Original Article



ICD implantation for primary prevention of sudden cardiac death in patients with left ventricular systolic dysfunction (ejection fraction ≤35%) has increased since the publication of the SCD-HEFT and MADIT-II data. The aim of this study is to examine the effectiveness and safety of prophylactic ICD use in a community heart failure population and to assess the impact on patient’s quality of life.

Methods and results

Seventy-one ICDs were inserted between the years 2002 and 2006. The mean follow-up from time of insertion was 24 ± 11 months. Eighteen patients (25%) had potentially life-saving therapy. Seven (10%) patients received inappropriate shocks. Complications were encountered in five patients (7%).


In a community heart failure population, prophylactic ICD implantation is associated with a high incidence of life-saving therapy, a low complication rate and a high level of tolerability. These data indicate translation of clinical trial benefits to the general heart failure population.
