A bit late google. Depending on what you mean by heart disease (it is a very broad category), but if you mean heart disease caused by high cholesterol then it has already been cured and available as a license monoclonal - Evolocumab [1]. We know that knocking the protein it targets (PCSK9) is without side-effects in humans [2]. It will take a few years before everyone is on it, but basically all the science is done.<p>Edit. Personally I like the vaccine approach [3] as it could be low cost and avoid the need for monthly injections, but I doubt we will ever see this taken through to market. If google wanted to do some good then spend their money sponsoring a human trial of the PCSK9 vaccine.<p>1. <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Evolocumab" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Evolocumab</a><p>2. <a href="http:&#x2F;&#x2F;www.nature.com&#x2F;news&#x2F;genetics-a-gene-of-rare-effect-1.12773" rel="nofollow">http:&#x2F;&#x2F;www.nature.com&#x2F;news&#x2F;genetics-a-gene-of-rare-effect-1....</a><p>3. <a href="http:&#x2F;&#x2F;www.sciencedirect.com&#x2F;science&#x2F;article&#x2F;pii&#x2F;S0264410X15013201" rel="nofollow">http:&#x2F;&#x2F;www.sciencedirect.com&#x2F;science&#x2F;article&#x2F;pii&#x2F;S0264410X15...</a>
