End-stage heart failure (ESHF) is characterized by severe cardiac dysfunction with persistent disabling symptoms and recurrent acute decompensated heart failure (ADHF), despite guideline-directed medical therapy. The aim of this study was to evaluate the efficacy and safety of intravenous diuretics administration at home through a peripherally inserted central venous catheter (PICC) in ESHF patients.
Forty-one ESHF patients received PICC implantation for intravenous diuretic administration at home. The primary efficacy endpoint was the patient-level number of HF hospitalizations in the short (1-3 months), medium (six months), and long term (1 year), before and after PICC implantation. Pre- and post-PICC ADHF-free days were also evaluated as co-primary endpoint. Secondary endpoints comprised changes in clinical, laboratory and echocardiographic parameters, and device safety. A cost-effectiveness analysis was performed to estimate the economic impact of using PICC. For each time frame analyzed, a significant reduction in the number of hospitalizations due to ADHF was observed, resulting in a significant increase in ADHF-free days (71 ± 44 vs. 163 ± 136, p = 0.003). In matched patients' analysis, significant decrease in body weight (68 ± 16 kg vs. 63 ± 10 kg, p = 0.041) and mitral regurgitation grade 3/4 (55% vs. 18%, p < 0.001) were also observed. Freedom from PICC-related complications was observed in 61% of patients. A significant reduction in overall ADHF-hospitalizations cost was observed.
This proof-of-concept study demonstrates the effectiveness and safety of home administration of intravenous diuretic therapy via PICC in ESHF patients. This palliative cost-effective strategy can be taken in consideration for selected end-stage patients no longer responsive to conventional therapies.
终末期心力衰竭(ESHF)的特征是严重的心脏功能障碍,尽管遵循了指南指导的药物治疗,但仍持续存在致残症状和反复发作的急性失代偿性心力衰竭(ADHF)。本研究的目的是评估通过外周插入的中心静脉导管(PICC)在家中给予静脉利尿剂在 ESHF 患者中的疗效和安全性。
41 例 ESHF 患者接受 PICC 植入术,在家中进行静脉利尿剂治疗。主要疗效终点是患者在 PICC 植入前后短期(1-3 个月)、中期(6 个月)和长期(1 年)因 HF 住院的次数。还评估了 PICC 植入前后 ADHF 无天数作为共同主要终点。次要终点包括临床、实验室和超声心动图参数的变化以及设备安全性。进行了成本效益分析以估计使用 PICC 的经济影响。在分析的每个时间段,ADHF 导致的住院人数都显著减少,导致 ADHF 无天数显著增加(71±44 天 vs. 163±136 天,p=0.003)。在匹配患者的分析中,还观察到体重显著下降(68±16 公斤 vs. 63±10 公斤,p=0.041)和二尖瓣反流 3/4 级(55% vs. 18%,p<0.001)。61%的患者未发生与 PICC 相关的并发症。观察到整体 ADHF 住院费用显著降低。
这项概念验证研究表明,在 ESHF 患者中通过 PICC 在家中给予静脉利尿剂治疗是有效和安全的。对于不再对常规治疗有反应的选定终末期患者,这种姑息性、具有成本效益的策略可以考虑。
