Cross-sectional study
Echocardiographic Reference Ranges of Global Longitudinal Strain for All Cardiac Chambers Using Guideline-Directed Dedicated Views
- Cross-sectional study
- population-based
- HUNT4Echo substudy
Authors' conclusion
Reference ranges of strain for all cardiac chambers were established based on guideline-directed chamber-specific recordings. Age and sex were the most important factors influencing reference ranges
Study context
- Population
- Healthy participants from HUNT4Echo, the echocardiographic substudy of the 4th wave of the Trøndelag Health Studyhealthy
- Participants
- 1,329 participants
- Outcome
- Reference ranges (incl. lower normal limits) of global strain for all 4 cardiac chambers by guideline-directed dedicated views
Main finding
As reported in the abstract
Strain reference ranges
Left ventricular (LV) global longitudinal strain
−24% to −16%
RV free-wall strain
−35% to −17%
Left atrial (LA) reservoir strain
17% to 49%
Right atrial (RA) reservoir strain
17% to 59%
Observational data: associations, not effects.
Further findings
Strain feasibility
- LV
- 96%
- RV
- 83%
- LA
- 94%
- RA
- 87%
Influence of subject characteristics
- All strains lower absolute values with higher age, except LA and RA contractile strains, which were higher
- All chamber-specific strains associated with age; LV strain associated with sex
