[The unrecognized myocardial infarction]. / Der nicht erkannte Myokardinfarkt.

BACKGROUND AND OBJECTIVES: despite the improved quality of diagnostic technology, myocardial infarction still belongs to the diseases that are most frequently overlooked. Especially asymptomatic patients or patients with atypical symptoms are more common to be misdiagnosed. Failure to correctly diagnose is the leading cause of malpractice claims. It was the aim of this study to evaluate the records of patients who died from myocardial infarction and to analyse whether medical malpractice had occured in those who had undergone a medical examination shortly before their death. METHODS: in the years 2008 and 2009 myocardial infarction had been diagnosed in 109 auotopsies performed at the Institute of Legal Medicine of the Hanover Medical School. The records of these patients who had died from myocardial infarction were retrospectively analysed with particular emphasis on an antemortem medical consultation, reported symptoms and diagnostic measures. RESULTS: in 38 persons (34.9 %) an antemortem medical consultation or hospitalisation has taken place, whereby in five persons the diagnosis of myocardial infarction was suspected. In 33 persons, a myocardial infarction could not be diagnosed antemortem. In two cases an additionally cardiologic assessment was recommended to estimate if medical malpractice was present and in another two cases with insufficient diagnostic measures medical malpractice was reproached from forensic pathologists. CONCLUSION: autopsy give the most accurate diagnostic information. On the other hand, it may provide an effective defence against medical malpractice litigation.
