【摘要】：正目前,診斷冠狀動(dòng)脈功能性狹窄的"金標(biāo)準(zhǔn)"是血流儲(chǔ)備分?jǐn)?shù)(fractional flow reserve,FFR)。FFR由Pijls等~([1])于1993年率先提出,并將其定義為在存在狹窄病變的情況下,該冠脈所提供給心肌區(qū)域能獲得的最大血流量與同一區(qū)域在正常情況下所能獲得的最大血流量之比。FFR可以較好的評(píng)價(jià)冠脈功能性的狹窄~([1-3]),并且多個(gè)多中心實(shí)驗(yàn)證實(shí),FFR是改善冠心病患者預(yù)后并降低醫(yī)療花費(fèi)的惟一指標(biāo)~([4-7])。
[Abstract]:At present, the "gold standard" for the diagnosis of functional coronary artery stenosis is blood flow reserve fraction (fractional flow reserve,FFR). FFR was first proposed by Pijls et al. [1] in 1993 and defined as in the case of stenosis. The ratio of the maximum blood flow provided by the coronary artery to the maximum blood flow that can be obtained in the same area under normal conditions. FFR can better evaluate the coronary artery functional stenosis ([1 鈮，
