title: [Status of cardiac resynchronization therapy in Catalonia, Spain: Results of the prospective multicentric study TRC-CAT].
abstract: OBJECTIVE
  Results of cardiac resynchronization therapy (CRT) have been extensively published. However, there is limited data in unselected populations. The objective of the study was to analyse the efficacy and safety of CRT in Catalonia.
  
  
  METHODS
  A prospective study was performed of consecutive patients implanted with CRT over one year in 7 university hospitals in Catalonia, representing 90% of the implanted patients. Echocardiographic reverse remodelling was defined as 5 points improvement in left ventricular ejection fraction and clinical responders were defined as patients with an increase>10% of six-minute walk test or one point of New York Heart Association functional class at 12 months. Patients were followed up for one year and hospital admissions and mortality were analyzed.
  
  
  RESULTS
  Of the 200 patients included in the study, 99% met the indications of the current CRT clinical guidelines and 68% received CRT with implantable cardioverter-defibrillator. The rate of complications was 12.5%. During follow-up 16 patients (8%) died. Fifty-two percent (104) of the population was considered to respond clinically and 62% (124) presented improved echocardiographic parameters. Compared to the year prior to implant, hospital admissions decreased by 82% (P<.001).
  
  
  CONCLUSIONS
  In an unselected population of Catalonia, we observe that CRT was effective and decreased the number of hospital admissions.
