Since its inception in 2008, JACC: Cardiovascular Imaging (iJACC) has served as an important publication for all contemporary aspects of cardiovascular imaging. Understanding the dissemination trends in cardiovascular imaging has traditionally been evaluated through citations that assess interest in the research community. Recently, social media, alternative metrics (Altmetrics), and other modern metrics have enabled a more broader understanding of the interests of clinical readership. Through the prism of Altmetrics, this review discusses the most impactful studies across the spectrum of cardiovascular imaging within and outside of iJACC during a 3-year period (2017 to 2019). The top 100 Altmetrics iJACC articles in this timeframe, included articles with the highest impact with the combination of high Altmetrics (median: 66; interquartile range [IQR]: 56 to 108), high citations (median: 26; IQR: 17 to 34), and high downloads (median: 9,626; IQR: 5,770 to 11,435). This review aims to provide a framework to understand how to incorporate these metrics for a modern approach to dissemination of knowledge in the field of cardiovascular imaging.
