一種新型更加精確的影象檢查被開發用于檢查冠狀動脈心臟病（CAD），能夠預測心臟病發作的危險，而且在床邊即可完成。

使用實時心肌對比超聲心動圖檢查(RTMCE)，臨床醫生現在能夠迅速有效的檢查冠心病。Nebraska大學醫療中心的研究人員在158例胸痛和疑似急性冠狀綜合征患者中使用RIMCE進行了多巴酚丁胺應激超聲心動圖掃描。他們發現：灌注成像掃描比多巴酚丁胺應激超聲心動圖掃描時候的心腔壁運動分析更好地檢查CAD，并能夠預測患者預后。

2005年7月期的《超聲心動圖檢查》期刊報道了這項研究結果，提示使用這種非侵入性技術能夠確定無法解釋原因胸痛患者的預后，患者能夠得到更加合適的治療并延長生存期。
 
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.
