Key result
Sleep disturbance affects ~69% of post-cardiac patients and is linked to worse adherence and depression.
Why the study?
The prevalence of sleep disturbance and its relationship with treatment adherence, self-efficacy, anxiety, and depression in cardiac patients over 12 months was unclear.
Population

Comparison
Sleep disturbance presence vs absence
Design
Prospective cohort study with repeated interviews
Follow-up

May support screening for persistent sleep disturbance post-cardiac event; leaves open whether intervention improves adherence and mood.
Cohort (n=134)
Yes
Sleep disturbance is highly prevalent following a cardiac event, and its persistence at 4 months is associated with worse psychological outcomes and reduced treatment adherence at 12 months.
Grande et al. (2015) conducted a cohort in Cardiac event (acute myocardial infarction, bypass surgery, or percutaneous coronary intervention) (n=134). Sleep disturbance was evaluated on Prevalence of sleep disturbance and its relationship with treatment adherence, self-efficacy, anxiety and depression. Sleep disturbance was highly prevalent (69%) at 6 weeks post-cardiac event, and its presence at 4 months was associated with reduced treatment adherence and higher anxiety and depression at 12 months.
