[The characteristics of those who have died with primary or recurrent myocardial infarct].

Le résumé fourni par la source

In 93 decreased patients, 31 with first myocardial infarction and 62 with repeated myocardial infarction, the following indices were studied: risk factors, previous history, clinical onset, complications, ECG localization, time and cause of death, pathologicoanatomical changes. There was a tendency toward a greater frequency of cardiogenic shock in the patients who died during their first infarction. In the patients who died during a repeated infarction the following events were significantly more frequent: pulmonary thromboembolism (9.6%), dilatation (8.1%), recurrence (8.1%) (p less than 0.01); chronic cardiac failure (25.8%), episodes of clinical death (25.8%) (p less than 0.001); conduction-rhythm disturbances (75.8%) (p less than 0.05). Transmural infarction was found in 96.7% of the patients of the first infarction group vs 82.2% of the patients of the repeated infarction group (p less than 0.05). A statistically significant difference for the time of death was found only for the group patients who died after the 7th day of the infarction--0% for the first infarction group and 25.8% for the repeated infarction group (p less than 0.001). Cardiogenic shock was a significantly more frequent cause of death for the patients of the first infarction group (87.1%) than for the patients of the repeated infarction group.
