Comparison of psychological risk factors among patients with and without myocardial infraction relapses

This research has been established with the aim of the comparison of psychological risk factors such az depression، anxiety، psychosocial stress، type D personality، mindfulness among patients with and without myocardial infarction relapse. In this quasi-experimental study، 60 heart patients were selected amoung the patients admitted to the H. Zahra hospital in Sari city (Iran). The patient divided into two groups: 30 patients with one myocardial infarction and 30 patients with two or more myocardial infraction. Psychological risk factors such as type D personality، depression، anxiety، psycho-social stress، mindfulness were evaluated by the questionnaires including Denollet type D personality، anxiety، depression and stress Lovibond & Lovibond and Brawn & Ryan’s mindfulness scales. No significant differences were found between two groups regarding to blood pressure، heredical problem، diet، kidney stone، cholesterol (LDL)، smoking، and diabetes (P> 0. 05). Anxiety with a direct effect (P=0. 017) and type D personality with an indirect effect (P = 0. 011) could predict relapse of myocardial infraction (p<0. 05)، but depression and psychosocial stress and mindfulness could not have any effect on the prediction of myocardial infraction relapse (P> 0. 05). Given the role of anxiety and type D personality in myocardial infraction، it is suggested for the sufficient training to reduce anxiety and inhibition of expression of negative excitement and social dissuasion to prevention of relapse myocardial infraction
