2. Mixing(混合) technology (intervention operation simultaneously bypass surgery),
3. gene therapy vascular endothelial growth factor etc.
these methods have reduce trauma (创伤)and complications (并发症) role。
After the procedure
Intensive Care Unit （ICU） Heart monitor(监护仪器 ) Pacing wire to control heart rate Keep breathing

Surgical disadvantage
Therefore, looking for more advanced technology to solve these problems is necessary.
new technology
1. minimally invasive (微创) coronary artery bypass surgery,
IV line（静脉通道 ） Oral or IV sedative（镇静 ） General anesthesia（全身麻醉 ） Breathing tube（呼吸管 ） Catheter placed in bladder（导尿 ）
Surgical procedure
Open the skin, muscle, sternum（胸骨） and expose the heart in turn.
Coronary Artery Bypass Graft
(CABG)
Members:宋汴京 杨冠佼 张鸿雁 赵春梅 赵遍 景霆
Coronary heart disease（冠心病） known as “the first killer to human health”.
Its incidence（发病率）is increasing year by year and showing younger trend.
coronary arteries (冠状动脉)
The disease affects our normal work and life seriously, but it is not easy to cure radically by medical treatment.
Before the procedure
Coronary artery bypass graft curative effect is distinct, also have a few complications (并发症) .
Such as lungs and wound infection, brain and kidney damaine to instead of heart extracorporeal（体外） circulation.
intercept a period of great saphenous vein（大隐静脉）.
establish bypass cycle.
Among them, the vascular endothelial growth factor have (血管内皮生长因子) establish collateral circulation(侧支循环) role.
