Background: The aim of this study is to descriptively evaluate ICD (Implantable Cardioverter Defibrillator) population and outcomes of ICD therapy in Armenia, and compare these to existing practice of countries in the developed world.

Methods and Results: This is a retrospective study, conducted at a single centre, which however represents complete national experience including follow-up of ICD patients. Descriptive data and ICD therapy outcomes in Primary Prevention (PP) and Secondary Prevention (SP) groups are provided. In total there were 108 ICD patients, who were evaluated throughout an average of 39 months. During follow up 34% of PP patients and 49% of SP patients had ICD interventions. Patients who experienced intervention had a lower use of statins (P<0.01), and received Amiodarone more frequently (P=0.02). Overall 23 patients (21%) died during the follow up period with 12 (11%) of them having cardiac mortality. All cause mortality did not differ between SP and PP groups.

Conclusions: Despite of low number of implants, during 39 months of follow-up, we obtained comparable results in most of the important outcomes of ICD therapy, including hospitalization, procedure- and device-related complications as well as survival.
