Discussion

Implication

Noninducibility linked to higher sudden death in DCM; challenges PVS prognostic value and leaves open better risk stratification.

Key Points

This study investigates the utility of programmed ventricular stimulation (PVS) to assess risks in patients with idiopathic dilated cardiomyopathy (DCM) and ventricular tachyarrhythmias.
Evaluated 102 patients with DCM and documented sustained ventricular tachycardia (VT) or ventricular fibrillation (VF).
Induction of VT/VF during programmed ventricular stimulation was assessed.
Follow-up conducted for 32 months on the incidence of sudden cardiac death.
Sustained VT was induced in 43% of patients with documented VT and 36% with documented VF (ns).
Sudden death occurred in 14% of patients at mean follow-up, with a higher incidence in non-inducible patients (29% vs 6%, P < 0.05).
The implantation of a cardioverter defibrillator (ICD) showed significant reduction in sudden death rate, with only 3% mortality in ICD patients.

Structured PICO

Does programmed ventricular stimulation predict sudden death in patients with idiopathic dilated cardiomyopathy and documented sustained ventricular tachyarrhythmias?

Population

102 patients with idiopathic dilated cardiomyopathy (DCM) and documented sustained ventricular tachycardia (VT; n = 63) or ventricular fibrillation (VF; n = 39)

Intervention

Programmed ventricular stimulation (PVS)

Comparator

Patients without inducible VT/VF

Outcome

Inducibility of sustained VT or VF and incidence of sudden deathhard clinical

In patients with idiopathic dilated cardiomyopathy and documented sustained ventricular tachyarrhythmias, programmed ventricular stimulation has limited prognostic value for predicting sudden death.
