免费医学论文英文版

方法有很多，我推荐一下比较实用的网站：1、science 2、Highwire 3、Pubmed输入你要检索的标题或关键词，点“search”搜索，大部分资源可以免费下载PDF版，还可以通过全文查看“full text”查看论文内容，如果你在Pubmed中检索到但是不提供免费下载的文章，你可以向文章的作者写Email或浏览作者的主页，但这种方法不一定有效，其实你也可以选择在网上发布求助，请别人帮助你，推荐一个比较专业的丁香园医学专业网站，你可以发起求助，如果你运气好的话很快就有人回复你的。PMID即为pubmed数据库为收录的每一篇文献给出相对应的唯一编号，如下在“Display Setting”选择“Abstract”在摘要下方的数字就是该文章的PMID

Objective To evaluate acute and long2term angiographic and clinical outcomes of longstent or multiple overlapped stents (length ≥ 20 mm) implantation for diffuse atherosclerosis lesions inoctogenarians. Methods Long stent or multiple overlapped stents implantation was performed on 111diffuse native coronary lesions ( Group O : 47 lesions in 44 octogenarians ; Group Y: 64 lesions in 58 patientsaged under 60) . Baseline demographic , lesion characteristic , angiographic and procedural details weresimilar in these 2 groups. Six2month clinical and angiographic follow2up was completed in all cases. In2hospital and long2term outcomes were evaluated. Results Procedure success was 100 %for both had in2hospital major adverse cardiac events (MACE) . There was no significant difference inangiographic binary restenosis ( ≥50 % diameter stenosis) rate between the groups at follow2up ( Group Ovs. Group Y, 1218 % vs1 1019 % at 32month , 2918 % vs. 2616 % at 62month , P > 0105) . The rates oftarget lesion revascularization and MACE at follow2up were less in Group Y, but it showed no statisticalsignificance (718 % vs. 1016 % and 816 % vs. 1114 % at 32month , 1516 % vs. 2314 % and 2017 % % at 62month , respectively , P > 0105) . Conclusions Long stent implantation for diffuse lesionsin octogenarians appears safe and feasible , with high procedural success and favorable long2term outcomes.

你可以去创新医学网上看看，而且还有翻译服务。

去PubMed检索，列表后面有fulltext提示，部分新发布的论文免费提供全文。旧刊全文收费不便宜，一篇几美金到20多美金不等。

这个简单啊。你可以到PubMed中下载。输入关键词，然后检索即可。
