ABSTRACT
AIM:
We aim to determine normative reference data of phasic right atrial (RA) strain and to investigate determinants, possible clinical implications as well as feasibility and reproducibility of RA strain analysis. METHODS ANDRESULTS:
Right atrial strain was analyzed in 266 participants of the cross-sectional Berlin Female Risk Evaluation (BEFRI) study using 2D speckle-tracking echocardiography (2D STE). To determine reference values, phasic RA strain was determined in a subgroup of 123 individuals without known cardiovascular diseases or risk factors. Mean RA reservoir strain (RAS), RA conduit, and contraction strain in this reference group were 44.9 ± 11.6%, 27.1 ± 9.5%, and 17.0 ± 5.9%, respectively. Regarding possible clinical implications, RAS was significantly reduced in women with a BMI ≥ 25, compared with women with a BMI < 25 (35.5 ± 11.1% vs 43.4 ± 11.6%, P < 0.0001). RA strain analysis showed a good feasibility (92.7%); intra- and inter-observer variability was low (<5%). BMI, global longitudinal peak systolic LV strain (LVGLS%), RA area, TAPSE, and early diastolic myocardial relaxation velocity of the RV (RV-e') were significantly associated with RA mechanics in a multivariate logistic regression analysis.CONCLUSION:
In this cross-sectional trial, we determined reference values, feasibility and reproducibility, clinical and echocardiographic determinants, and possible clinical implications of RA strain analysis. Our data may help to introduce the analysis of RA mechanics into future echocardiographic routine use.Palavras-chave
