Bypass, stents equally safe five years on: study
  
研究显示：心脏搭桥手术与支架植入术的5年预后情况无差异

WASHINGTON (Reuters) –
Patients who got heart bypass surgery and those who got their blocked arteries propped open with stents fared equally well five years after their procedures, South Korean doctors reported on Wednesday.

The study of more than 2,200 patients showed no difference in death, heart attack or stroke between the two groups, Dr. Duk-Woo Park of Ulsan College of Medicine in Seoul and colleagues reported.

韩国医生5月5日报道，接受心脏搭桥手术的患者和放置支架撑开阻塞动脉的患者术后5年预后相同。

一项纳入了超过2200例患者的研究显示，搭桥手术组和支架组之间患者死亡率、心脏病发作或中风无差异，汉城蔚山医学院Duk-Woo Park和同事报告说。

The patients all had a serious heart blockage called unprotected left main coronary artery stenosis, which doctors agree needs treatment.

But heart surgeons have disagreed about whether stretching the artery open and inserting a wire mesh tube called a stent is as effective as more traditional bypass surgery.

受试者均有严重心脏血管阻塞，即所谓的无保护左主干冠状动脉狭窄，医生以致认为需要治疗。

但是，对于支架置入术是否与传统心脏搭桥手术一样有效，心脏外科医生的观点不一致。

"There was no significant difference in the risks of death," the researchers wrote in the journal of the American College of Cardiology.

The European Society of Cardiology's spokesman William Wijns said the study showed that angioplasty with a stent should be considered as an option for patients who do not want bypasses.

“搭桥手术组和支架组之间死亡风险比较差异无明显统计学意义，”研究人员在《American College of Cardiology》上写道。

欧洲心脏病学学会发言人William Wijns说，研究显示，支架置入血管成形术应作为不愿意行搭桥手术患者的一项治疗选择。
