Causal Attributions and Perceived Severity as Predictors of Posttraumatic Stress Symptoms after a First Myocardial Infarction

Author
Abstract
Recent meta-analyses have shown a significant link between symptoms of anxiety and depression, and cardiovascular diseases (CVDs). The presence of these symptoms has a direct impact on the course and the recovery from the CVDs. A less analyzed aspect is the role played by the stress induced by the onset of CVDs conditions and, especially, by acute myocardial infarction (AMI). In this study, we assessed posttraumatic stress symptoms (PTSS), emotional state, health habits, and subjective perception of the event and causal attributions regarding the infarct, in a sample of 76 patients who had suffered an AMI in the previous 48-72 hours. Structural equation analyses and path analyses showed that the severity of PTSS was predicted by the perceived severity of the AMI and by two specific beliefs (i.e., considering that the AMI is a hereditary condition and that the help of others will not be beneficial). The results suggest the possibility of early identification of patients with a higher risk of suffering a high level of stress derived from the AMI. Based on this evidence, we discuss the possibilities of making effective interventions to reduce these symptoms, often ignored in clinical practice, and improve the medical and psychological prognosis of people with AMI.
