| Abstract |
Optical frequency domain imaging (OFDI) was utilized to compare the prevalence of neoatherosclerosis (NA) and morphological characteristics of the neointimal tissue in second generation drug eluting stent (G2-DES)-treated lesions between early (<1 year, E-ISR) and late (>1 year, L-ISR) in-stent restenotic phases. Data comparing NA and in vivo tissue characteristics between early and late in-stent restenosis (ISR) after implantation of G2-DES is limited. An OFDI analysis was performed in 50 G2-DESs {35 everolimus-eluting stent [22 cobalt-chromium (CoCr), 13 platinum-chromium (PtCr)], and 15 biolimus-eluting stent [BES]} ISR lesions (46 consecutive patients) undergoing target lesion revascularization, classified as E-ISR (n = 22 lesion) and L-ISR (n = 28 lesion). NA, defined as a neointima formation containing lipids or calcification was observed in fewer than half (24/50) of all ISR lesions with no significant difference between E-ISR and L-ISR lesions (50 vs. 46.4%, p = 0.8). There were also no significant differences in the morphological appearance and tissue characteristics between E-ISR and L-ISR lesions. ISR was more likely to occur earlier [median 8.6 (8.3-8.9) months] after PtCr-EES implantations (12 lesions vs. 1, p < 0.001), while 3/4 of the BES ISR lesions and more than 2/3 of the CoCr-EES ISR lesions were observed after 1 year of implantation [median 21.3 (20.7-27.5) months, p < 0.001]. Acknowledging some limitations, our observations may suggest that the prevalence of neoatherosclerosis and the morphological appearance, and tissue characteristics of G2-DESs restenotic lesions are similar between the early and late restenotic phases. Certain platforms (PtCr-EESs) may have preferentially presented with early ISR. |

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 12 November 2017.
All research outputs
#19,951,180
of 25,382,440 outputs
Outputs from The International Journal of Cardiovascular Imaging
#1,116
of 2,012 outputs
Outputs of similar age
#233,558
of 323,623 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#34
of 65 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% 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 35th percentile – i.e., 35% 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 323,623 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 65 others from the same source and published within six weeks on either side of this one. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
