Digoxin use in patients with heart failure with reduced ejection fraction (HFrEF) and sinus rhythm remains controversial. We aimed to assess the prognostic impact of digoxin in patients in sinus rhythm submitted to cardiac resynchronization therapy (CRT).Retrospective study including 297 consecutive patients in sinus rhythm, with advanced HFrEF submitted to CRT. Patients were divided into two groups - with digoxin (DG) and without digoxin (NDG). During a mean follow-up of 4.9 ± 3.4 years we evaluated the impact of digoxin on the composite endpoint defined as cardiovascular hospitalization, progression to heart transplantation and all-cause mortality.Previous to CRT, 104 patients (35%) were chronically under digoxin and 193 patients (65%) without digoxin treatment. The 2 groups did not differ significantly regarding HF functional class, HF aetiology, QRS and baseline left ventricular ejection fraction (LVEF). The proportion of responders to CRT was similar in both groups (54% in DG vs 56% in NDG, p=0.78). During the long term follow up period, the primary endpoint occurred in a higher proportion in DG patients (67 vs 48%, p=0.002). After adjustment for potential confounders, digoxin use remained as an independent predictor of the composite endpoint of CV hospitalization, heart transplantation and all-cause mortality (HR = 1.58, CI 95 [1.01 - 2.46], p = 0.045).In conclusion, in patients in sinus rhythm with HFrEF submitted to CRT, digoxin use was associated to CV hospitalization, progression to heart transplant and all-cause mortality.

接受心脏再同步治疗的晚期心力衰竭和窦性心律患者的地高辛——有什么好处吗?

在射血分数降低(HFrEF)和窦性心律的心力衰竭患者中使用地高辛仍存在争议。我们旨在评估地高辛对接受心脏再同步化治疗 (CRT) 的窦性心律患者的预后影响。回顾性研究包括 297 名接受 CRT 的晚期 HFrEF 的窦性心律患者。患者被分为两组 - 使用地高辛 (DG) 和不使用地高辛 (NDG)。在 4.9 ± 3.4 年的平均随访期间,我们评估了地高辛对复合终点(定义为心血管住院、心脏移植进展和全因死亡率)的影响。在 CRT 之前,104 名患者(35%)长期服用地高辛193 名患者 (65%) 未接受地高辛治疗。两组在 HF 功能类别方面没有显着差异,HF 病因、QRS 和基线左心室射血分数 (LVEF)。两组对 CRT 的反应者比例相似(DG 为 54%,NDG 为 56%,p=0.78)。在长期随访期间,主要终点发生在 DG 患者中的比例较高(67% vs 48%,p=0.002)。在调整了潜在的混杂因素后,地高辛的使用仍然是心血管住院、心脏移植和全因死亡率复合终点的独立预测因子(HR = 1.58,CI 95 [1.01 - 2.46],p = 0.045)。 总之,在在接受 CRT 治疗的 HFrEF 的窦性心律患者中,使用地高辛与心血管住院、心脏移植进展和全因死亡率相关。两组对 CRT 的反应者比例相似(DG 为 54%,NDG 为 56%,p=0.78)。在长期随访期间,主要终点发生在 DG 患者中的比例较高(67% vs 48%,p=0.002)。在调整了潜在的混杂因素后,地高辛的使用仍然是心血管住院、心脏移植和全因死亡率复合终点的独立预测因子(HR = 1.58,CI 95 [1.01 - 2.46],p = 0.045)。 总之,在在接受 CRT 治疗的 HFrEF 的窦性心律患者中,使用地高辛与心血管住院、心脏移植进展和全因死亡率相关。两组对 CRT 的反应者比例相似(DG 为 54%,NDG 为 56%,p=0.78)。在长期随访期间,主要终点发生在 DG 患者中的比例更高(67% vs 48%,p=0.002)。在调整了潜在的混杂因素后,地高辛的使用仍然是心血管住院、心脏移植和全因死亡率复合终点的独立预测因子(HR = 1.58,CI 95 [1.01 - 2.46],p = 0.045)。 总之,在在接受 CRT 治疗的 HFrEF 的窦性心律患者中,使用地高辛与心血管住院、心脏移植进展和全因死亡率相关。
