[Quality assurance in acute myocardial infarct]

The Ludwigshafen myocardial infarction project has demonstrated, that an intense public media campaign can reduce prehospital delays in acute myocardial infarction. With an additional intrahospital improvement, this can lead to a better and more frequent use of recanalization (thrombolysis or percutaneous transluminal coronary angioplasty [PTCA]). Several large multicentric registries (60 minutes myocardial infarction project, MIR, MITRA) with a total of about 40,000 patients at over 300 hospitals in Germany showed, that intrahospital improvement of infarction therapy can also be achieved in other hospitals. Voluntary participation in an infarction registry leads to quality control and improvement. Two factors are especially important: (1) documentation of every infarction patient, and (2) documentation of the reasons why therapy was given or withheld in every single patient. The improvement in early therapy is associated with a 20% reduction of hospital mortality (MITRA-1). The media campaign in Ludwigshafen to reduce pre-hospital patient delay, however, could not yet be carried out in other areas effectively and intensely enough.
