Change over time in posttraumatic stress caused by myocardial infarction and predicting variables

The traumatic experience of a heart attack may evolve into symptoms of posttraumatic stress disorder, which can be diagnosed at the earliest 1 month after myocardial infarction (MI). While several predictors of posttraumatic stress in the first year after MI have been described, we particularly sought to identify longer-term predictors and predictors of change in posttraumatic stress over time.
