The Efficacy of Double-Heart Nursing in Combination with Seaweed Polysaccharide for Patients with Coronary Heart Disease Complicated with Diabetes: A Pilot, Randomized Clinical Trial

OBJECTIVE: To study and explore the effect of double-heart nursing combined with seaweed polysaccharide on improving the self-efficacy and quality of life of patients with coronary heart disease and diabetes. METHODS: Eligible 214 patients with coronary heart disease and diabetes who were diagnosed and treated in our hospital between year 2017 and 2020 were randomized at a ratio of 1 : 1 to either control group (seaweed polysaccharide) or observation group (double-heart nursing combined with seaweed polysaccharide). The self-efficacy and quality of life of the two groups of patients after treatment were compared. RESULTS: The observation group reported a lower blood glucose level after treatment vs. the control group [(6.28 ± 4.49/8.24 ± 2.01) vs. (7.74 ± 4.18/11.41 ± 3.12)] (p < 0.05); a lower incidence of lesions in the observation group versus the control group after treatment (p < 0.05); and significantly lower SAS and SDS scores of the observation group vs. the control group was observed [(41.27 ± 4.08/43.81 ± 2.93) vs. (62.74 ± 3.48/61.58 ± 3.85)] (p < 0.05). Regarding the self-efficacy, the observation group was superior to the control group after treatment (p < 0.05). The treatment with double-heart nursing combined with seaweed polysaccharide was associated with the improvement of the quality of life with respect to social function, psychological function, and material life (each p < 0.05). The observation obtained a significantly higher satisfaction rate in comparison with the control group [107 (98.13%) vs.95 (88.80%)] (p < 0.05). CONCLUSION: Seaweed polysaccharide and double-heart nursing might be practical in improving the self-efficacy and quality of life of patients with coronary heart disease and diabetes mellitus, compared with conventional clinical treatment alone.
