心脏造影手术和心脏支架的选择_Keon和Aiden

中年人的一地鸡毛啊，上有老，下有小。
妈妈下周一心脏造影手术，如果情况不好，有可能当场就做支架。我们现在面临的选择是：Bare Metel Stent（普通金属支架）和Drug Coated Stent （药物涂层支架）。 我不知道各有什么好坏。
护士说术后如果装了支架，要吃一种非常贵的药防止小血栓堵住支架，没保险的话，大概药费3-5百美金一个月。普通金属支架要吃3个月，药物涂层支架至少要吃一年。所以她现在给我们建议用普通金属支架
网上查了Harvard Medical School 研究说
Stents are tiny wire cages that can fit inside an artery. They wereinvented to prop open heart arteries after angioplasty cleared themof clogs. The first stents were made of bare metal. The drug-coatedversions release medication to stop restenosis, a regrowth of cellsthat can create a new blockage. Soon after drug-coated stents hitthe market, doctors began seeing heart attacks and sudden deathscaused by clots forming inside the devices.Researchers found thatclotting problems were twice as likely to happen with drug-coatedstents as with bare-metal ones. However, a longer-term analysisshowed no significant difference three years after surgery.
Which stent is right for you? The Harvard Heart Letter suggeststhat a d

rug-coated stent might be a good choice if the anatomy of theaffected artery makes it prone to restenosis; if you aren’tplanning any surgery in the next year; and if you're good abouttaking medications. (People with drug-coated stents need to takemedicine to prevent clotting for a year or more.)A bare-metal stentmight be better if you might need surgery soon or if you can’tafford the medications.
每月药3，5百费这个我可以忍受，但是Harvard医学院不是又说，有药物涂层的支架6个月后引起的心肌梗塞及死亡率大于普通金属的嘛，所以要吃一年以上的这个抗凝血药。妈妈现在因为吃阿司匹林血液已经很稀了，平时不小心切破了手，云南白药都止不住。
网上咨询，有人说：
普通球囊, restenosis rate 30%
BMS, restenosis rate 10 to 20%
DES, less than couple of percent.
late stage thrombsis is a issue, but recent DES all have goodbiocompatibility
cypher is very bad, high inflamation, high metal to artery ratio,only thing is it's the first.
boston scientific Taxus is not good either, since drug it used iscyto-toxic , not cyto-static.
Metronic and Abbott stent all good, which used rapamycinderivative, which is cto-static, means, not that toxic tocells.
Bill clinton used Abbott DES, just FYI.
这个最后一句话很给力，如果克林顿总统都选择的是药物支架，我们还犹豫什么呢。于是打电话给护士要求改成
药物支架
星期一早上带妈妈7：30入院等待手术。星期天半夜后就禁食，连水也不能喝。 希望一切顺利
