Depression is commonly present among HF patients and is associated with adverse clinical outcomes. However, research regarding its association with New York Heart Association (NYHA) class is still scarce.

To evaluate the presence of depression symptoms in HF outpatients and analyze its association with NYHA class.

This study is part of a larger research project (Deus Ex-Machina/NORTE-01-0145-FEDER-00026). HF patients were recruited from an outpatient clinic at a University Hospital. Exclusion criteria were: unable to communicate, severe visual acuity deficit or NYHA class IV. Sociodemographic data and NYHA class were registered. The Patient Health Questionnaire-9 (PHQ-9) was used to assess depression, with a score ≥10 indicating clinically relevant depression.

A sample of 136 HF patients was included, with a median age of 59 (range: 24-81) years old, where 66% were men. Almost half of the patients (49%) were in NYHA class II, followed by class I (36%) and class III (15%). The median score of PHQ-9 was 4(range:0-18), with 26% showing clinically relevant depression. PHQ-9 total score was associated with NYHA class (p=0.001), with higher median scores in worse NYHA classes [class I: 3 (IQR: 5.5), class II: 4 (IQR: 8) and class III: 8.5 (IQR:9.3)].

In this study, depression was present in 26% of HF outpatients and was associated with more severe HF symptoms. Consequently, preventing, monitoring, and treating depression in the management of these patients is recommended. Further research is needed for a deeper analysis of this association.

Heart failure (HF) is a worldwide public health problem and the main cause of morbidity and mortality in older people. Previous studies have demonstrated that psychological symptoms are associated with worse cardiovascular outcomes. Nevertheless, the research regarding the association between anxiety and HF is still scarce.

To analyse the levels of anxiety in HF patients and its association with New York Heart Association (NYHA) class in HF patients.

This study takes part of a wider project named Deus Ex-Machina project (NORTE-01-0145-FEDER-00026). HF patients were recruited from an outpatient clinic at a University Hospital. Patient with inability to communicate, with severe visual impairment or with NYHA class IV were excluded. Sociodemographic data and NYHA class were recorded. Anxiety was assessed using the Generalized Anxiety Disorder-7 (GAD-7).

Overall, 136 patients were included, with a mean age of 57(±13) years old. Most of them were men (66%) and married (76%), with mean education of 8 years (±4). Regarding NYHA class, 36%, 49% and 15% were at class I, II and III, respectively. The mean GAD-7 total score was 6.4 (±5.2) and 32% of patients showed moderate to severe anxiety symptoms. No association between the NYHA functional class and anxiety was found (p=0.106).

The results reveal that anxiety is frequent among HF patients. However, as found in previous studies, it was not associated with more severe HF symptoms. The coexistence of HF and anxiety deserves further studies, in order to build a better understanding of this association.
