The Effect of Coronary Bypass Graft Surgery for the Prevention of Sudden Cardiac Death: Recurrent Episodes After ICD Implantation and Review of Literature
Why the study?
Does concomitant CABG surgery reduce recurrent episodes of ventricular tachycardia in patients receiving an ICD after out-of-hospital cardiac arrest?
Population
75 patients who experienced out-of-hospital cardiac arrest (n=64 in ICD alone group, n=11 in ICD + CABG group)
Comparison
Implantable cardioverter defibrillator… vs ICD implantation alone
Design
Cohort
Follow-up
up to 18 months

Implication
Concomitant CABG showed a nonsignificant trend toward fewer VT episodes; leaves open whether revascularization reduces arrhythmia burden and warrants randomized trials.
Structured PICO
Does concomitant CABG surgery reduce recurrent episodes of ventricular tachycardia in patients receiving an ICD after out-of-hospital cardiac arrest?
P
Population
75 patients who experienced out-of-hospital cardiac arrest (n=64 in ICD alone group, n=11 in ICD + CABG group)
I
Intervention
Implantable cardioverter defibrillator (ICD) implantation and concomitant coronary artery bypass graft (CABG) surgery
C
Comparator
ICD implantation alone
O
Outcome
Number of recurrent episodes of ventricular tachycardia (VT) per patient based on ICD recordingshard clinical
Although not statistically significant, concomitant CABG with ICD implantation showed a trend toward fewer recurrent VT episodes compared to ICD alone in survivors of out-of-hospital cardiac arrest.
