Abstract
Background Type D personality, described as a consistent tendency to experience increased levels of social inhibition and negative affectivity, has a robust association with negative outcomes following myocardial infarction (MI). However, little is known about its determinants in our setting. Our aim was to assess the prevalence and correlates of Type D personality among survivors following acute MI (AMI). Methods Two hundred participants with AMI were recruited over an 18-month period. Type D scale-14 was used to evaluate the presence of Type D personality. Apart from sociodemographic factors, depression, anxiety, stress, coping, personality, quality of life, and perceived social support were assessed using standard measures. Results Type D personality was present in 24% of samples ( n = 48). In multivariate Poisson regression analysis, younger age (prevalence ratio [PR]: 0.950, 95% confidence intervals [CIs]: 0.927-0.974), high depression (PR: 1.372, 95% CI: 1.216-1.548), and low family support (PR: 0.898, 95% CI: 0.849-0.949) emerged as independent predictors of Type D personality in participants with AMI. Conclusion Type D personality is seen in a significant proportion of AMI, consistent with global literature. Our findings suggest that among Indian patients with AMI, the presence or absence of Type D personality may represent two distinct subpopulations.
