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.
