[Turkey's 2009 output of cardiovascular publications shows a four-year regression].
The output of publications in cardiovascular medicine during 2009 originating from Turkey's institutions were evaluated based on data of the Web of Knowledge. Only original articles and reviews appearing full-text in source publications of Science Citation Index CD Edition were included. A weighted credit system was used for items published jointly by multiple departments or with a noncardiological Turkish institution. Turkey's publications declined substantially to 167 articles and reviews, with a parallel decrease in her share of world publication from 10.8 to 8.2 per mille. Six-sevenths of the output originated from adult cardiology. The median impact factor of 2.18 was higher roughly by 17% than in the previous year; half of the publications appeared in periodicals with an impact factor of 1.27 to 3.12, reflecting a consistent qualitative improvement. University medical faculties persisted to lag behind in productivity, while the Gülhane Military Medical Academy led by far, runners-up being the Turkish Society of Cardiology, Kartal Koşuyolu Research Hospital, and medical faculties of Başkent University and Istanbul University.
