| Abstract |
Aim of this study was to investigate the relationship between (18)F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) findings and serological biomarkers of inflammation and the related discriminant value of unfavourable outcome during follow-up in patients with acute aortic syndromes (AAS). Sixty patients with AAS underwent PET-CT imaging during the hospitalization along with measurement of C-reactive protein (CRP) and D-dimer (D-d) serum levels. An aortic wall pathology was considered PET-positive by a maximum standardized uptake value (SUVmax) >2.5. A combined endpoint of major adverse events (MAE) including aorta-related mortality, disease progression and re-intervention was used to compare patient subgroups at 3-year follow-up. PET-CT detected an elevated FDG uptake within the aortic wall in 25 (41.7 %) patients. PET-positive patients showed significantly increased CRP levels (10.0 ± 6.6 mg/dL) and tended to higher D-d levels (5.1 ± 3.9 mg/L), compared to PET-negative patients (5.8 ± 6.1 mg/dL and 3.1 ± 4.7 mg/L respectively; P = 0.048, P = 0.19). At 3-year follow-up, all-cause mortality and MAE were higher in the PET-positive (21.7 and 47.8 % respectively) than PET-negative group (0.0 and 13.3 % respectively; P = 0.012, P = 0.006). On Kaplan-Meier analysis, PET-positive patients were at higher risk of MAE (P = 0.031). This tendency was more evident by combining PET results with D-d levels at a cutoff value of 4.8 mg/L (P < 0.001). In patients with AAS, a pathological glucose uptake in aortic wall lesions by PET-CT was associated with high CRP levels and increased mortality and MAE at 3-year follow-up. The combination of PET results with D-d levels had the best discriminant value of MAE. |

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 31 July 2015.
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
#235,376
of 275,423 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#34
of 54 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 275,423 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 54 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.
