Abstract:
Objective:To explore the characteristics of attention bias in patients with type D personality coronary heart disease (CHD), and provide a new theoretical perspective for elucidating the effect of type D personality on the pathogenesis of CHD and formulating prevention strategies.Methods:From March 2021 to September 2021, a total of 40 CHD patients who were hospitalized in the 2nd Affiliated Hospital of Harbin Medical University were enrolled using the convenient sampling method and event-related potential (ERP). Patients were divided into the type D personality group and the non-type D personality group by Type D Personality Scale-14, and matched according to age, gender and years of education. The Self-Rating Depression Scale was used to exclude patients with depression. The Negative Cognitive Processing Bias Questionnaire (NCPBQ) was used to measure negative cognitive processing bias. Dot-probe task and ERP technology were used to analyze the characteristics of attention bias, with the emotional face images as experimental stimulation materials.Results:A total of 15 CHD patients with type D personality and 15 CHD patients without type D personality were enrolled. The scores of NCPBQ and negative rumination bias dimension of CHD patients with type D personality were higher than those of CHD patients without type D personality, and the differences were statistically significant ( P<0.05). Behavioral experiments data showed that CHD patients without type D personality had a shorter response time to positive face images than negative face images in inconsistent conditional stimulation ( F=10.646, P<0.05), CHD patients without type D personality had a shorter response time to negative face images in consistent prompt type than inconsistent prompt type ( F=4.744, P<0.05). ERP experimental data showed that CHD patients with type D personality has higher N1 amplitude facing negative and positive face images stimulation ( F=8.973, P<0.05), CHD patients without type D personality had higher P3 amplitude facing positive face images stimulation ( F=6.750, P<0.05) . Conclusions:CHD patients with type D personality patients have negative cognitive processing bias, and they are more sensitive to emotional stimulation, invest more attention in the early stage of cognitive process, and have difficulty in disengaging attention from negative stimulation. Clinical medical staff should reduce negative stimulation and carry out positive psychological intervention in CHD patients with type D personality to reduce the adverse effects of negative stimulation on the prognosis of patients.
