Abstract [en]
Background Type D personality refers to a combination of simultaneously high levels of negative affectivity and social inhibition. The present study aimed to examine whether type D personality was independently associated with recurrent myocardial infarction or all-cause mortality in post-acute myocardial infarction patients, using any of the previously proposed methods for measuring type D personality. Design This was a prospective cohort study. Methods Utilising data from the Västmanland Myocardial Infarction Study, 946 post-acute myocardial infarction patients having data on the DS14 instrument used to measure type D personality were followed-up for recurrent myocardial infarction and all-cause mortality until 9 December 2015. Data were analysed using Cox regression, adjusted for established risk factors. Results In total, 133 (14.1%) patients suffered from type D personality. During a mean follow-up time for recurrent myocardial infarction of 5.7 (3.2) years, 166 (17.5%) patients were affected by recurrent myocardial infarction, of which 26 (15.7%) had type D personality, while during a mean follow-up time for all-cause mortality of 6.3 (2.9) years, 321 (33.9%) patients died, of which 42 (13.1%) had type D personality. After adjusting for established risk factors, type D personality was not significantly associated with recurrent myocardial infarction or all-cause mortality using any of the previously proposed methods for measuring type D personality. A weak association was found between the social inhibition part of type D personality and a decreased risk of all-cause mortality, but this association was not significant after taking missing data into account in a multiple imputation analysis. Conclusions No support was found for type D personality being independently associated with recurrent myocardial infarction or all-cause mortality in post-acute myocardial infarction patients, using any of the previously proposed methods for measuring type D personality.
