心肌梗死全球統(tǒng)一定義與影像學(xué)診斷-預(yù)覽頁(yè)
【正文】 ramagic contrast agents can be used to assess myocardial perfusion and the increase in extracellular space associated with the fibrosis of chronic infarction. The former is not yet fully validated in clinical practice, but the latter is well validated and can play an important role in the detection of infarction. XRay Computed Tomography ? Infarcted myocardium is initially visible to CT as a focal area of decreased LV enhancement, but later imaging shows hyperenhancement as with late gadolinium imaging by MRI. ? This finding is clinically relevant because contrast enhanced CT may be performed for suspected embolism and aortic dissection, conditions with clinical features that overlap with those of acute myocardial infarction. 關(guān)鍵要點(diǎn) ?心電圖著重急性心肌缺血和先前（陳舊性）心肌梗死標(biāo)準(zhǔn) ?生物標(biāo)志物明確強(qiáng)調(diào)首推肌鈣蛋白，CKMB是次選，不被推薦 ?影像技術(shù)的發(fā)展使其在心肌梗死的診斷和分型中有一席之地 。心肌梗死全球統(tǒng)一定義與影像學(xué)診斷 何作祥 中國(guó)醫(yī)學(xué)科學(xué)院阜外心血管病醫(yī)院 Thygesen, K. et al.
