| Abstract |
Although alterations in longitudinal systolic function have been considered the earliest sign of cardiac damage, the importance of longitudinal fractional shortening (LFS), which reflects left ventricular longitudinal contraction, has not been studied in detail. We introduce a new method of measuring LFS by echocardiography and evaluate its efficiency. Our study population consisted of 120 patients with diabetes mellitus (DM), 29 healthy volunteers, and 12 patients with coronary artery disease (CAD). LFS was assessed echocardiographically. Patients with DM underwent conventional echocardiography, assessment of left ventricular diastolic function, and pulsed-wave tissue Doppler study. LFS was 0.07 ± 0.02 in patients with CAD, 0.16 ± 0.05 in patients with DM, and 0.26 ± 0.04 in the normal controls. The three groups differed significantly with respect to the mean LFS values, which were significantly lower in patients with DM than in the normal controls. The ratio of peak diastolic velocities during early filling and atrial contraction (Em/Am) measured on pulsed-wave tissue Doppler images was significantly correlated with LFS (r = 0.37, P < 0.0001). LFS is correlated with diastolic cardiac function and is a useful and sensitive index for evaluating long-axis systolic function. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 11 April 2012.
All research outputs
#7,460,230
of 22,808,725 outputs
Outputs from Journal of Medical Ultrasonics
#28
of 176 outputs
Outputs of similar age
#31,584
of 87,585 outputs
Outputs of similar age from Journal of Medical Ultrasonics
#1
of 1 outputs
Altmetric has tracked 22,808,725 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 176 research outputs from this source. They receive a mean Attention Score of 3.4. This one has gotten more attention than average, scoring higher than 67% 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 87,585 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
