| Abstract |
The CHA2DS2-VASc score is often used for stroke risk stratification in atrial fibrillation (AF) patients. However, its usefulness in patients ≥75 years of age with or without AF is unclear. We aimed to investigate whether the CHA2DS2-VASc score can predict ischemic stroke (IS), transient ischemic attack, thromboembolism (TE), and mortality in elderly patients with and without AF. During 2013-2014, 1,071 patients (36.3% with concomitant AF) at least 75 years old were enrolled, and the follow-up ended on July 15, 2017. Variables included sociodemographic characteristics, complications, drugs taken, laboratory results, and echocardiographic parameters. The primary end points were IS, transient ischemic attack, and TE, expressed as IS/TE. All-cause mortality was a secondary end point. Survival curves and mortality risks were assessed via Kaplan-Meier survival analysis and compared by log-rank tests. The average follow-up duration was 2.57±1.37 years. Overall, 167 patients (5.6%) died and 77 (7.2%) developed IS/TE. The CHA2DS2-VASc score was associated with IS/TE in patients 75 years or older with and without AF, and patients with a CHA2DS2-VASc score ≥5 had a higher risk of stroke. However, the CHA2DS2-VASc score was not related to all-cause mortality. The CHA2DS2-VASc score can predict IS/TE, but not mortality, in elderly patients (≥75 years) with or without AF. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. 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 27 April 2021.
All research outputs
#7,782,070
of 25,382,440 outputs
Outputs from Clinical Interventions in Aging
#736
of 1,968 outputs
Outputs of similar age
#126,367
of 344,853 outputs
Outputs of similar age from Clinical Interventions in Aging
#21
of 51 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
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 has gotten more attention than average, scoring higher than 62% 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 344,853 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 62% of its contemporaries.
We're also able to compare this research output to 51 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 58% of its contemporaries.
