| Abstract |
The aim of the present study was to obtain reference values of maximum and minimum left atrial volumes (maxLAV and minLAV, respectively) in a population-based subset without apparent cardiovascular disease or other factors potentially associated with left atrial enlargement. Because left ventricular diastolic dysfunction is commonly found in elderly subjects, we also tried to identify the presence of possible preclinical diastolic dysfunction in the study population. A population-based sample of 168 subjects (127 men and 41 women) underwent two-dimensional echocardiography using the single-plane disc method to determine maxLAV and minLAV. maxLAV and minLAV were indexed to body surface area (maxLAVi and minLAVi, respectively). maxLAVi was independent of age and sex, and produced reference limits (mean ± 1.96 SD) of 15-37 mL/m(2). minLAVi was correlated with age, and produced estimated reference limits of 3-15 and 7-23 mL/m(2) in 40- and 80-year-old subjects, respectively. Based on the age-dependent reference values from the European Association of Cardiovascular Imaging, <5 % of the study population had possible preclinical left ventricular diastolic dysfunction. The present study established normal ranges for maxLAVi and minLAVi in a well-characterized population-based subset without apparent cardiovascular disease or other factors potentially associated with left atrial volume enlargement. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 14 September 2014.
All research outputs
#22,758,309
of 25,373,627 outputs
Outputs from The International Journal of Cardiovascular Imaging
#1,460
of 2,012 outputs
Outputs of similar age
#218,566
of 255,371 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#23
of 44 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% 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 is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
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 255,371 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 44 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
