Circulation Research Thematic Synopses: The goal of Thematic Synopses is to provide our readers with a concise but comprehensive overview of the work published in Circulation Research, which we hope will keep our readers abreast of recent scientific discoveries and facilitate discussion, interpretation, and integration of the findings. These collections of articles are organized thematically and the papers listed in chronological order, beginning with the most recent ones. In each synopsis, the top ten downloaded articles (normalized to time since publication) are highlighted. Instead of using abstracts, we have elected to publish the Novelty and Significance section of each article, which we believe provides a clear précis of the salient findings and their implications in a language that is easily understandable by the non-initiated. This will enable readers who are not experts in a particular field to grasp the significance and impact of work performed in other fields. It is our hope and expectation that Thematic Synopses will help readers to gain a broader awareness and a deeper understanding of the status of research across the vast landscape of cardiovascular research.
