LIFE QUALITY OF MYOCARDIAL INFARCTION PATIENTS ACCORDING TO THE PRESENCE OF TYPE D PERSONALITY

Abstract

Introduction. Type D personality, or distress personality, i. e., a combination of negative affectivity and social inhibition, as well as poor life quality, are considered the predictors of cardiovascular morbidity and mortality. However, there is insufficient data on the role of Type D personality as a determinant of life quality in myocardial infarction patients. Aim is to assess the Q-positive myocardial infarction patients’ life quality and its association with Type D personality. Materials and Methods. The study included 158 patients aged 58.2±2.5 years, who were admitted to the hospital for ST-segment elevation myocardial infarction. ST-segment elevation myocardial infarction was diagnosed in accordance with the Clinical Guidelines of the Russian Society of Cardiology, 2020. Пациентам анализируемых групп проведено определение общеклинических параметров, психологическое тестирование с применением оценочных шкал тревоги и депрессии, опросников DS-14 и SF-36. Patients of the groups studied were tested for general clinical parameters and psychological characteristics using anxiety and depression rating scales, DS-14 and SF-36 questionnaires. Individuals with and without Type D personality were identified in the group of myocardial infarction patients. Results and Discussion. Type D personality was detected in 29.1% of myocardial infarction patients. In this group, an unfavorable psychological profile is noted: Their negative excitability, social suppression, depression, and personal/situational anxiety levels are higher than in the group without Type D personality. In patients with myocardial infarction and Type D personality, a lower quality of life and a decrease in the integral indicators of physical and psychologic components. Conclusions. Type D personality was proven to provide an adverse effect on the life quality in myocardial infarction patients. Cardiac rehabilitation programs should include interventions to reduce the Type D personality traits, especially social inhibition.
