在100例连续的疑似心绞痛而作了冠脉造影的患者(22例女性,78例男性,平均年龄57岁),估价了应激超声心动图在冠心病常规诊断的价值。所进行运动包括自行车测力试验,还有经食道心房刺激(16例)、潘生丁(33例)和多巴酚丁胺(33例)输注等刺激运动试验。这些方法中至少有一种在91例患者获得了成功运用,而运动心电图只在78例取得成功(P<0.05)。应激超声心动图比运动心电图的敏感性(90%比78%)和特异性(90%比73%)为高。室壁运动的半定量检测能将功能不受影响的冠脉狭窄患者与单支或多支(冠脉)
In 100 consecutive patients with suspected angina who underwent coronary angiography (22 women, 78 men, mean age 57 years), the value of stress echocardiography in the routine diagnosis of coronary heart disease was evaluated. The exercises included bicycle force test, stimulation of transesophageal atrial stimulation (16 cases), dipyridamole (33 cases) and dobutamine (33 cases). At least one of these methods was successfully used in 91 patients, while exercise ECG achieved success in only 78 (P <0.05). Stress echocardiography was more sensitive (90% vs. 78%) and specificity (90% to 73%) than exercise ECG. Semi-quantitative detection of ventricular wall motion can function in patients with coronary artery stenosis and single or multiple (coronary)
