Randomly selected males who suffered from myocardial infarction (MI) were examined. The investigated group was subdivided into two: the patients with no ischemic heart disease (IHD) preceding MI and patients with IHD symptoms occurring prior to MI. The compared groups differed significantly in some psychological parameters and clinical features of MI.
