There has been mounting evidence suggesting that psychosocial factors, including anger proneness, depression and social isolation, are risk factors for coronary heart disease (CHD). 1,2 Studies have shown a positive relationship between anger proneness and CHD risk factors. The Atherosclerosis Risk in Communities (ARIC) Study found that anger proneness was an independent risk factor for CHD among normotensive, middle-aged men and women. 3 A meta-analysis reviewing several major epidemiological studies concluded that depression is an independent risk factor in the development of CHD in initially healthy people, with an overall relative risk of 1.64. 4 Other studies have also shown that depression increases short and long term mortality risk in patients with known CHD. 5,6 Lack of social support also portends a poor prognosis in patients after myocardial infarction (MI). 7,8 For example, among MI survivors, those with low to moderate levels of perceived social support had a 1-year post-CHD mortality rate about twofold higher than those with high levels of social support. 9 Furthermore, there is an interaction between depression and social support in relation to MI survival. 9 Although epidemiologic evidence is indicative, the results of psychosocial interventions after MI have
