Abstract:
Objective:To explore the effects of type D personality on mild cognitive dysfunction (MCI) in patients with coronary heart disease and the multiple mediating roles of dietary inflammation index (DII) and systemic immune inflammation index (SII) between type D personality and MCI.Methods:A cross-sectional study was used. A total of 321 patients diagnosed with coronary heart disease by coronary angiography in the Second Affiliated Hospital of Harbin Medical University from May 2022 to March 2023 were selected as the study objects by convenient sampling method. General Information Questionnaire, Type-D Personality Scale-14, Montreal Cognitive Assessment, and Semi-Quantitative Food Frequency Questionnaire were employed for data collection. DII and SII were used to evaluate dietary inflammatory potential and systemic inflammatory status, respectively. Structural equation modeling was utilized to analyze the mediating effectsamong type D personality, DII, SII and MCI.Results:A total of 306 valid questionnaires were collected. Among the 306 patients, there were 215 males (70.3%) and 91 females (29.7%), aged 27-70 (59.24 ± 9.16) years old. The structural equation model showed that type D personality could directly influence MCI (effect size = - 1.098, 95% CI - 1.869 - - 0.327), and could also mediate the occurrence of MCI in coronary heart disease patients through the single mediation of DII (effect size = - 0.374, 95% CI - 0.644 - - 0.128) and SII (effect size = - 0.450, 95% CI - 0.806 - - 0.132), as well as the chain mediation of DII and SII (effect size = - 0.146, 95% CI - 0.293 - - 0.027). Conclusions:Type D personality, DII and SII can affect the occurrence of MCI in CHD patients, and DII and SII play multiple mediating roles between type D personality and MCI in patients with coronary heart disease. Clinical and community nurses can improve the unhealthy dietary behavior, reduce the level of inflammation and delay the occurrence and development of MCI by early screening of type D personality in patients with coronary heart disease.
