Abstract

Objective: To explore the effect of chronic heart failure complicated with type 2 diabetes mellitus on cognitive function in the elderly.

Methods: 600 patients with chronic heart failure were selected from January 2018 to January 2021. All patients were divided into observation group (A) and control group (B). A was chronic heart failure complicated with type 2 diabetes mellitus group. B was chronic heart failure group. The clinical effects of the two groups were observed.

Results: Compared with the clinical indexes during and after operation, there were differences in operation time, postoperative recovery time, and treatment cost between A and B, but the difference is not significant (all P > 0.05). LVEF cardiac function index score, LVEF score of A compared with B, the difference was statistically significant (P < 0.05). The MMSE score and MoCA score of the two groups were compared. Before operation, the MMSE score and MoCA score of A were lower than those of B, and the difference was statistically significant (P < 0.05). After operation, the MMSE score and MoCA score in B were significantly higher than those in B, but the increasing trend of MMSE score and MoCA score in B was significantly higher than that in A (P < 0.05). Comparison of HAMA score and HAMD score: before operation, the HAMA score and HAMD score were higher in A, but the difference is not significant (P > 0.05). After operation, the scores of HAMA and HAMD in A and B decreased significantly, but the difference is not significant (P > 0.05). Multivariate analysis showed that the fasting blood glucose and glycosylated hemoglobin were the risk factors of cognitive impairment.

Conclusion: Type 2 diabetes mellitus in elderly patients with chronic heart failure will further aggravate cognitive impairment, and type 2 diabetes is an important independent risk factor affecting cognitive function, which accelerates cognitive impairment and significantly reduces the executive ability of elderly patients with chronic heart failure, resulting in a significant decline in patients' ability to understand and apply information.
