多巴酚丁胺彩色动力技术超声心动图与心电图负荷试验对冠心病诊断的比较

Comparision of Dobutamine Stress Echocardiography By Color Kinesis and Dobutamine Stress Electrcardiogram Test For Detecting Coronary Artery Disease

本文对拟诊或可疑冠心病(CAD)者和正常人40例全部进行多巴酚丁胺彩色动力技术(CK)超声心动图负荷试验(D—CK)和多巴酚丁胺心电图负荷试验(D—ECG),然后再与冠脉造影结果进行对照.结果表明:D—CK和D—ECC诊断CAD的敏感性、特异性、准确性分别为100%和80.95%、83.33%和75%、93.94%和78.79%.应用D—CK能够提高对室壁缺血部位的检测,优于D—ECG.D—CK为CAD诊断提供了一种安全、可靠的方法.

In this studies, 40 subjects with and without CAD suspected underwent the dobutamine stress color kinetic e-chocardiography(D - CK) and dobutamine stress electrocardiogram test (D - ECG) .The results showed: Compared with coronary arteriography, the diagnostic sensitivity, specificity and accuracy were 100% & 80.95% , 83. 33% & 75%and 93.94% & 78.79% respectively for detecting CAD by D - CK and D - ECG. Detection for ischmia area of ventricular wall by D - CK was better than D - ECG.In the conclusion, D - CK is the safe.accurate and reliable method for diagnosing coronary artery disease and detecting myocardial ischemia.
