title: Spanish implantable cardioverter-defibrillator registry. 5th official report of the spanish society of cardiology working group on implantable cardioverter-defibrillators (2008).
abstract: OBJECTIVE
  To summarize the findings of the Spanish Implantable Cardioverter-Defibrillator (ICD) Registry for 2008 compiled by the Spanish Society of Cardiology Working Group on Implantable Cardioverter-Defibrillators.
  
  
  METHODS
  Prospective data recorded voluntarily on single-page questionnaires were sent to the Spanish Society of Cardiology by each implantation team.
  
  
  RESULTS
  Overall, 3486 device implantations were reported, which is 84.7% of the estimated total number of implantations. The reported implantation rate was 76 per million population and the estimated total implantation rate was 90 per million. The proportion of first implantations was 78.1%. There continued to be substantial regional variations within Spain. The majority of ICD implantations took place in men (mean age 62+/-12 years) who had severe or moderate-to-severe ventricular dysfunction and were in New York Heart Association functional class II. Ischemic heart disease was the most frequent underlying cardiac condition, followed by dilated cardiomyopathy. The number of indications for primary prevention increased relative to the previous year, especially in patients with ischemic cardiomyopathy, and now account for 57% of first implantations. The types of ICD implanted were unchanged from 2007. Overall, 73.6% of ICDs were implanted by cardiac electrophysiologists.
  
  
  CONCLUSIONS
  The 2008 Spanish ICD Registry includes data on almost 85% of all ICD implantations performed in Spain. Although the number has continued to increase, it still remains far from the European average. There was a significant increase in indications for primary prevention. Substantial regional variations continue to exist within Spain.
