Arrhythmias & electrophysiology
Programmed ventricular stimulation for risk stratification in patients with myocardial scarring and mildly reduced or preserved ejection fraction
Authors' conclusion
PVS is a useful tool to discriminate patients with myocardial scar and LVEF of ≥40% at an increased arrhythmic risk.
Study context
- Population
- Patients with myocardial scarring and left ventricular ejection fraction (LVEF) ≥40% who underwent programmed ventricular stimulation (PVS)
- Participants
- 168 patients
- Comparison
- Positive vs negative PVS
- Positive PVSn = 21
- Outcome
- Major arrhythmic event:
- SCD
- VT/VF
- Appropriate ICD therapy
- Follow-up
- Mean 46 ± 38 months
