Some observational studies of the general population showed that resting heart rate was associated with mortality. However, the relationship was unclear in dialysis patients.
The study was a multicentre prospective cohort analysis including 1102 patients. Patients were classified into four groups based on resting heart rate just before starting the first dialysis session: <60/min; 60-79/min; 80-100/min; and ≥101/min. All-cause mortality, cardiovascular (CV) related mortality, and incidences of CV events after dialysis initiation were compared using the log-rank test. All-cause mortality rates for patients with heart rates <60, 60-79, and ≥101/min were compared to those for patients with heart rates 80-100/min, using multivariate Cox proportional hazard regression analysis. Moreover, we compared the outcomes among patients without use of β-blocker or heart failure symptom at the first dialysis session.
Significant differences were observed in the all-cause mortality rates among the four groups (P = 0.007). Multivariate analysis revealed that all-cause mortality was significantly higher in patients with heart rate ≥ 101/min than in patients with heart rate 80-100/min (hazard ratio [HR] = 2.30, 95% confidence interval [CI]: 1.25-4.23). Subgroup analysis showed that among patients without use of b-blocker or heart failure symptom, all-cause mortality rates for those with heart rates ≥101/min were significantly higher than in patients with heart rate 80-100/min (HR = 2.98, 95% CI: 1.51-5.88, HR = 3.65, 95% CI: 1.59-8.36, respectively).

一些针对普通人群的观察性研究表明静息心率与死亡率相关。然而,在透析患者中这种关系尚不清楚。
本研究为多中心前瞻性队列分析,纳入1102例患者。根据首次透析 session 开始前的静息心率将患者分为四组:<60次/分钟;60 - 79次/分钟;80 - 100次/分钟;≥101次/分钟。使用对数秩检验比较透析开始后的全因死亡率、心血管(CV)相关死亡率以及CV事件发生率。采用多变量Cox比例风险回归分析比较心率<60、60 - 79以及≥101次/分钟患者的全因死亡率与心率80 - 100次/分钟患者的全因死亡率。此外,我们比较了首次透析 session 时未使用β受体阻滞剂或无心力衰竭症状患者的结局。
四组患者的全因死亡率存在显著差异(P = 0.007)。多变量分析显示,心率≥101次/分钟患者的全因死亡率显著高于心率80 - 100次/分钟患者(风险比[HR] = 2.30,95%置信区间[CI]:1.25 - 4.23)。亚组分析表明,在未使用β受体阻滞剂或无心力衰竭症状的患者中,心率≥101次/分钟患者的全因死亡率显著高于心率80 - 100次/分钟患者(HR分别为2.98,95% CI:1.51 - 5.88;HR = 3.65,95% CI:1.59 - 8.36)。
