Several non-invasive studies are currently utilized for the identification of coronary artery disease  (i.e. coronary CTA, intravascular ultrasound- IVUS, etc.)
几项非侵入性的措施目前已经用于识别冠状动脉性疾病（例如冠状动脉CT成像，血管内超声等）。
Few studies have quantified which of those with CAD (i.e. coronary plaques) are considered high-risk or unstable plaques
很少有研究对高风险或者不稳定的斑块通过这些措施进行量化。
A recent study utilizing IVUS looked at autopsies over a 2 year-period comparing near-infrared detection of high-risk plaques and cardiovascular related deaths
最近一项为期两年的研究通过血管内超声在尸体中寻找高风险的斑块以及与心血管相关的死亡并与近红外线进行比较。
IVUS findings associated with CAD are classified into 3 categories: echo-attenuation, echolucent zone, and spotty calcification
血管内超声发现的冠状动脉疾病相关的病变可以分为3类：回声减弱区，无回声区以及点状钙化区。
Echo-attenuated plaques, especially superficial echo-attenuation, was found to be a significant and reliable finding suggestive of vulnerable plaques and future cardiovascular death 
回声减弱的斑块尤其是浅表的回声减弱被认为是提示不稳定斑块以及将来心血管相关死亡的一项重要可靠的指标。
