动态心电图联合运动平板试验诊断冠心病的临床价值

目的：探讨动态心电图单独与联合运动平板试验诊断冠心病的临床价值。方法：选取175例疑似冠心病患者,入院后2周内完成Holter和TET检查,间隔2周以上行冠脉造影检查,比较3种方法阳性率以及单用Holter或TET与联合检测对血管病变的敏感性。结果：单用两种方法对各种数量冠脉病变检出敏感性之间差异无统计学意义（P〉0.05）,联合检测特异性为100.0%,阳性预测值为94.4%。结论：两者联合检测冠心病能做到无创、简单、安全,在保证诊断敏感性的前提下,减少了患者医疗费用。

The clinical value of holter combiened with exercise treadmill test in the diagnosis of coronary artery disease

Objective： To evaluate the clinical value of holter combiened with exercise treadmill test in the diagnosis of coronary artery disease.Methods： 175 patients with holter within 2 weeks after admission and TET check interval of 2 weeks or more coronary angiography,the positive rate of 3 methods were compared with holter or combined with TET sensitivity of detection of vascular disease.Results： Detection sensitivity of various number of coronary lesions had no significant difference between the two methods（P0.05）,joint detection specificity was 100.0%,positive predictive value was 94.4%.Conclusion： The combination of the two non-invasive detection of coronary artery disease is an simple,safe,guaranteed method of diagnostic,it can reduce patient care costs.
