Comparison of the hospital anxiety and depression among patients with coronary artery disease based on proposed treatment

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.
