Abstract
Aim: This study identified the factors associated with
depression in patients diagnosed with myocardial
infarction (MI) who underwent percutaneous coronary
intervention (PCI).
Methods: We searched the literature using PubMed
and CINAHL from their inception in 1946 to
December 2014. The search terms were “myocardial
infarction,” “depression,” and “percutaneous coronary
intervention.” Studies which investigated
factors associated with depression in patients
diagnosed with MI who underwent typical medical
procedures were searched.
Results: Eleven studies met our inclusion criteria.
None of these limited their samples to patients with
MI who underwent PCI. Twenty-one factors were
identified as possible risk factors for depression in
patients who were diagnosed with MI and underwent
PCI: gender; negative illness beliefs; neuroticism;
autonomy; baseline depression scores; previous
diagnosis of depression, anxiety, or stress; smoking;
marital status; Type D personality; procedure; length
of hospital stay; fat intake; functional disability;
time engaged in physical activity; social support;
and a history of angina, MI, coronary artery bypass
graft surgery, PCI, diabetes mellitus, and stroke.
Conclusions: This review suggests that these 21
factors should be considered in future studies as
possible independent variables or covariates of
depression among MI patients who have undergone
PCI.
