Abstract

Background: Data on the prognostic significance of pacing dependency in patients with cardiovascular implantable electronic devices (CIEDs) are sparse.

Methods: The prognostic significance of pacing dependency defined as absence of an intrinsic rhythm ≥ 30 bpm was determined in 786 patients with CIEDs at the authors' institution using univariate and multivariate regression analysis to identify predictors of all-cause mortality.

Results: During 49 months median follow-up, death occurred in 63 of 130 patients with pacing dependency compared to 241 of 656 patients without pacing dependency (48% versus 37%, hazard ratio [HR] 1.34; 95% confidence interval [CI]: 1.02-1.78, P = 0.04). Using multivariate regression analysis, predictors of all-cause mortality included age (HR 1.07; 95% CI: 1.05-1.08, P < 0.01), history of atrial fibrillation (HR 1.32, 95% CI: 1.03-1.69, P < 0.01), chronic kidney disease (HR 1.28; 95% CI: 1.00-1.63, P = 0.048) and New York Heart Association (NYHA) class ≥ III (HR 2.00; 95% CI: 1.52-2.62, P < 0.01), but not pacing dependency (HR 1.15; 95% CI: 0.86-1.54, P = 0.35).

Conclusions: In contrast to age, atrial fibrillation, chronic kidney disease and heart failure severity as indexed by NYHA functional class III or IV, pacing dependency does not appear to be an independent predictor of all-cause mortality in patients with CIEDs.

植入心血管电子设备的起搏依赖患者的预后。
背景:有关心血管植入式电子设备(CIED)患者起搏依赖性预后意义的数据很少:有关心血管植入式电子装置(CIED)患者起搏依赖性预后意义的数据很少:方法:采用单变量和多变量回归分析方法,对作者所在机构的786名心血管植入式电子装置患者进行了研究,确定了起搏依赖性的预后意义,起搏依赖性的定义是内在节律≥30 bpm的缺失,以确定全因死亡率的预测因素:在49个月的中位随访期间,130例起搏依赖患者中有63例死亡,而656例无起搏依赖患者中有241例死亡(48%对37%,危险比[HR]1.34;95%置信区间[CI]:1.02-1.78,P<0.05):1.02-1.78, P = 0.04).通过多变量回归分析,预测全因死亡率的因素包括年龄(HR 1.07;95% CI:1.05-1.08,P 结论:年龄与心房颤动相关性较低:与年龄、心房颤动、慢性肾病和以 NYHA 功能分级 III 或 IV 为指标的心衰严重程度相比,起搏依赖似乎不是 CIEDs 患者全因死亡率的独立预测因素。
