Abstract:

Objective To study the effects of type D personality on mortality of adults with congenital heart disease (CHD).Methods Two hundred and eighty seven adult patients with CHD admitted to the Department of Cardiovascular Medicine, the First Affiliated Hospital of University of Science and Technology of China from April 2016 to April 2020 were included in the study. Type D personality scale was applied to evaluate if the patients had Type D personality, the follow-up was ended in April 2021. The differences in general data and mortality of patients with type D personality and those without type D personality were further compared. Results A total of 263 patients were enrolled, 124 were male with average age of (49.4±7.1) years, 62 patients were found to have type D personality. Patients with type D personality were more likely to have NYHA II or higher cardiac function, and were more likely to have higher percentage for chronic kidney disease (12.9% vs 4.5%, P=0.039), unemployed status (32.3% vs 20.0%, P=0.043), and single (35.5% vs 20.1%, P=0.019). The patients with type D personality were found to have significantly worse survival than those without type D personality (82% vs 87%, P=0.014) at the end of the follow-up. Type D personality was noted to be significant predictor of death (hazard ratio of 1.85, 95% confidence interval 1.12-3.04, P=0.015) in Cox proportional hazard regression model analysis. Conclusion Type D personality is eligible to predict the mortality rate in adults with CHD, and need to pay attention to assessment in nursing work.
