Abstract

BACKGROUND:

Living with an implanted cardioverter-defibrillator increases survival, but the effects of the device on health status, quality of life, and psychological state over time are not clear.

OBJECTIVES:

To investigate changes in health status, quality of life, and psychological state associated with implantation of a cardioverter-defibrillator from implantation to 4 years later.

METHODS:

A prospective, longitudinal design was used to measure changes in scores on the Short Form 36 of the Medical Outcomes Study, the Quality of Life Index-Cardiac III, and the Profile of Moods States short form at implantation, 6 months, and 1, 2, 3, and 4 years later.

RESULTS:

A total of 30 men and 11 women (mean age, 60.4 years) completed all 4 years of follow-up. The physical and mental health composite summary scores of the Short Form 36 changed significantly over time; the mental health score improved (F = 2.95; P = .03), and the physical score worsened (F = 3.69; P = .003). Scores on the Quality of Life Index-Cardiac III did not change significantly. Negative moods were significantly fewer, and the total psychological distress score was significantly lower (F = 10.21; P < .001) during the 4 years of follow-up.

CONCLUSIONS:

Patients had improved mental health and reduced psychological distress by 6 months after implantation. Perception of physical health declined during the 4 years after implantation; the role physical subscore of the Short Form 36 indicated significant improvement in functioning at 6 months and a trend toward reduced functioning at 3 and 4 years after implantation.
