Data were gathered using Short-form heath survey 36 items (SF36) and Type-D Personality Inventory, and were analyzed via analytic tests in SPSS v.20.
Results: Finding showed that CHD patients (Men: 107/73± 21/58, Women: 95/96± 13/049) had lower quality of life in comparison with controls (Men: 14/96± 4/46, Women: 103/82±13/06) and had higher Negative affect (Men:�14/96±4/46,�Women:�16/62±3/64) in comparison with controls (Men:�12/50±2/41,�Women:�12/92±4/46). 26 percent of the variance related to the development of CHD was due to happinen, negative affect, physical pain and physical limitations.
