When “sudden cardiac death” is not so sudden:Lessons learned from the automatic implantable defibrillator

Q: What is the clinical evidence from this study?

Study design: Observational. Population: Congestive heart failure (n=384). Intervention: Advanced congestive heart failure (NYHA class III) vs. Mild to moderate heart failure (NYHA class 0-II). Primary outcome: Eligibility for biventricular pacing.

Implication

May warrant CRT eligibility screening in ICD recipients; leaves open whether combined devices improve outcomes.

Study Design

Type

Observational (n=384)

Structured PICO

Population

384 patients (mean age 59 years, 16.1% female) at the time of ICD implantation, retrospectively analyzed to determine eligibility for biventricular pacing.

Outcome

Proportion of patients fulfilling eligibility criteria for biventricular pacing

A significant proportion of patients receiving ICDs (7.3% to 12.5%) meet criteria for biventricular pacing, suggesting that combined devices may be beneficial for these patients.

Guarnieri et al. (1988) conducted an observational in Congestive heart failure (n=384). Advanced congestive heart failure (NYHA class III) vs. Mild to moderate heart failure (NYHA class 0-II) was evaluated on Eligibility for biventricular pacing. Among 384 patients with an ICD, 7.3% to 12.5% fulfilled eligibility criteria for biventricular pacing, indicating a significant proportion may benefit from this approach.
