| Abstract |
New-onset atrial fibrillation (NOAF) is a common finding in patients with myocardial infarction (MI), but few studies are available regarding the prediction model for its risk estimation. Although Global Registry of Acute Coronary Events (GRACE) risk score (RS) has been recognized as an effective tool for the risk evaluation of clinical outcomes in patients with MI, its usefulness in the prediction of post-MI NOAF remains unclear. In this study, we sought to validate the discrimination performance of GRACE RS in the prediction of post-MI NOAF and to make a comparison with that of the CHA2DS2-VASc score in patients with ST-segment elevation myocardial infarction (STEMI). A total of 488 patients with STEMI who were admitted to our hospital between May 2015 and October 2016 without a history of atrial fibrillation were retrospectively evaluated in this study. GRACE and CHA2DS2-VASc scores were calculated for each patient. Patients were divided into low (GRACE RS≤125)-, intermediate (GRACE RS 126-154)-, and high (GRACE RS≥155)-risk groups. Receiver operating characteristic curve analyses were performed to evaluate the discrimination performance of both RSs. Model calibration was evaluated by using Hosmer-Lemeshow goodness-of-fit test (HLS). Of the 488 eligible patients, 49 (10.0%) developed NOAF during hospitalization. In the overall cohort, the discrimination performance of GRACE RS (C-statistic: 0.76, 95% CI: 0.72-0.80) was significantly better than that of CHA2DS2-VASc score (C-statistic: 0.68, 95% CI: 0.64-0.72; comparison p=0.03). For subgroup analysis, GRACE RS tended to be better than the CHA2DS2-VASc score in all but the intermediate-risk group as evidenced by C-statistics of 0.60 and 0.65 for GRACE and CHA2DS2-VASc scores, respectively. Excellent calibration was achieved except for GRACE RS in females (HLS p=0.05). The diagnostic performance of GRACE RS is relatively high as well as better than that of the CHA2DS2-VASc score with respect to the prediction of post-MI NOAF. |

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 22 June 2018.
All research outputs
#16,728,456
of 25,382,440 outputs
Outputs from Clinical Interventions in Aging
#1,182
of 1,968 outputs
Outputs of similar age
#210,279
of 342,877 outputs
Outputs of similar age from Clinical Interventions in Aging
#28
of 38 outputs
Altmetric has tracked 25,382,440 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 1,968 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.1. This one is in the 36th percentile – i.e., 36% 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 342,877 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 38 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
