the role of type d personality in acute coronary syndrome

Introduction: acute coronary syndrome (acs) is one of the most common causes of death in patients with cardiovascular diseases (cvd). in addition to the known physical factors influencing the incidence of cvd, some psychologists have pointed to the role of psychological factors such as personality type.objective: this study aimed to determine the role of type d personality in acs patients in iran in 2019.materials and methods: in a case-control study, 112 participants were included. a total of 56 patients with acs were compared with 56 matched people without acs. they were selected by the convenience sampling method. type d scale 14 (ds14) was used to assess the type d personality. the chi-squared test, independent t-test, and multivariate logistic regression were used to analyze the obtained data.results: the mean±sd age in the case group was 57.23±8.562 years, and in the mean±sd age in the control group was 57.25±8.529 years. also, most participants in both groups were men (71.4%). the result showed that type d personality was more prevalent in patients with acs (26% vs 7.1%; p=0.006). based on multivariate regression analysis and after controlling for demographic and clinical risk factors, type d personality was independently associated with acs (or=5.323, 95% ci; 0.987-28/712, p=0.052). also, after investigating subscales, only social inhibition had a significant association with acs (p=0.008).conclusion: type d personality is an independent risk factor of the acs. thus, type d personality may make people vulnerable to the acs. therefore, besides medical interventions, clinicians must consider behavioral interventions to reduce the incidence of acs.
