Abstract:

Objective To evaluate the application effect of a phased health achievement intervention program in elderly patients with diabetic cardiomyopathy（DCM）. Methods A prospective，intention-to-treat，randomized controlled clinical trial was conducted in an independent medical institution. Elderly patients with DCM who treated at the First Affiliated Hospital of Zhengzhou University from April 2022 to August 2023 were independently recruited as the study subjects. They were randomly divided into an experimental group（n=45） and a control group（n=45） using computer-based simple randomization. The control group received routine nursing in cardiology department. While the experimental group received the phased health achievement intervention. Both groups were intervented for 3 months. Before nursing intervention and at the end of the third month，the blood glucose control [HbA1c，fasting blood glucose（FBG），postprandial blood glucose variability coefficient（CV）]，heart function improvement[left ventricular ejection fraction（LVEF），cTnT]，and self-management ability[Diabetes Self-Management（DSM）] were compared between the two groups. Results Ultimately，42 cases were included in the experimental group and 41 cases in the control group. At the end of the 3rd month of nursing intervention，HbA1c，FBG，CV，and cTnT in the experimental group were all lower than those in the control group（P<0.05），and the LVEF index and DSM scale score were higher than those in the control group（P<0.05）. Conclusion The phased health achievement intervention program can significantly improve blood glucose and cardiac function in elderly patients with DCM，enhance the quality of life and self-management ability of the prognosis，and provide a scientific basis for formulating more effective individualized health management strategies.
