Implantable Cardioverter-Defibrillator Registry Risk Score Models for Acute Procedural Complications or Death After Implantable Cardioverter-Defibrillator Implantation
Key result
A 10-variable clinical risk score stratified the risk of in-hospital complications after ICD implantation, with event rates ranging from 0.6% for scores ≤5 to 8.4% for scores ≥19.
Why the study?
Can a simple risk score identify patients at high and low risk of acute procedural complications or death after ICD implantation?
Population
268,701 ICD implants submitted to the ICD Registry

Structured PICO
Can a simple risk score identify patients at high and low risk of acute procedural complications or death after ICD implantation?
P
Population
268,701 patients undergoing implantable cardioverter-defibrillator implantation from a registry, evaluated for acute procedural complications or in-hospital death.
E
Exposure
10-variable risk score model (age ≥ 70 years, female, NYHA class III or IV, atrial fibrillation, prior valve surgery, chronic lung disease, BUN >30, reimplantation for reasons other than battery change, ICD type dual chamber or biventricular, and nonelective ICD implant)
O
Outcome
Acute procedural complications and/or in-hospital deathcomposite
Main Result
Absolute Event Rate: 8.4% vs 0.6%
A simple 10-variable risk score can effectively stratify patients by their risk of acute in-hospital complications or death following ICD implantation, aiding in patient selection and post-procedure care planning.
Cite This Study
Haines et al. (2011) conducted an observational in Implantable cardioverter-defibrillator (ICD) implantation (n=268,701). 10-variable clinical risk score vs. Low risk score (≤ 5) was evaluated on Acute complications and/or in-hospital death. A 10-variable clinical risk score stratified the risk of in-hospital complications after ICD implantation, with event rates ranging from 0.6% for scores ≤5 to 8.4% for scores ≥19.
