| Abstract |
Although many echocardiographic studies are available about the adaptation of left ventricle to intensive training, right heart function has been poorly investigated and no data are available about the right atrial (RA) function in top-level athletes. The aim of the study was to investigate RA function and dimension by standard echocardiography and 2D speckle tracking echocardiography (STE). One hundred top-levels athletes were recruited from professional sports team and were compared with 78 normal subjects. Athletes during an off-training period or during prolonged forced rest resulting from injuries were excluded. Top-level athletes had higher BSA as compared with controls and, as expected, a lower resting heart rate (p ≤ 0.001). RA area, volume, and volume index were significantly greater in athletes than in controls (p ≤ 0.001). This increase was associated with greater right ventricular and inferior vena cava diameters (p ≤ 0.001). Peak atrial longitudinal strain and peak atrial contraction strain values were significantly lower in athletes in comparison with controls (40.92 ± 9.86% vs. 48.00 ± 12.68%, p ≤ 0.001; 13.05 ± 4.84% vs. 15.99 ± 5.74%, p ≤ 0.001, respectively). Interestingly, while athletes presented a higher E/A ratio (p ≤ 0.001) and a lower peak A velocity (p ≤ 0.001), the E/e' ratio did not differ between the two groups. In top-level athletes the RA presents a physiological adaptation to intensive exercise conditioning which determines not only a morphological but also a functional remodeling. We reported for the first time reference values of RA strain in elite athletes, demonstrating that 2D STE is a useful tool to investigate RA longitudinal myocardial deformation dynamics in athlete's heart. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 July 2013.
All research outputs
#16,721,208
of 25,373,627 outputs
Outputs from The International Journal of Cardiovascular Imaging
#802
of 2,012 outputs
Outputs of similar age
#112,350
of 176,395 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#8
of 20 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,012 research outputs from this source. They receive a mean Attention Score of 2.3. This one has gotten more attention than average, scoring higher than 54% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 176,395 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 20 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
