、ST段压低及SBP比等参数,本文以两项以上异常定为TET阳性标准。结果(1)胸痛为ICP型、TET阳性诊断冠心病的敏感性达95%,而NICP型胸痛者TET若为阴性,则98%冠脉正常;(2)以本文标准判断TET阳性或阴性,敏感性为89%,特异性达95%,均高于一般资料。结论分析TET结果,应结合病史,尤其重视胸痛的特征,尚应全面分析反映心肌缺血的各方面表现。
Objective To research how to improve the accuracy of treadmill exercise testing.Methods TET was performed before coronary angiography (CAG) in 147 subjects admitted into hospital because of suspicion of angina or coronary artery disease(CAD),then(1) every subject was inquired about his symptoms and physically examined in detail before the testing.Chest pain was divided into ischemic (ICP)and non-ischemic(NICP) two patterns.(2)informations got from TET,like angina,ST segment depression,and SBP ratio,were analyzed comprehensively.Results (1)When the patients showed chest pain of ICP pattern and positive TET results ,the sensitivity of TET would be 95%,for patients with NICP chest pain,the negative result of TET means that their cornary arteries will be normal with the accurate possibility of 98%.(2)By the above new criteria of TET,the sensitivity and specificity of TET were 89% and 95% respectively,both higher than those in the literature.Conclusion We could report our TET more accurately if we know the symptoms in detail and consider different parameters in combination.
