Implication
Patients with ICDs for stable VT face ongoing arrhythmia and mortality risks; leaves open net benefit versus medical therapy alone.
Structured PICO
What is the long-term risk of unstable ventricular arrhythmias and mortality in patients receiving ICDs for stable VT?
P
Population
82 patients who received implantable cardioverter defibrillators (ICDs) for hemodynamically stable ventricular tachycardia (VT), mean age 66.1 +/- 11.3 years, mean LVEF 32.3% +/- 11.2%.
I
Intervention
Implantable cardioverter defibrillator (ICD)
O
Outcome
Future risk of unstable ventricular arrhythmias and survivalhard clinical
Patients presenting with hemodynamically stable VT are at significant risk for subsequent unstable VT, supporting the use of ICDs in this population despite a high rate of inappropriate shocks and complications.
