Abstract

Introduction: Smoking, anxiety and depression constitute predisposing factors of coronary artery disease.

Aim: The aim of this study was to investigate the degree of nicotine dependence in coronary patients and its relationship to anxiety and depression.

Methods: The study population consisted of 208 coronary patients, 131 men and 77 women, who were hospitalized in a hospital in Attica and were all smokers. The degree of nicotine dependence was measured by the Fagerstrom scale, while depression and anxiety intensity were assessed with the Zung SDS and SAS scales respectively.

Results: 158 participants (75.9%) were moderately to highly dependent on nicotine, 108 participants (51.9%) reported moderate to severe depression intensity levels while 91 participants (43.8%) reported moderate to severe anxiety intensity levels. The degree of dependence on nicotine was negatively related to the intensity of anxiety and depression experienced by coronary patients. Additionally, the degree of nicotine dependence, anxiety and depression was associated with various sociodemographic and clinical factors such as educational level, social support, and information on their condition and treatment.

Conclusion: Overall, the findings of this study point to an inverse relationship of nicotine dependence, depression and anxiety. However, this paradoxical association could be a product of shared risk factors or confounding. Nonetheless, the development of individualized educational and supportive interventions to quit smoking in coronary patients should primarily focus on the assessment of depression and stress.

Keywords: Anxiety; Depression; Nicotine Dependence; coronary heart disease.
