Abstract

In 19 patients wiht myocardial infarction during 7 weeks after the onset of the infarction the serum activities of the leucine aminopeptidase (LAP) and of the alanine aminopeptidase (AAP) were determined. Here an increase of the LAP-values with a maximum in the 1st week was found. Apparantly a hypoxic lesion of the hepatocytes is to be regarded as cause for this. In patients with shock symptomatology as well as with heart decompensation the AAP-activities were on the average higher than in the cases with myocardial infarction without these alterations during the whole period of observation. In all myocardial infarctions the AAP-zymograms showed an additional anodic AAP-fraction as it was observed in previous investigations in cholestasis.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiogenic Shock

Cardiogenic shock is a devastating consequence of acute myocardial infarction and is associated with an extremely high mortality. Here is the latest research.
