AbstractDepression has been associated with adverse outcomes in patients with cardiac disease. Data on its prevalence and the factors influencing it are limited in the cardiac rehabilitation program (CRP) setting. To elucidate the prevalence of and the factors that influence depression in patients attending CRP. Patients attending the CRP from 2003 to 2016 were included in the study. All patients had a Beck Depression Inventory-II (BDI-II) performed prior to commencement in CRP and were followed longitudinally. The BDI-II for the 4989 patients were as follows: 0 to 13 (normal) = 3623 (72%); 14 to 19 (mild depression) = 982 (20%); 20 to 28 (moderate depression) = 299 (6%); 29 to 63 (severe depression) = 85 (2%). The BDI-II (mean ± SEM) for males (mean age: 60.8 ± 0.1 years) and females (mean age: 63.4 ± 0.3 years, P < .001) were 7.0 ± 0.1 and 8.5 ± 0.2 (P < .001), respectively. Elevated BDI-II scores (14-63) were more common in type 1 (41.1%) and type 2 (30.5%) diabetics than nondiabetics (25.7%). Similarly, elevated scores were more common in smokers (36.1%) than never-smokers (24.7%). The BDI-II scores for Caucasians, South Asians, and East Asians were 7.3 ± 0.1, 8.0 ± 0.3, and 7.0 ± 0.3 respectively (P = .01 for CA vs SA by 1-way ANOVA and least significant difference test). The prevalence of depression is high in patients attending CRP affecting 28% of the population. BDI-II is a simple validated screening tool that can be applied to patients attending CRP. Diabetics, current smokers, and South Asians all had a higher prevalence of depression.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
