美研究人员使用超声心动图检查心脏病

 
 
一种新型更加精确的影象检查被开发用于检查冠状动脉心脏病（CAD），能够预测心脏病发作的危险，而且在床边即可完成。

使用实时心肌对比超声心动图检查(RTMCE)，临床医生现在能够迅速有效的检查冠心病。Nebraska大学医疗中心的研究人员在158例胸痛和疑似急性冠状综合征患者中使用RIMCE进行了多巴酚丁胺应激超声心动图扫描。他们发现：灌注成像扫描比多巴酚丁胺应激超声心动图扫描时候的心腔壁运动分析更好地检查CAD，并能够预测患者预后。

2005年7月期的《超声心动图检查》期刊报道了这项研究结果，提示使用这种非侵入性技术能够确定无法解释原因胸痛患者的预后，患者能够得到更加合适的治疗并延长生存期。
 
Echocardiography Detects Heart Disease
 
A new, more accurate imaging modality has been developed to detect coronary heart disease (CAD) and predict the risk of heart attack, and it can be performed right at the bedside.

Utilizing real-time myocardial contrast echocardiography (RTMCE), a kind of ultrasound, clinicians are now able to quickly and effectively detect CAD. Researchers from the University of Nebraska Medical Center (Omaha, USA; www.unmc.edu) conducted dobutamine stress echocardiography scans in 158 patients presenting with chest pain and suspected acute coronary syndrome using the RTMCE technique. They discovered that perfusion imaging was better than wall motion analysis during dobutamine stress echo scanning for the detection of CAD and predicting patient outcome.

This study, which was published in the July 2005 issue of the journal Echocardiography, suggests that by using this noninvasive technique to determine patient outcome with unexplained chest pain, patients can then be put on the appropriate course of treatment for long-term survival.
