Anxiety and depression are common in people with coronary heart disease, predicting worse outcomes. In the general population depression and anxiety increase the risk of developing coronary heart disease. By using the baseline data from the 45 and Up Study, this project will examine the relationship between a history of anxiety and/or depression and the onset of coronary heart disease. It will also compare psychological distress following a cardiac event between those with and without a history of either anxiety or depression.
