Objectives: This study aimed to unveil the effect of depression death and anxiety death on coping style among coronary heart disease (CHD) patients in Tabriz, a city in the Northwest of Iran. Materials and Methods:In this cross-sectional study, 293 coronary heart disease patients were recruited from three hospitals in Tabriz from January to July 2015. Socio-demographic characteristics and CHD clinical history were archived by a checklist. Validated self-administered questionnaires were used to measure death depression, death anxiety, and coping style. The association between death depression and death anxiety with coping style was evaluated, using multivariable linear regression. Results:In this study, the participants were 60 ± 11 years of age. Death depression was most significantly influenced by occupation, and the death anxiety level was affected by the history of hospitalization with CHD. The coping style level was not statistically significant across sociodemographic and CHD clinical history characterises. In death depression, the third quartile was significantly and inversely associated with coping style, compared to reference category; β (95% CI); -1.60 (-2.97 to -0.27), P value = 0.02. Conclusions:Among CHD patients, death depression and death anxiety could be influenced by sociodemographic and CHD history background characteristics, respectively. Death depression could be considered as a determinant for coping style.
