title: [Prognosis after late versus early nonfatal myocardial infarction].
abstract: Many recent studies have identified nonfatal recurrent myocardial infarction (RNMI) as the most significant predictor for later outcome. Almost all of these studies have been based on the studies of RNMI in the first year after the index infarction. The prognosis after late RNMI has not been studied properly. In 3,867 nonselected patients below 76 years of age with an acute myocardial infarction we studied the prognosis after a first RNMI depending on the year of its occurrence after the index infarction. Mortality was estimated by the method of Kaplan-Meier and the differences were evaluated by means of the Tarone-Ware test. Four hundred and ninety-three (13.6%) patients had a first RNMI in the first, 151 (5.4%) in the second, 105 (4.2%) in the third, and 71 (3.8%) in the fourth year after the index infarction (group 1-4). One-year mortality rate after RNMI was 23.7% in the first group, 24.1% in the second, 17.5% in the third, and 22.8 in the fourth group. When all the groups were compared with each other no significant difference was found between the mortality rates (p = 0.12) or Standardised Mortality Rates. We concluded that late and early RNMIs have almost the same grave prognosis.
