Frailty is prevalent among patients with advanced symptomatic heart failure referred for heart transplantation and is associated with increased mortality.
This study evaluated associations between chronic breathlessness and: anxiety; depression; functional status in the general population.
MethodsThis cross sectional cohort of consenting adults (≥18 years) used an online survey. Quota sampling (n=3,000) was employed reflecting the 2016 national census for sex, age and place of residence. Other data included: Patient Health Questionnaire for Depression and Anxiety (PHQ-4); the modified Medical Research Council (mMRC) breathlessness scale and the Australia-modified Karnofsky Performance Scale (AKPS). Multinomial logistic regression assessed predictors.
Results2977 respondents had all relevant scores; female-51.2%; median age 45.0 (range 18-92). Prevalence of breathlessness (mMRC ≥ 2) was 2.4%; anxiety 6.0%; depression 2.7%; coexisting anxiety/depression 6.1% and poorer functional status (AKPS ≤60) 1.6%.Poorest function was in the co-existing anxiety/depression group with 11.6%. The highest proportions of people with breathlessness were found in the co-existing anxiety/depression group (10.6%) and depression only (8.8%).In multinomial regression, depression only and co-existing anxiety/depression were predicted by older age, longer duration of breathlessness, and poorer functional status (AKPS ≤60). The relationship between poorer functional status and co-existing anxiety/depression was striking (OR 16.1; 95% 8.3, 31.4).Adjusted odds ratios for breathlessness and: depression only was 5.5 (95% CI 2.3,12.9); and 5.1 for co-existing anxiety/depression group (95% CI 2.7,9.7).
ConclusionClinically important breathlessness (mMRC ≥2) was associated with depression only and coexisting anxiety/depression. Poorer function associated with psychological morbidity in the general population requires further research.
