The aim of this study is to evaluate the frequency and prognostic significance of ventricular arrhythmias (VA) and of ST‐T changes found during 24‐h ECG recording in patients who survived an acute myocardial infarction. Eighty‐nine patients (2 females and 87 males) discharged from hospital after acute myocardial infarction were studied. Mean age was 52.2 years (SD±10) with a range of 26–68. Serial observations were carried out at 1, 2, 3, 6, and 12 months after the acute event. Eight patients died during the first two years of follow‐up, of these, 2 deaths were of noncardiac origin: one was due to gastric carcinoma and the other to pulmonary neoplasm. Of the 6 cardiac deaths, 4 were sudden and unexpected and 2 were due to reinfarction. Statistical analysis of the results obtained in the first three months of follow‐up has not shown any significant correlation between pathologic patterns and cardiac death. In the second period we found a statistically significant relationship between cardiac death and multiform VPBs (p<0.05), CVA (p<0.05), and ST‐T changes (p<0.05). More significant was the correlation between cardiac death and the presence at the same time of ST‐T changes and multiform VPBs (p<0.01).
