Abstract

Frequent idiopathic premature ventricular complexes (PVCs) can result in a reversible form of cardiomyopathy. The impact of variability in PVC frequency throughout the day on PVC-induced cardiomyopathy was assessed. The subjects of this study were 107 consecutive patients (58 men [54%], mean age 49.7±15.0 years, ejection fraction: 50.4±11.4%) referred for ablation of frequent PVCs. All patients had a 24 hour Holter prior to the ablation procedure. The circadian variation in PVC burden was determined and correlated with the presence or absence of cardiomyopathy. A total of 43 patients (40%) had cardiomyopathy. Patients with cardiomyopathy had an ejection fraction of 38.4±6.9%, a higher PVC burden (28.5±11.5% vs 19.5±10.5%, p=0.0001), less variability in circadian PVC distribution (Coefficient of variation (CoV) hourly: 31.5±21% vs 59.8±32.4%, p=0.0001), more frequent interpolated PVCs (20 patients [47%] vs 15 patients [23%], p=0.022), and were more frequently asymptomatic compared to patients without cardiomyopathy (56% vs 19%, p=0.0001). By multivariate analysis, consistency in PVC burden throughout the day was an independent predictor of PVC-induced cardiomyopathy (OR 16.3, 95% CI 1.115-155.3, p=0.015). In patients with frequent PVCs, consistency in hourly PVC frequency throughout the day is an independent predictor of PVC-induced cardiomyopathy.

Attention Score in Context

This research output has an Altmetric Attention Score of 12. 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 10 May 2018.
All research outputs
#1,066,708
of 11,841,013 outputs
Outputs from Heart Rhythm
#193
of 1,832 outputs
Outputs of similar age
#48,370
of 316,473 outputs
Outputs of similar age from Heart Rhythm
#12
of 43 outputs
Altmetric has tracked 11,841,013 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 90th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,832 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one has done well, scoring higher than 89% 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 316,473 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 84% of its contemporaries.
We're also able to compare this research output to 43 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 72% of its contemporaries.
