Arrhythmias & electrophysiologyCohort study
Prediction of ventricular arrhythmic outcomes in suspected cardiac sarcoidosis: a comparison of cardiovascular magnetic resonance phenotyping vs. societal recommendations for implantable cardioverter-defibrillator placement
- Cohort study
- multicentre
Authors' conclusion
In patients with suspected cardiac sarcoidosis, CMR phenotyping showed greater discriminative accuracy than societal recommendations for predicting fatal or life-threatening ventricular arrhythmias
Study context
- Population
- Patients with histology-supported sarcoidosis undergoing CMR for suspected cardiac involvement, ineligible for secondary prevention implantable cardioverter-defibrillators (ICDs)84 with outcome
- Participants
- 1,514 patients
- Exposure
- CMR phenotyping vs societal recommendations for primary prevention ICD placement
- Outcome
- Composite of:
- Fatal
- Life-threatening ventricular arrhythmias
- Follow-up
- Median 4.5 years; maximum 10 years
