About ruptures of the heart muscle in myocardial infarction

The medical histories of those who died from heart rupture (PC) were analyzed. Of the 1499 patients with myocardial infarction (MI) who were admitted to the specialized department for patients with myocardial infarction from 1972 to 1978, 221 died; PC was the direct cause of death in 56 of them (25.3%). MS was mainly observed in the elderly, more often in women than in men. In the 51-60 age group, PC occurred in 5 out of 284 men (1.8%) and in 3 out of 70 women (4.3%), in the 61-70 age group - in 8 out of 270, respectively (2.9 %) and 18 out of 191 (9.4%); in the group of MI patients over 70 years old - in 5 out of 107 (4.7%) and in 17 out of 155 (10.9%). In all patients, MS occurred against the background of transmural MI in the anterior wall region. More often MS was observed in primary MI (76.7%), in 2 cases with repeated MI (3.3%), in 12 with recurrent MI (20.0%). On the first day of myocardial infarction, cardiac rupture occurred in 30 patients, on days 2-3 - in 10, on 4-7 - in 2, on 19-23 - in 8. All cases of late ruptures (after 7 day) were associated with recurrent myocardial infarction.
