title: Trends in the incidence of the free wall cardiac rupture in acute myocardial infarction. observational study: experience of a single center.
abstract: OBJECTIVE
  Free wall cardiac rupture (CR) is one of the most common cause of in-hospital death in acute myocardial infarction (AMI). The early diagnosis of CR and selection of the patients predisposed to CR become an important clinical tool.
  
  
  OBJECTIVE
  assessing the occurrence of CR in patients with AMI, to determine the factors which could help to identify the patients threatened with CR.
  
  
  METHODS
  2320 consecutive patients with AMI. CR was proved by autopsy or by echocardiography performed during cardio-pulmonary resuscitation (CPR).
  
  
  RESULTS
  In-hospital mortality was 11% (254 patients). 50 patients (2%) died from CR. CR was the cause of 20% of total in-hospital death. Patients with CR were older than survivors (72 vs 60 years, p<0.0001). Women prevailed in CR group: (62% in CR group vs 27% in the survivors, p<0.01). 29% of patients were treated with thrombolytics (Th+). Out of 58 patients from Th (+) group who died, 17 (29.31%) died because of CR. CR occurred in 33 (16.8%) patients out of 196 died in Th (-) group. In the logistic regression analysis only age and sex remained as predictors of CR. 16 patients died from CR during first 24 h from admission (ECR). In 34 patients CR occurred >24 h (LCR). In ECR group were no prevalence of women, while in LCR women constituted 68%. In ECR group all but one patient had no previous history of MI (p=0.06). Frequency of thrombolythic therapy was equal.
  
  
  CONCLUSIONS
  Advanced age patients, particularly women with first AMI are at risk of CR. Decision of thrombolytic treatment in this group of patients must be very cautious.
