哈爾濱醫(yī)科大學的科研人員應用多巴酚丁胺負荷心肌造影術,，評價心肌微循環(huán)損傷，預測冠脈搭橋患者的心肌活性和術后心功能恢復狀況,，取得良好臨床效果,。相關成果日前發(fā)表在《臨床超聲雜志》和《美國醫(yī)學科學》雜志上。
據介紹,，研究人員將臨床上看起來非常普通,、床邊即能應用的超生設備與心肌灌注造影結合起來，用于評價心肌活性和再血管化治療后心功能恢復狀況及臨床療效,，而目前國內很少嘗試用負荷心肌造影來研究收縮功能障礙心肌的微循環(huán)血流量變化,。其創(chuàng)新之處在于，通過上述技術手段估測收縮功能障礙心肌負荷后心肌血流量的變化,，進而預測左室局部功能的恢復情況,。
臨床實踐表明,，這一技術可對橋血管通暢性予以準確評估，改善對搭橋術預后的評價,。其可靠性,、方便性以及檢測費用的低廉性也在逐步顯現。（生物谷 Bioon.com）

Left anterior descending artery occlusion secondary to blunt chest trauma diagnosed by comprehensive echocardiography and coronary angiography

Blunt chest trauma can cause serious complications, but coronary artery occlusion is rare. In a 19-year-old man, 40 days after a motorcycle accident, comprehensive echocardiography detected left anterior descending artery occlusion and left ventricular dysfunction, which was confirmed by coronary angiography and ventriculography. Echocardiography was also able to confirm restored left anterior descending artery flow and improved left ventricular function after coronary artery bypass grafting.
