心脏康复训练对慢性心衰患者运动耐力及心脏功能的影响

Effects of Cardiac Rehabilitation Training on Exercise Endurance and Cardiac Function in Patients with Chronic Heart Failure

目的探讨心脏康复训练对慢性心衰患者运动耐力及心脏功能的影响。方法方便选取该院2019年1—12月收治的80例慢性心衰的患者为研究对象,采用信封法随机分为观察组40例和对照组40例。对照组采用常规药物治疗+康复指导,观察组在对照组的基础上进行心脏康复训练。比较两组干预前后心脏功能、血浆氨基末端脑钠肽前体(NT-proBNP)、6 min步行距离及生活质量的变化。结果观察组干预后左室射血分数(LVEF)(48.56±3.71)%大于对照组的(40.94±4.37)%,左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)分别为(53.28±4.12)mm、(42.45±5.49)mm小于对照组的(59.73±4.75)mm、(48.32±4.62)mm,差异有统计学意义(t=8.407、6.488、13.988,P<0.001)。观察组干预后的NT-proBNP为(710.34±146.83)pg/mL低于对照组的(946.18±195.15)pg/mL,6 min步行距离(315.48±54.54)m长于对照组的(285.42±47.61)m,明尼苏达心功能不全生命质量量表(MLHFQ)评分(45.45±6.82)分低于对照组的(56.48±7.63)分,差异有统计学意义(t=6.108、2.626、6.817,P<0.05)。结论心脏康复训练能够进一步改善慢性心衰患者的心脏功能,增强患者的运动耐力,提升患者的生活质量。

Objective To investigate the effect of cardiac rehabilitation training on exercise endurance and cardiac function in patients with chronic heart failure.Methods A total of 80 patients with chronic heart failure admitted to the hospital from January to December 2019 were convenient selected as the research objects,and the envelope method was used to randomly divide them into an observation group of 40 cases and a control group of 40 cases.The control group received conventional medication+rehabilitation guidance,and the observation group received cardiac rehabilitation training on the basis of the control group.The changes in cardiac function,plasma N-terminal pro-brain natriuretic peptide(NT-proBNP),6-min walking distance and quality of life before and after intervention were compared between the two groups.Results After intervention,the left ventricular ejection fraction(LVEF)(48.56±3.71)%of the observation group was greater than(40.94±4.37)%of the control group.The left ventricular end diastolic diameter(LVEDD)and left ventricular end systolic diameter(LVESD)were(53.28±4.12)mm and(42.45±5.49)mm,smaller than those of the control group(59.73±4.75)mm and(48.32±4.62)mm,the difference was statistically significant(t=8.407,6.488,13.988,P<0.001).The NT-proBNP of the observation group after intervention was(710.34±146.83)pg/mL lower than that of the control group(946.18±195.15)pg/mL,and the 6-min walking distance was(315.48±54.54)m longer than that of the control group(285.42±47.61)m,the Minnesota Cardiac Insufficiency Quality of Life Scale(MLHFQ)score(45.45±6.82)points was lower than the control group(56.48±7.63)points,the difference was statistically significant(t=6.108,2.626,6.817,P<0.05).Conclusion Cardiac rehabilitation training can further improve the cardiac function of patients with chronic heart failure,enhance their exercise endurance,and improve their quality of life.
