Abstract
Background: Studies suggested that there is an association between depression and CHD. Some studies indicated that diagnosis and treatment of depression in patients with CHD would result in a better diagnosis. Purpose: The main purpose of this review is to answer this question: does diagnosis and treatment of depression result in better health outcomes in Coronary Heart Disease’ (CHD) patients? Design: The design of this review was based on the relationship between depression as an independent variable, and CHD as a dependent variable. Plus, the link between them was discussed in details suggesting that there is a strong evidence for association between depression and CHD. Diagnosis and Treatment Methods: Different studies have used a variety of measures to diagnose depression, such as DSM-IV, PHQ-2, and PHQ-9. In addition, they have also treated depressive symptoms by using several methods, including invasive and non-invasive procedures.
