英国爱丁堡大学等机构的研究人员11月11日在英国医学期刊《柳叶刀》网站上报告说，他们发现心脏动脉中的脂肪斑块破裂形成血栓、堵塞血管，是造成心肌梗塞的主要原因，如能尽早发现这些斑块，就有助于预防心梗发作。在新研究中，科研人员将两种放射性示踪剂注入一些心脏病患者的血液，然后利用正电子发射计算机断层扫描技术，显示其心血管内脂肪斑块的高清图像，以此判断患者发生心梗的风险。

这一新技术可准确发现心血管内的脂肪斑块并判断其破裂风险。据报告，该试验共有40名心脏病患者参与，用这一新技术判断心梗的准确率高达约93％。研究者认为，还有必要进行更大规模的临床试验以证实其有效性。

领导这项研究的爱丁堡大学心脏病专家马克·德维克说，虽然并非所有脂肪斑块都会引发心肌梗塞，但尽早发现这些斑块并找出其中破裂风险较高者，有助于医生判断患者的心梗风险，从而采取适当的预防措施。
