title: Cardiovascular scientific production in Spain and in the European and global context (2003-2007).
abstract: OBJECTIVE
  The publication of research articles has increased considerably in recent years in all biomedical fields. The present study examines the position of Spanish quality research in cardiology in the European and world context, and its evolution during the 5-year period 2003-2007.
  
  
  METHODS
  Using the Science Citation Index Expanded of Thomson Reuters as data source, we compared Spanish cardiovascular scientific production with that of the rest of countries in the European Union and of the most important countries worldwide, along with relative productivity as per number of inhabitants and Gross Domestic Product, and the number of citations in the journals of the <<Cardiac and Cardiovascular Systems>> area of the Journal Citation Reports (CCS-JCR).
  
  
  RESULTS
  Spain ranks sixth in the European Union and ninth worldwide in scientific production (tenth worldwide if only the journals of the first quartile of the CCS-JCR area are considered). As regards the number of citations received, Spain ranks seventh in the European Union and eleventh worldwide. In terms of relative productivity as per number of inhabitants and Gross Domestic Product, the Spanish ranking is less favorable (positions 15 and 18, respectively).
  
  
  CONCLUSIONS
  The ranking of Spanish cardiovascular research is similar to that of other biomedical fields, though its position is less favorable in relation to certain demographic and economical indicators. In order to maintain adequate investigational levels, it is necessary for the European governments and scientific societies to regard the promotion of high-quality cardiological research as a priority concern.
