Main finding · LVSD (LVEF < 45%)Result — go to the resultAdjusted odds ratio 0.663 95% CI 0.261–1.685Authors' conclusion
In carriers of TTNtv, vigorous physical activity was not associated with LVSD and LTA development.
Study context
- Population
- Carriers of likely pathogenic (LP) or P titin truncating variants (TTNtv), patients and family members73% male
- Participants
- 117 carriers
- Exposure
- Athletes vs non-athletes
- Athletesn = 38
- Outcome
- LV systolic dysfunction (LVEF < 45%)
Main finding

As reported in the abstract
Observational data: associations, not effects.
Secondary outcomes
Life-threatening ventricular arrhythmias (LTA)
- Vigorous exercise not associated with LTA
- P = 0.607
Non-LTA ventricular arrhythmias
- Vigorous exercise not associated with non-LTA
- P = 0.648
Supraventricular arrhythmias (AF/AFL)
- Vigorous exercise not associated with supraventricular arrhythmias
- P = 0.701
Lifetime metabolic equivalents (METs) × hours as continuous variable
- Comparable results
