目的 探讨家庭医疗服务对慢性心衰患者预后生存质量的影响。方法 选取90例慢性心力衰竭患者作为研究对象，干预组采用家庭医疗服务模式。采用Lee氏心衰积分对患者干预后心衰疗效进行评估。应用心肺运动实验和6分钟步行测试（6MWT）评估患者的心功能状态。评估营养状况、生活质量和再入院率。结果 经干预后干预组患者的pVO2、% pVO2和VO2无氧阈值显著高于对照组（P<0.05）。干预组患者的MNA评分、Hb和ALB水平显著高于对照组。干预组患者的心衰再入院率显著低于对照组。结论 家庭医疗服务模式应用于慢性心衰患者的管理，能显著改善患者的营养状况，改善患者心衰症状和心肺运动功能。

Objective To study the effect of family medical services on the prognosis and quality of life of patients with chronic heart failure. MethodsA total of 90 patients with chronic heart failure were randomly divided into 45 patients in the control group and 45 patients in the intervention group. patients in the control group received routine medical services and regular health education, and the intervention group adopted a family medical service model. lee’s heart failure score was used to evaluate the efficacy of the patient ’ s heart failure before and after intervention. a cardiopulmonary exercise test and a 6-minute walking test (6MWT) were used to assess the patient’s cardiac function status. The changes of MNA, Hb and ALB were compared before and after intervention. The quality of life of the patient was assessed using a quality of life visual simulation score (VAS) scale and a sinhua minnesota heart failure quality of life score (MLHFQ). The readmission rates of the two groups were compared.ResultsAfter intervention, the heart failure score of the patients in the intervention group was significantly lower than that in the control group. The anaerobic thresholds of pVO2,% pVO2 and VO2 were significantly higher in the observation group(P<0.05) .The levels of MNA, Hb and ALB in the intervention group were significantly higher than those in the control group (P < 0.05).The 6MWT and VAS scores of the patients in the intervention group were significantly higher than those in the control group, and the MLHFQ scores were significantly lower than those in the control group(P<0.05). The readmission rate of patients with heart failure in the intervention group was significantly lower than that in the control group. Conclusions The application of family medical service mode to the management of patients with chronic heart failure can significantly improve the symptoms of heart failure and cardiopulmonary motor function, improve the quality of life, and reduce the re-hospitalization rate of heart failure.
