Social media for cardiovascular journals: State of the art review

In cardiovascular (CV) medicine, the use of social media (SoMe) has increased the dissemination of scientific knowledge, including the sharing of scientific journal articles. With the rapid growth of online methods for communicating scientific research, the critical question is whether online attention correlates with citations in academic journal articles. Traditionally, the performance of a scientific journal article has been determined by the number of times it has been cited. The impact factor and the number of citations in peer-reviewed journals are widely accepted measures of scientific impact. Social media platforms such as Twitter (Twitter.com) enable the development of novel article- or journal-level metrics for assessing effect and influence. Indeed, "alternative metrics" for journal article impact have been proposed, with the most frequently used being the Altmetric Attention Score (AAS; Altmetric.com). The relationship between these new metrics and established indicators such as citations has not been thoroughly investigated. We summarize numerous studies investigating associations between social media posts about journal articles and journal article citations. We then describe our own journal's social media strategy in light of these findings.
