| Abstract |
-In heart failure and reduced ejection fraction (HFrEF), the prognostic role of heart rate (HR) in atrial fibrillation (AF) is unknown and the effectiveness of beta blockers has recently been questioned in AF. -By access to Swedish Heart Failure registry patients with HFrEF (n=18 858) were divided into sinus rhythm (SR) (n=11 466) or AF (n=7392). The endpoint was all-cause mortality. Compared to HR ≤ 60 bpm, the adjusted hazard ratios for mortality in SR were 1•26 for HR 61-70 bpm, 1•37 for HR 71-80 bpm, 1•52 for HR 81-90 bpm, 1•63 for HR 91-100 bpm and 2•69 for HR >100 bpm. However, in AF, the hazard ratio was increased only in HR > 100 bpm (1•30, p = 0•001) compared to HR ≤ 60 bpm. Beta-blocker use was associated with reduced mortality in SR (hazard ratio 0•77, p = 0•011), and in AF (hazard ratio 0•71, p < 0•001). In beta-blocker use in SR, hazard ratio gradually increased with HR increment whereas in AF hazard ratio was significantly increased only in HR > 100 bpm (1•29, p = 0•003) compared to HR ≤ 60 bpm. -In patients with HFrEF, a higher HR was associated with increased mortality in SR, and in AF only if > 100 bpm. Beta-blocker use was associated with reduced mortality both in SR and AF. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. 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 06 August 2021.
All research outputs
#6,301,140
of 25,450,869 outputs
Outputs from Circulation: Heart Failure
#729
of 1,543 outputs
Outputs of similar age
#66,538
of 276,159 outputs
Outputs of similar age from Circulation: Heart Failure
#14
of 26 outputs
Altmetric has tracked 25,450,869 research outputs across all sources so far. Compared to these this one has done well and is in the 75th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,543 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 20.9. This one has gotten more attention than average, scoring higher than 52% 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 276,159 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 75% of its contemporaries.
We're also able to compare this research output to 26 others from the same source and published within six weeks on either side of this one. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
