The impact of angina and cardiac history on health-related quality of life and depression in coronary heart disease patients.

Objective: To prospectively examine the contribution of angina and cardiac history to health-related quality of life (HRQoL) and depression in cardiac patients, over 6 months post-hospitalization.
Methods: Participants were myocardial infarction (MI), percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) outpatients under the age of 70 years. One hundred and seventy-one patients consented to participate, with 121 patients being retained 6 months later (71% response rate). The impact of the patient's cardiac history and the presence of angina on physical, social and emotional HRQoL and depression was examined.
Results: At baseline, cardiac history was not significantly related to any of the dimensions of HRQoL or depression. At 6-month follow-up, cardiac history significantly predicted a higher level of depression, and angina was predictive of a significantly worse emotional, physical and social HRQoL and a higher level of depression.
Discussion: The presence of a cardiac history is associated with depression 6 months post-cardiac event, and angina is associated with both an adverse HRQoL and higher levels of depression. As past research has demonstrated that depression is a risk factor for mortality in patients with established heart disease, it is important from both a clinical and a research perspective to address these issues.
