The spectrum of death after myocardial infarction: a necropsy study.

Author information

Department of Cardiology, University of Limburg Academic Hospital.


To determine the relative frequency of the causes of death in the acute (less than 24 hours), early (24 hours to 3 weeks), and chronic (greater than 3 weeks) phases of myocardial infarction, data from all autopsies performed at a university hospital during a 56-month period were reviewed. Autopsies were performed in 56% of in-hospital deaths and 27% of patients dead on arrival in the emergency room (out-of-hospital deaths). In 271 cases of suspected cardiac death, a myocardial infarction of any age was identified. Death had occurred in the acute phase of a first infarction in 19 patients and was most frequently due to pump failure (37%) followed by cardiac rupture (26%) and arrhythmias (21%). Death had occurred 24 hours to 3 weeks after a first infarction in 80 patients and was most frequently due to pump failure (44%), rupture (27%), and arrhythmias (16%). Recurrent acute infarction was found in 32% of patients whose deaths were due to arrhythmias or pump failure and in 19% of those whose deaths were due to rupture. Death had occurred greater than 3 weeks after a first infarction in 172 patients. In 132 (77%) of these patients death was due to a complication of a new acute or recent infarction. Myocardial rupture was a less frequent cause of death in patients with recurrent infarction (8%) than in those dying in the acute or early phase after their first infarction (27%, p = 0.0009). A primary arrhythmia in the absence of recurrent infarction or ischemia accounted for only 14% of out-of-hospital deaths late after an infarction.(ABSTRACT TRUNCATED AT 250 WORDS).
