| Abstract |
To investigate the impact of a caffeine and taurine containing energy drink (ED) on myocardial contractility in healthy volunteers using cardiac MR and cardiac MR based strain analysis. 32 healthy volunteers (mean age 28 years) were investigated before and 1 h after consumption of a caffeine and taurine containing ED. For assessment of global cardiac functional parameters balanced SSFP-Cine imaging was performed, whereas CSPAMM tagging was used to evaluate global and regional myocardial strain. In addition, ten randomly chosen subjects were investigated once more using a caffeine only protocol to further evaluate the effect of caffeine solely. Heart rate and blood pressure were recorded throughout all studies. ED consumption led to a significant increase in peak systolic strain (PSS) and peak systolic strain rate (PSSR) 1 h after consumption (PSS: w/o ED -22.8 ± 2.1 %; w ED -24.3 ± 2.4 %, P = <0.0001 and PSSR: w/o ED -1.2 ± 0.1 1/s; w ED -1.3 ± 0.2 1/s, P = 0.0056), which was not observed in the caffeine only group. In contrast, global left ventricular function was unchanged (P = 0.2076). No significant changes of vital parameters and diastolic filling pattern were detected 1 h after ED consumption. Consumption of a caffeine and taurine containing ED results in a subtle, but significant increase of myocardial contractility 1 h after consumption. |

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 24 January 2015.
All research outputs
#16,722,190
of 25,374,917 outputs
Outputs from The International Journal of Cardiovascular Imaging
#802
of 2,012 outputs
Outputs of similar age
#217,122
of 369,757 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#9
of 31 outputs
Altmetric has tracked 25,374,917 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 369,757 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 31 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 67% of its contemporaries.
