背景以前的几项研究支持下述假说:心力衰竭病人埋藏血流动力学监察系统可能减少住院。作者开展一项单盲临床试验进行评估。方法曾因心力衰竭住院的NYHAⅢ级心力衰竭病人(不论射血分数高、低),选入美国的64个中心,随机分入集中电子系统,用一无线埋藏血流动力学监察系统(VV-IHN,治疗组)或对照组,至少6个月。病人不知其组别。除标准治疗外,治疗组每日测肺动脉压,对照组仅接受标准治疗。第一终点为6个月的心力衰竭-相关住院。6个月时安全性终点为无仪器-相关的
Background Several previous studies supported the hypothesis that buried hemodynamic monitoring systems in patients with heart failure may reduce hospitalization. The authors conducted a single blind clinical trial to assess. Methods Sixty-four centers in the United States were enrolled in NYHA class III heart failure hospitalized with heart failure (irrespective of the high and low ejection fraction). The patients were randomized to a centralized electronic system with a wireless ambulatory hemodynamic monitoring system (VV- IHN, treatment group) or control group for at least 6 months. Patients do not know their group. In addition to standard treatment, the treatment group daily test pulmonary artery pressure, the control group received only standard treatment. The first endpoint was 6 months of heart failure - related hospitalizations. The safety end point at 6 months was instrumentless-related
