摘要
目的探讨运用6 min步行试验(6MWT)对慢性心力衰竭(CHF)稳定期患者制订最佳有氧运动方案。方法选取2021年6月至2022年6月南昌大学第二附属医院收治的100例CHF稳定期患者为研究对象,采用随机数字表法分为对照组和试验组,各50例。对照组实施自主运动,试验组运用6MWT制订最佳有氧运动方案,均连续干预6个月。比较两组患者的纽约心脏病协会(NYHA)心功能分级、6MWT距离、B型脑利尿钠肽(BNP)水平、自感劳累程度(Borg评分)、负性情绪[广泛性焦虑障碍量表(GAD-7)、综合医院健康问卷抑郁量表-9(PHQ-9)]和生活质量[明尼苏达心力衰竭生活质量问卷表(MLHFQ)]。结果两组患者干预前的NYHA心功能分级比较,差异无统计学意义(P>0.05);试验组干预后的NYHA心功能分级优于对照组,差异有统计学意义(P<0.05)。两组干预前的6MWT距离、BNP水平比较,差异无统计学意义(P>0.05);试验组干预后的6MWT长于对照组,BNP水平低于对照组,差异有统计学意义(P<0.05)。两组干预前的Borg评分、GAD-7、PHQ-9和MLHFQ评分比较,差异无统计学意义(P>0.05);试验组干预后的Borg、GAD-7、PHQ-9、MLHFQ评分低于对照组,差异有统计学意义(P<0.05)。结论运用6MWT可为CHF稳定期患者制订最佳有氧运动方案,改善心功能、心衰症状及负性情绪,降低BNP水平,提升患者生活质量,是一种理想的干预方式。
Objective To investigate the optimal aerobic exercise scheme for patients with chronic heart failure(CHF)in stable stage by using 6 min walking test(6MWT).Methods A total of 100 CHF patients admitted to the Second Affiliated Hospital of Nanchang University from June 2021 to June 2022 were selected as the study objects,and were divided into control group and experimental group by random number table method,with 50 cases in each group.The control group performed independent exercise,and the experimental group developed the optimal aerobic exercise program using 6MWT.The intervention was continuous for 6 months.New York Heart Association(NYHA)cardiac function rating,6MWT distance,B-type natriuretic peptide(BNP)levels,perceived fatigue(Borg score),negative mood(generalized anxiety disorder 7-item scale[GAD-7],patient health questionnaire-9[PHQ-9])and quality of life(Minnesota living with heart failure questionnaire[MLHFQ])were compared between the two groups.Results There was no significant difference in NYHA cardiac function classification between the two groups before intervention(P>0.05).The NYHA cardiac function grade of experimental group after intervention was better than that of control group,and the difference was statistically significant(P<0.05).There were no significant differences in 6MWT distance and BNP level between the two groups before intervention(P>0.05).After intervention,the 6MWT of experimental group was longer than that of control group,and BNP level was lower than that of control group,the differences were statistically significant(P<0.05).There were no significant differences in Borg scores,GAD-7,PHQ-9 and MLHFQ scores between the two groups before intervention(P>0.05).The Borg,GAD-7,PHQ-9 and MLHFQ scores of experimental groups were lower than those of control group after intervention,and the differences were statistically significant(P<0.05).Conclusion The application of 6MWT can establish the best aerobic exercise program for CHF patients in stable stage,improve heart function,heart failur
