Association between heart-focused anxiety, depressive symptoms, health behaviors and healthcare utilization in patients with coronary heart disease

OBJECTIVE: To analyze the association between heart-focused anxiety, depressive symptoms, health behaviors and healthcare utilization in patients with coronary heart disease (CHD).

METHODS: N = 1007 patients with CHD were recruited in hospital and followed for one year in a two-site cohort study. Heart focused anxiety (Cardiac Anxiety Questionnaire [CAQ] with the three subscales fear, attention, and avoidance), depressive symptoms (depression module from the Patient Health Questionnaire [PHQ-9]), health behaviors and healthcare utilization (smoking status, alcohol consumption, physical activity, outpatient physician/psychotherapist visits) were assessed six months after the initial hospitalization. Multiple regression models were used for statistical analysis.

RESULTS: About one third of the sample exhibited clinically significant CAQ scores. Higher CAQ-avoidance scores were associated with current smoking (OR = 1.62; 95%CI: 1.33-1.98), reduced alcohol intake (OR = 0.83; 95%CI: 0.71-0.98), non-participation in a coronary exercise group (OR = 1.76; 95%CI: 1.42-2.17), less regular physical activity (OR = 2.69; 95%CI: 2.32-3.12), and more frequent contact to general practitioners (GPs; b = 0.07, SE: 0.03). CAQ-attention was associated with non-smoking (OR = 0.51; 95%CI: 0.37-0.70), exercise group participation (OR = 0.69; 95%CI: 0.51-0.94), more frequent regular physical activity (OR = 0.55; 95%CI: 0.44-0.68), and more frequent contact to specialists for internal medicine (b = 0.09, SE: 0.04). CAQ-fear was not associated with any of the health behavior or healthcare use measures. Depressive symptoms were associated with reduced regular physical activity (OR = 1.05; 95%CI: 1.02-1.08) and increased contact to mental care specialists (b = 0.03, SE: 0.01) and GPs (b = 0.02, SE: 0.01).

CONCLUSIONS: Heart-focused anxiety and depressive symptoms may impede secondary prevention in patients with CHD and increase outpatient healthcare utilization.
