平板运动试验与超声心动图负荷试验对青年冠心病诊断的价值

Diagnostic value of treadmill exercise test and echocardiography stress test for coronary heart disease of youth

目的:探讨平板运动试验与超声心动图负荷试验对青年冠心病的诊断价值。方法:回顾性分析符合入选标准的疑似冠心病青年患者63例,分析患者的临床资料,包括平板运动试验、超声心动图负荷试验结果。结果:与冠脉造影结果比较,平板运动试验与超声心动图负荷试验阳性检出率差异均无统计学意义(P>0.05)。平板运动试验与超声心动图负荷试验对青年冠心病的诊断具有较高的敏感性、特异性、准确性以及阳性、阴性预测值,超声心动图负荷试验诊断价值更优;两种试验的阳性检出率均随着冠脉病变程度的加重而增加(P<0.05)。结论:超声心动图负荷试验对青年冠心病患者具有较好的诊断效能。

Aim： To explore the diagnostic value of treadmill exercise test and echocardiography stress test for coronary heart disease（ CHD） of the youth. Methods： A total of 63 cases of young borderline CHD patients were subjected to analyze the clinical data including the results of treadmill test and ultrasonic cardiogram test. Results：Compared with the results of coronary angiography,the positive rate of treadmill exercise test or echocardiography stress test had no significant difference（ P〈0. 05）. Compared with treadmill exercise test,echocardiography stress test had higher sensitivity,specificity,accuracy,positive and negative predictive value in the diagnosis of young CHD. The positive rates of treadmill exercise test and echocardiography stress test increased with the degree of coronary artery disease（ P〈0. 05）. Conclusion：Echocardiography stress test is valuable for the diagnosis of young CHD.
