The Impact Factor of Circulation Research Rises 25%
The 2012 Impact Factor (IF) of Circulation Research surged to 11.861 - a 25% increase over the 2011 value of 9.489. This is, by far, the highest IF ever for the journal (the previous high value was 10.117 in 2003). It is also the biggest annual increase in IF in the history of Circulation Research. A similar increase occurred in the Immediacy Index (number of citations in a given year to papers published in the same year), which rose 22% (from 2.023 in 2011 to 2.465 in 2012). [Extract]
