quality of life after AICD

Jill Vesty, Kismet D Rasmusson, Jill Hall, Sandy Schmitz, Sally Brush
PURPOSE: To review the use of cardiac resynchronization therapy (CRT) and automatic implantable cardiac defibrillators (AICDs) in heart failure (HF) patients. DATA SOURCES: Selected scientific literature. CONCLUSIONS: New developments in device therapy for HF patients are helping to decrease morbidity and mortality in this challenging patient population. CRT improves left ventricular (LV) ejection fraction, quality of life, 6-min walk distances, and New York Heart Association scores in select patients...

In a press conference on Nov. 20, 2001 it was announced that the Multi-center Autonomic Defibrillator Implantation Trial II (MADIT II) was stopped early because of a 30% reduction in mortality in patients randomised to receive an implantable defibrillator device. The 4 year multi-centre trial of 1200 patients was terminated early after an independent board observed that the post-MI patients with impaired left ventricular function receiving the implantable defibrillator had improved survival rates compared to those receiving conventional treatment...

Judgement about cost-effectiveness of medical treatments depends upon the criteria used to define effectiveness. The most rational single criterion is the Quality Adjusted Life Year gained (QALY). Comparisons of cost-effectiveness of treatments may be made by comparing the dollar costs per QALY. Both the dollar and the QALY comparisons are subject to all errors of biological variable measurement and bias introduced by experimental design seen in other biological experiments. The proper methodology for comparison is the prospective randomised controlled clinical trial...
