However, in the years after surgery, the veins commonly narrow and may block leading to angina, heart attacks and heart failure. Our team has developed a new approach to prevent vein graft failure.\u201d<\/p>\n<p>Prof Dawson said: \u201cBy using gene therapy during bypass surgery, we aim to improve the durability of vein grafts and reduce the risk of complications.<\/p>\n<p>\u201cOur ultimate goal is to help patients not only live longer but enjoy a better quality of life after surgery.\u201d<\/p>\n<p>Professor James Leiper, director of research at the British Heart Foundation, said: \u201cThis pioneering study is an inspiring reminder of how far gene therapy, which was once a distant scientific ambition, has come.<\/p>\n<p>\u201cResearch funding from the BHF over many years laid the groundwork for this study, generating the knowledge needed to move this research out of the lab and towards the clinic.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"John MacDonald, 73, suffered a heart attack at his home in Stornoway on the Isle of Lewis in&hellip;\n","protected":false},"author":2,"featured_media":681766,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7826],"tags":[748,918,4884,712,16,15],"class_list":{"0":"post-681765","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-glasgow","8":"tag-britain","9":"tag-glasgow","10":"tag-great-britain","11":"tag-scotland","12":"tag-uk","13":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115858444768945608","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/681765","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=681765"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/681765\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/681766"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=681765"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=681765"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=681765"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
