目的：探究健康管理网络平台对心肌梗死后心力衰竭患者预后的干预研究，旨在改善心力衰竭患者的生存质量。方法：纳入青岛大学附属医院急诊内科2018年12月至2019年12月份收治的急性心肌梗死并发心力衰竭的214名患者作为研究对象，按照随机数表法，将其分为对照组(n = 107)和研究组(n = 107)；对照组为常规治疗后门诊随访，研究组为在常规治疗基础上通过健康管理网络平台加强患者用药指导及健康教育指导。比较2组患者在干预前后血浆中NT-pro BNP、6分钟步行距离(6MWD)、左室射血分数(LVEF)、左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)及患者再住院率。结果：对比两组患者干预前的血浆NT-pro BNP、6分钟步行距离(6MWD)、左室射血分数(LVEF)、左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)，差异无统计学意义(P > 0.05)。干预治疗后研究组各项指标均显著优于对照组，差异具有统计学意义(P < 0.05)。研究组再住院率低于对照组，但无显著性差异(P > 0.05)。结论：通过健康管理网络平台对出院患者的干预指导，能够改善患者的心功能，提高患者生活质量，改善预后，降低患者再住院率。
Objective: To explore the intervention of health management network platform on the prognosis of patients with heart failure after myocardial infarction in order to improve the quality of life of patients with heart failure. Methods: 214 patients with acute myocardial infarction complicated with heart failure admitted to the Emergency Department of The Affiliated Hospital of Qingdao University from December 2018 to December 2019 were enrolled as study subjects, and were divided into control group (n = 107) and study group (n = 107) according to the random number table method. The control group received outpatient follow-up after routine treatment, and the study group strengthened medication guidance and health education guidance for patients through the health management network platform on the basis of routine treatment. Plasma NT-proBNP, 6-minute walking distance (6MWD), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), and patient rehospitalization rates were compared between the two groups before and after intervention. Results: after 12 months of intervention, plasma NT-proBNP, 6-minute walking distance (6MWD), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), and left ventricular end-systolic diameter (LVESD) were compared between the two groups before intervention, showing no statistically significant differences (P > 0.05). After intervention treatment, all indexes of the study group were significantly better than those of the control group, and the difference was statistically significant (P < 0.05). The rehospitalization rate of the study group was lower than that of the control group, but there was no significant difference (P > 0.05). Conclusion: The intervention and guidance of the health management network platform for discharged patients can improve the cardiac function, improve the quality of life, improve the prognosis and
