冠脉狭窄经导管介入后最初6个月,有30%～50％发生再狭窄。本研究旨在确定多巴酚丁胺负荷超声心动图(DSUCG)检出经皮腔内冠脉成形术(PTCA)后再狭窄的用处。对象和方法 103例(28～78岁)PTCA后6个月经冠脉造影和DSUCG进行比较。103例中31例
Restenosis occurred in 30% to 50% of the first 6 months after catheterization of coronary stenosis. This study was designed to determine the usefulness of dobutamine stress echocardiography (DSUCG) for detecting restenosis after percutaneous transluminal coronary angioplasty (PTCA). Subjects and Methods 103 patients (28-78 years) after PTCA 6-month coronary angiography and DSUCG were compared. 31 cases in 103 cases
