Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Background: Elevated heart rate (HR) is an independent risk factor for all-cause death or cardiovascular events in non-hemodialysis subjects; however, the clinical significance of elevated HR in hemodialysis patients is not well studied. Methods: We prospectively evaluated the relationship between HR and adverse outcome in a total of 229 ambulatory hemodialysis patients (57 % men; mean age 62.2 years) recruited from two dialysis clinics in 2009. Mean (SD) HR of this cohort was 74.1 (11.0) beats per minute (bpm). Results: Receiver operating characteristic curves identified an HR cut-off level of ≥80 bpm for increased adverse outcome. After a mean follow-up of 525 days (range 7-760 days) a total of 30 primary endpoints (21 all-cause deaths, 4 acute coronary syndromes and 8 strokes) and 38 secondary endpoints (30 primary endpoints, 8 congestive heart failures, and 5 other cardiovascular events) were detected. Cox regression analysis revealed that HR >80 bpm was not an independent predictor of primary endpoints [hazard ratio 1.81, 95 % confidence interval (CI) 0.79-4.11, p = NS], but of secondary endpoints (hazard ratio 2.01, 95 % CI 1.01-4.22, p < 0.05) after adjusting for age, sex, hemodialysis duration, and cardiovascular risks. Conclusions: Elevated HR is an independent predictor of all-cause death and cardiovascular events in Japanese ambulatory hemodialysis patients. © 2012 Japanese Society of Nephrology.
