Many psychological factors influence the onset and prognosis of heart disease, among the most studied, there are personality traits, depressive and anxious experiences. Type D personality, characterized by high levels of social inhibition and negative affectivity, is associated with unfavourable prognosis for cardiac patients. Depressive and anxious symptoms influence the onset of cardiac disorders, the management of the disease and their impact on quality of life. Aim of this study is to evaluate the impact of cardiac rehabilitation on social inhibition, negative affectivity, anxious and depressive symptoms in cardiac patients. Patients were recruited at the Rehabilitation Cardiology Unit of Cittadella Hospital, after an acute cardiac event, they were enrolled to attend a cardiac rehabilitation program.
