(1) Background: Heart failure (HF) is a major cause of morbidity and mortality throughout the world. Despite substantial progress in its prevention and treatment, mortality rates remain high. Device therapy for HF mainly includes cardiac resynchronization therapy (CRT) and the use of an implantable cardioverter-defibrillator (ICD). Recently, however, a new device therapy-cardiac contractility modulation (CCM)-became available. (2) Aim: The purpose of this study is to present a first case-series of patients with different clinical patterns of HF with a reduced ejection fraction (HFrEF), supported with the newest generation of CCM devices. (3) Methods and results: Five patients with a left ventricular ejection fraction (LVEF) ≤ 35% and a New York Heart Association (NYHA) class ≥ III were supported with CCM OPTIMIZER SMART IPGCCMX10 at our clinic. The patients had a median age of 67 ± 8.03 years (47-80) and were all males-four with ischemic etiology dilated cardiomyopathy. In two cases, CCM was added on top of CRT (non-responders), and, in one patient, CCM was delivered during persistent atrial fibrillation (AF). After 6 months of follow-up, the LVEF increased from 25.4 ± 6.8% to 27 ± 9%, and the six-minute walk distance increased from 310 ± 65.1 m to 466 ± 23.6 m. One patient died 47 days after device implantation. (4) Conclusion: CCM therapy provided with the new model OPTIMIZER SMART IPG CCMX10 is safe, feasible, and applicable to a wide range of patients with HF.
(1) 背景:心力衰竭(HF)是全球发病和死亡的主要原因。尽管在其预防和治疗方面取得了重大进展,但死亡率仍然很高。心力衰竭的器械治疗主要包括心脏再同步治疗(CRT)和植入式心脏复律除颤器(ICD)的使用。然而,最近出现了一种新的器械治疗方法——心脏收缩力调制(CCM)。(2) 目的:本研究的目的是展示首例使用最新一代CCM设备支持的不同临床模式的射血分数降低的心力衰竭(HFrEF)患者的病例系列。(3) 方法和结果:在我们诊所,5例左心室射血分数(LVEF)≤35%且纽约心脏协会(NYHA)分级≥III级的患者接受了CCM OPTIMIZER SMART IPGCCMX10治疗。患者的中位年龄为67±8.03岁(47 - 80岁),均为男性,其中4例病因是缺血性扩张型心肌病。2例患者在CRT基础上加用了CCM(无反应者),1例患者在持续性心房颤动(AF)期间接受了CCM治疗。随访6个月后,LVEF从25.4±6.8%增加到27±9%,6分钟步行距离从310±65.1米增加到466±23.6米。1例患者在设备植入后47天死亡。(4) 结论:新型OPTIMIZER SMART IPG CCMX10提供的CCM治疗安全、可行,适用于广泛的心力衰竭患者。
