High incidence of anxiety and depression in patients with coronary artery disease can be associated with serious complications consisting increasing mortality and morbidity and adverse cardiac events. Therefore، this study was conducted to evaluate the incidence of anxiety and depression in patients with coronary artery disease.

This cross-sectional study was conducted in Jamaran heart hospitals; Tehran in 2010 and a total sample size of 300 patients with coronary heart disease were investigated. Convenience sampling method was used to select patients. Hospital Anxiety and Depression scale (HADS) was used for assessment of anxiety and depression. The data were analyzed by SPSS software، version 17، and descriptive and inferential statistic tests were used.

The mean and standard deviation scores for anxiety and depression subscales were، (2. 6) 7. 23، and (2. 6) 6. 74، respectively. Of the patients، 45. 7% had depression and 38% had anxiety. There was statistically significant relationship between age and depression، also anxiety and depression levels (r=0. 67). Patients with a history of hypertension had more anxiety and depression levels (P<0. 05).

Results of this study showed a high incidence of anxiety and depression in patients with coronary artery disease، respectively. Therefore، recommendations for further assessment of the mental status of the patients at admission and planning appropriate interventions according to screening outcomes is recommended.

Anxiety and depression have a high prevalence rate in patients with coronary artery disease, leading to reduced treatment outcome in these patients. Therefore, the present study has been conduced to compare anxiety and depression among patients with coronary artery disease based on proposed treatment. Anxiety and depression were compared through a standardized hospital anxiety and depression questionnaire (HADS) in 300 patients, in need of drug therapy, percutaneous coronary angioplasty (PCI), or coronary artery bypass graft (CABG), admitted to male cardiac unit of internal medicine department of Jamaran hospital, Tehran, in 2010, for coronary angiography. Data were analyzed by SPSS17 statistical software using ANOVA, Kruskal-Wallis, and chi-square. Incidence of depression was higher in patients candidate for CABG than the other two groups; likewise, level of anxiety was more in those with PCI as well as CABG compare to drug treatment group (p<0.05). In total, 38 and 45.7 percent of patients underwent some degrees of depression and anxiety respectively. Regarding high prevalence of anxiety and depression among patients with coronary heart disease and its negative impact on treatment outcome, appropriate screening and therapeutic approaches have to be applied for this group of patients.
