Peterson等人对1994～1997年参加美国心血管网络数据库的12家医院所用的经皮冠脉介入治疗(PCI)仪器的技术沿革和患者预后进行了分析,发现了无可否认的趋向。 (一)人们对粥样斑块切除术等几种导管的初期热情消失了。现在已很少应用,至少现在是这样。其中应用最多的有2种:斑块直切术和斑块环切术,从1994年两者的应用占PCI近25％已减至1997年的10％。 Peterson and colleagues analyzed the evolution and prognosis of percutaneous coronary intervention (PCI) equipment used in 12 hospitals participating in the US cardiovascular network database from 1994 to 1997 and found an undeniable tendency. (A) The initial enthusiasm for several catheters such as atherectomy disappeared. It’s rarely used now, at least for now. Among them, there are two types that are most widely used: plaque resection and plaque circumcision, which have been reduced from nearly 25% of PCI in 1994 to 10% in 1997.
