Clinical Impact of Arrhythmias Detected by an Implantable Cardiac Monitoring Device With Real-Time Transmission Among Patients With Early Reduced Left Ventricular Ejection Fraction After ST-Segment Elevation Acute Myocardial Infarction: The TeVeO Study
Authors' conclusion
The incidence and burden of ventricular arrhythmias were lower than expected. AF was associated with an increased mortality.
Study context
- Population
- Patients who survived STEMI with reduced left ventricular ejection fraction (LVEF), monitored with an implantable cardiac monitor (ICM) after dischargeenrolled (35%) of 636 with LVEF ≤40% on day 4 or later, from 3,565 patients discharged after STEMI
- Participants
- 224 patients
- Outcome
- Mortality rate
- Follow-up
- Median of 3.1 years
Main finding
As reported in the abstract
Mortality rate
3.7 per 100 patient-years
Observational data: associations, not effects.
Further findings
Implantable cardioverter-defibrillator (ICD) implantation · 6 months

- 2
Ambulatory arrhythmias · During follow-up
- At least 1 ambulatory arrhythmia
- 119 patients (53%)
- Atrial fibrillation (AF)
- 39 (17%)
- Nonsustained ventricular tachycardia
- 35 (16%)
- Sinus pauses >3 seconds
- 33 (15%)
- Second-or third-degree atrioventricular block
- 14 (6%)
- Sustained monomorphic ventricular tachycardia/appropriate ICD therapy

Incidence rates of ventricular arrhythmias
Per 100 patient-years
- Nonsustained ventricular tachycardia
- 5.4
- Sustained monomorphic ventricular tachycardia/appropriate ICD therapy
- 0.9
Association of AF with mortality
- Only AF was independently associated with increased mortality (adjusted HR)
- 2.5; P = 0.04
