Implantable cardioverter defibrillators for primary prevention of sudden cardiac death in elderly and senile patients
Abstract
Sudden cardiac death (SCD) is one of the most difficult problem in modern cardiology. Implantable cardioverter–defibrillators (ICDs) have been shown to be an effective therapy option for the primary prevention of SCD in patients at high risk. However, the effectiveness of the ICD when used in routine clinical practice in patients with chronic heart failure is uncertain. This is particularly true for elderly patients.
The aim was to study the effectiveness of the ICD for primary prevention on survival in elderly and senile patients (from 60 to 90 years).
Material and methods. Our study included 100 patients with indications to ICD for primary prevention of SCD. Patients was divided in 2 groups: the first group included 49 patients with ICD (average age 68.7±4.7 years), the second group included 51 patients with indications for the procedure, but they didn't receive ICD (average age 70.2±2.9 years). The clinical characteristics of patients did not differ between groups. After 36 months in the first group survival was significantly higher than in the second one. Mortality in the first group was 14.2% (7 patients) vs 31.3% (16 patients) in the second group (p=0.026).
Conclusion. ICD therapy in elderly and senile patients can be effective in the primary prevention of SCD.
