title: [Cardiac rupture: a not infrequent complication of acute myocardial infarction. Report of five cases (author's transl)].
abstract: Five cases of cardiac rupture (CR) in acute myocardial infarction (AMI) (four men and one woman aged between 49 and 86 years, mean 64) are described. The incidence of CR was 4,7% of 106 cases of AMI and 20,8% of causes of death. In all cases, pathologic observations well agreed with electrocardiographic site of infarction. All patients had ECG pattern of transmural AMI: postero-inferior (2 cases), anterior (1 case); none of them had myocardial infarction in the past. Two patients had systolic hypertension on admission, during and immediately before death, and 3 patients were normotensive during the whole course of illness. All patients had severe, prolonged and resistant to opiate therapy chest pain, which reexacerbated immediately before death in two cases. 4 patients died within 24 hours after the onset of symptoms. Terminal ECG pattern was similar in these four cases: sudden sinus bradycardia and/or idio-ventricular rhythm, with a progressive slowing of heart rate and changes of QRS patterns of "agonic" type, preceded electrical activity cessation. In one patient, who died at the seventh day of illness, ventricular fibrillation was observed. The AA. stress the importance of the early recognition of clinical findings suggesting an impeding CR in order to relieve cardiac tamponade with pericardiocentesis and to perform, as soon as possible, surgical treatment.
