Abstract :
Background: Conducted researches show that psychological factors may have a very important role in the etiology, continuity
and consequences of coronary heart diseases. Th is study has drawn the psychological risk and protective factors and their eff ects
in patients with coronary heart diseases (CHD) in a structural model. It aims to determine the structural relations between
psychological risk and protective factors with quality of life in patients with coronary heart disease. Materials and Methods: Th e
present cross-sectional and correlational studies were conducted using structural equation modeling. Th e study sample included
398 patients of coronary heart disease in the university referral Hospital, as well as other city health care centers in Isfahan city.
Th ey were selected based on random sampling method. Th en, in case, they were executed the following questionnaires: Coping
with stressful situations (CISS- 21), life orientation (LOT-10), general self-effi cacy (GSE-10), depression, anxiety and stress
(DASS-21), perceived stress (PSS-14), multidimensional social support (MSPSS-12), alexithymia (TAS-20), spiritual intelligence
(SQ-23) and quality of life (WHOQOL-26). Results: Th e results showed that protective and risk factors could aff ect the quality
of life in patients with CHD with factor loadings of 0.35 and −0.60, respectively. Moreover, based on the values of the framework
of the model such as relative chi-square (CMIN/DF = 3.25), the Comparative Fit Index (CFI = 0.93), the Parsimony Comparative
Fit Index (PCFI = 0.68), the Root Mean Square Error of Approximation (RMSEA = 0.07) and details of the model (signifi cance
of the relationships) it has been confi rmed that the psychocardiological structural model of the study is the good fi tting model.
C onclusion: Th is study was among the fi rst to research the diff erent psychological risk and protective factors of coronary heart
diseases in the form of a structural model. Th e results of this study have emphasized the necessity of noticing the psychological
factors in primary prevention by preventive programs and in secondary prevention by rehabilitation centers to improve the quality
of life of the people with heart diseases.
