Abstract:

Objective　To observe the effect of dual heart care model intervention on self-efficacy in patients with heart failure. Methods　A total of 96 patients with heart failure admitted to Department of Cardiovascular Medicine, Dongguan Liaobu Hospital from June 2021 to December 2022 were randomly divided into a control group and a study group, with 48 patients in each group. The control group included 28 males and 20 females, aged (68.81±4.12) years. The study group included 26 males and 22 females, aged (68.34±4.35) years. The control group received routine care for heart failure, and the study group received dual-heart care model intervention based on routine care, including emotional care and behavioral intervention. The cardiac function, psychological state, self-efficacy, daily living ability, and complications were compared between the two groups before and after nursing. Independent sample t test and χ² test were used as statistical methods. Results　After 6 months of nursing, the left ventricular ejection fraction (LVEF) and 6-minute walking distance (6MWD) of the study group were higher than those of the control group [(46.22±5.35)% vs. (43.71±5.63)%, (268.85±25.51) m vs. (253.44±23.68) m], the left ventricular end-systolic diameter (LVESD), Self-Rating Anxiety Scale score, and Self-Rating Depression Scale score were lower than those of the control group [(32.21±2.22) mm vs. (33.56±2.13) mm, (38.66±4.59) points vs. (41.28±4.75) points, (39.25±4.60) points vs. (41.93±4.87) points], and the scores of Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) were higher than those of the control group [(34.18±2.64) points vs. (32.83±2.57) points, (53.11±3.52) points vs. (51.35±3.61) points], with statistically significant differences (t=2.239, 3.067, 3.040, 2.748, 2.772, 2.539, and 2.418, all P<0.05). The proportion of self-confidence of the General Self Efficacy Scale (GSES) in the study group was higher than that in the control group [83.33% (40/48) vs. 62.50% (30/48)] (χ²=5.275, P=0.022). There was no statistically significant difference in the incidence of complications between the two groups [2.08% (1/48) vs. 8.33% (4/48)] (χ²=1.899, P=0.168). Conclusion　Dual-heart care model intervention can promote the improvement of heart function in patients with heart failure to some extent, delay the disease progression, improve the psychological status, and enhance their self-efficacy and daily living ability.

摘要：

目的　观察双心护理模式干预对心力衰竭患者心功能及自我效能的影响。方法　选取2021年6月至2022年12月东莞市寮步医院心血管内科收治的心力衰竭患者96例，随机分为对照组和研究组，各48例。对照组男28例，女20例，年龄（68.81±4.12）岁；研究组男26例，女22例，年龄（68.34±4.35）岁。对照组采用心力衰竭常规护理，研究组则在常规护理的基础上增加双心护理模式干预，包括情感护理、行为干预。比较两组护理前后的心功能、心理状态、自我效能感、日常生活能力、并发症。统计学方法采用独立样本t检验、χ²检验。结果　护理6个月后，研究组的左心室射血分数（LVEF）、6分钟步行距离（6MWD）均高于对照组［（46.22±5.35）%比（43.71±5.63）%、（268.85±25.51）m比（253.44±23.68）m］，左心室收缩末期内径（LVESD）、焦虑自评量表评分、抑郁自评量表评分均低于对照组［（32.21±2.22）mm比（33.56±2.13）mm、（38.66±4.59）分比（41.28±4.75）分、（39.25±4.60）分比（41.93±4.87）分］，基本日常生活活动能力（BADL）、工具性日常生活活动能力（IADL）评分均高于对照组［（34.18±2.64）分比（32.83±2.57）分、（53.11±3.52）分比（51.35±3.61）分］，差异均有统计学意义（t=2.239、3.067、3.040、2.748、2.772、2.539、2.418，均P<0.05）；研究组一般自我效能感量表（GSES）自信占比高于对照组［83.33%（40/48）比62.50%（30/48）］（χ²=5.275，P=0.022）。两组护理期间并发症发生率比较差异无统计学意义［2.08%（1/48）比8.33%（4/48）］（χ²=1.899，P=0.168）。结论　双心护理模式干预可在一定程度上促进心力衰竭患者的心功能改善，延缓疾病进展，改善心理状态，提高患者自我效能与日常生活能力。
