Heart failure (HF) results in high hospitalization rates and healthcare costs. Telemonitoring of HF has been shown to result in improved outcomes but usually involves the use of expensive equipment. A more feasible alternative may be the use of a Web site. The purpose of this study is to investigate the use of a Web site designed for HF telemonitoring. Patients newly referred to a heart function clinic were screened for eligibility. Twenty participants were recruited and entered their weight and symptoms onto the Web site for 6 months. A nurse monitored the Web site for changes in participant health status and telephoned the participants as necessary. Self-care, quality of life, 6-minute walk test, and N-terminal prohormone brain natriuretic peptide (NT-proBNP) were assessed. Interviews were conducted to assess intervention uptake. Seventeen participants completed the study. A significant change was observed on the maintenance subscale of the Self-Care of Heart Failure Index (p = 0.039). There was a trend toward improvement on the confidence subscale of the Self-Care of Heart Failure Index (p = 0.069), Minnesota Living With Heart Failure((R)) Questionnaire (p = 0.337), 6-minute walk test (p = 0.124), and NT-proBNP (p = 0.210). Participants and nurses demonstrated a favorable uptake of the Web site. A Web site that facilitates the telemonitoring of patients with HF was favorably accepted and its use in this pilot study was associated with improved self-care skills. However, further investigation is warranted in a larger study population.
心力衰竭（HF）导致高住院率和医疗保健成本。远程监测 HF 已被证明可改善预后，但通常涉及使用昂贵的设备。更可行的替代方法可能是使用网站。本研究旨在探讨用于 HF 远程监测的网站的使用。对新转至心脏功能诊所的患者进行了资格筛选。招募了 20 名参与者，并在 6 个月的时间内在网站上输入了他们的体重和症状。护士监测网站上参与者健康状况的变化，并在必要时致电给参与者。评估了自我护理、生活质量、6 分钟步行测试和 N 末端脑利钠肽前体（NT-proBNP）。进行了访谈以评估干预措施的采用情况。有 17 名参与者完成了研究。在心力衰竭自我护理指数（HFCI）的维持子量表上观察到显著变化（p = 0.039）。HFCI 的信心子量表、明尼苏达州心力衰竭生活质量量表（MLHFQ）、6 分钟步行测试和 NT-proBNP 均有改善趋势（p = 0.069、0.337、0.124 和 0.210）。参与者和护士对该网站的接受度很高。一个促进 HF 患者远程监测的网站得到了很好的认可，在这项初步研究中，它的使用与改善自我护理技能有关。但是，在更大的研究人群中还需要进一步的调查。
