1、心肌梗死的药物/介入策略,时间就是心肌，就是生命,时间对再灌注抢救的意义,0-0.5 hrs预防梗死0.5 2 hrs 大量挽救心肌+IRA开通的益处2 6 hrs心肌挽救降低,IRA开通的益处 6 hrs基本不挽救心肌,但有IRA开通的益处,90年代中已证明溶栓治疗的益处与安慰剂对比,2003年，心梗治疗-溶栓与介入对比-We know,是否意味着都做PCI?PCI时间肯定要比直接注射药物长，不是所有医疗机构都具有PCI条件。所以一系列问题需要研究,溶栓与介入的比较,NRMI-2:死亡率与时间的关系,Door-to-Balloon Time(minutes),校正了的死亡率,P=0.01,P

2、=0.0007,P=0.0003,n=2,230,5,734,6,616,4,461,2,627,5,412,“拖”多久可以接受？,2004ACC/AHAAMI指南的选择的推荐,下列情形下溶栓更好到院很早（3h）介入可能延迟介入不可选 导管室没空 血管入路有困难 没有熟练的医生介入延迟(Door-balloon)-(Door-needle)1hMedical contact-balloon time1.5h,下列情形下介入更好熟练的队伍且有外科保障(Door-balloon)-(Door-needle)3h诊断STEMI有疑问,如果3小时之内到院，没有特别情况，两种方案均可,我们已经知道,PC

3、I优于溶栓但是PCI慢于溶栓，慢可用疗效弥补，但有个度这个“度”的把握很重要,北京的调查显示，D2B时间达标比例低,如何选择溶栓与介入？溶栓后还可以介入？,溶栓与PCI选择之考虑,至少有部分病人，溶栓可能优于PCIWho?When?Where?What?Which?,Sx Door Needle Balloon,策略的变化,2003 Greg Stone(Lancet):PPCI regardness of nearest cath suite 3 floors or 3 hrs away2007JACC ACCAHA guidelineLytic if anticipated PPCI is

4、 90min give lytic within 30min,选择依据1-起病长短,选择依据2-拖延时间起病早3h到院者PCI/溶栓的衡量,圆的尺寸=单独研究的样本大小.实 线=加权meta回归.,62 分钟,获益支持PCI,受损支持溶栓,PCI 每延迟10分钟，与溶栓间的死亡率的差异将减少1%Sx-B每延长30min，RR=1.08,选择依据2-拖延时间NRMI资料,192509例患者，645个中心,Circulation 2006；114：2019-25,114min是个坎但：所有病人一样吗？,选择依据3-患者本身风险DANAMI-2发现转运PCI有益于高危者,选择依据4年龄，梗死部位，就

5、诊时间,Circulation 2006；114：2019-25,直接PCI的可接受延搁时间取决于患者病情,Z=0.59X-0.033Y-0.0003W-1.3,Z=PPCI对TT的益处；X=本身死亡率；Y=PCI延误W=患者症状到就诊时间,越是高危，PPCI越经“拖”,直接PCI的可接受延搁时间取决于患者病情,50yM diabetic Pt,3h Ant STEMI hemodynamically stable;TRS=3;Mortality=4.4%D2B-D2N=43min,74-yM Pt,3hAnt STEMI hemodynamically unstableTRS=5;Morta
