title: [Myocardial infarction and late pericarditis].
abstract: The post-infarction syndrome was observed in 8 out of 138 consecutive patients with acute myocardial infarction; 24 other cases of the post-infarction syndrome diagnosed over the preceeding 3 years were also reviewed. In order to determine the clinical significance and the prognosis, this group of 32 was compared to another of 105 patients with myocardial infarction without pericarditis, with respect to age, sex, medical history and characteristics of the underlying necrosis (location and size). Several clinical signs are discussed. This study showed the post-infarction syndrome was associated with large infarcts, the course of which was marked by arrhythmias, conduction defects and haemodynamic problems. A considerable inflammatory syndrome was often observed. The relation between the post-infarction syndrome and early pericarditis is not proved; on the other hand, a close correlation between late pericarditis, atrial fibrillation and left pleural effusion was demonstrated. The long term prognosis of infarcts complicated by the post-infarction syndrome is without doubt determined by the size of the necrosis and by the presence of ventricular aneurysms which are frequently associated.
