Implantable Heart Defibrillator Prolongs Life Expectancy – Part 2 of 3
The findings trunk from a survival analysis (involving data collected since 2005 by a large national Medicare registry) following implantation with the small electrical devices known as implantable cardioverter-defibrillators (ICDs) that are connected by wire to the pith and designed to provide a life-saving electronic pulse if and when the heart stops beating. The research team compared the discharge of such devices among more than 5300 real-world patients with the performance observed among more than 1500 patients who had participated in clinical defibrillator studies.
The authors stressed that the demographics of the two groups were comparable, with no only sick or elderly individuals included in the real-world pool. But while the analysis revealed comparable results among both groups, the authors stressed that their findings clearly could not discourse to how older and sicker patients might fare outside the confines of a study situation, which itself often favors the inclusion of younger/healthier patients.
