[Determination of serum haptoglobin concentration in the acute phase of myocardial infarct by means of Mancini's simple radial immunodiffusion test].

In 14 patients with an according to the WHO-criteria definitive myocardial infarction quantitative serum haptoglobin course controls were performed in the first week after the pain event. The haptoglobin estimations were performed by means of simple radial immunodiffusion after Mancini on M-partigen plates. Up to the fifth day after the pain event an increase of the haptoglobin concentration could be established. On the two following days a decreasing tendency could be observed. In a comparative group of five with chronic ischaemic heart diseases and angina pectoris syndrome under the same conditions of examination no increase of haptoglobin could be observed during the first five days after the pain event. These examination results correspond with the literary data, that in disease with tissue destruction increases of haptoglobin are to be observed.
