title: [Effect of periodicity of many days on the outcome of myocardial infarct in males].
abstract: The existence of an endogenic biological rhythm of 42-day duration, determining both the moment of development and the outcome of myocardial infarction, is shown. Mortality was highest among persons who had acquired the disease in the first and fourth weeks of this period. This may also testify to the existence of a 21-day cycle of periodicity which has an effect on the outcome of the disease.
