title: [Complications of myocardial infarction between the 2d and 4th week].
abstract: The complications of myocardial infarction after transfer from the Coronary Care Unit on the 6th day were analysed bu a retrospective study of 3,460 computerised case reports (1973-1980). The mortality rate was 6% (1/3 of hospital deaths) in the period from the 7th day to discharge from hospital (14th to 30th day). Cardiac arrest as not uncommon (20% of all cardiac arrests) but the prognosis was better thn during the initial phase (p less than 0.05) as the mechanism was more commonly ventricular fibrillation or tachycardia (p less than 0.05). This series was compared with a similar population from 1970-1973; an improvement was observed in global hospital mortality (27% previously compared to 17%, in the study series, p less than 0.001). As the population were comparable, this phenomenon seems to be related to better treatment of shock and cardiac failure and the advances in cardiac surgery during the initial phase of infarction. Thd commonest mechanical complication was ventricular aneurysm; its occurrence does not influence the vital prognosis during this period. The incidence of cardiac arrest and death due to cardiac failure is not negligible after the first week of myocardial infarction. Therefore, we do not believe that the hospital period should be reduced after myocardial infarction. Special training of the nursing staff is essential for the successful treatment of these complications. The global prognosis could be improved by the rehabilitation of digitalis therapy and the introduction of new sympathomimetic amines in the acute phase of myocardial infarction.
