    Abstract:
    INTRODUCTION: Cardiac rupture (CR), involving left ventricular free wall, interventricular septum or papillary muscles, accounts for 15% of all deaths in the acute phase of myocardial infarction (MI). After cardiac arrhythmias and cardiogenic shock, CR is the third most common cause of death in acute MI. In spite of progress in the treatment of MI, mortality due to CR did not change in recent years.Aim. To assess the incidence, clinical course and outcome in patients with acute MI complicated by CR who were treated in our centre. METHODS: The study group consisted of 697 consecutive patients who were hospitalised due to acute MI with ST segment elevation (STEMI). The in-hospital and three-month follow-up data were analysed in 27 (3.9%) patients who developed CR. In 20 patients CR occurred in the left ventricular free wall, in 5 interventricular septum, in one both of these structures, and in one papillary muscle. The diagnosis of CR was based on clinical presentation and echocardiography. RESULTS: The overall mortality in 697 patients with STEMI was 10.5%. Mortality rate in patients with CR was 55.6% (15 patients) which accounted for 20.5% of all deaths. Nine patients with CR underwent cardiac surgery whereas 18 were treated conservatively. Two (22.2%) patients from the former group and 13 (72.2%) patients from the latter group died. CONCLUSIONS: 1. Mortality due to CR was increased in patients who were treated conservatively, who received thrombolysis and those who were females. 2. Rapid and accurate diagnosis, proper correction of hemodynamical disturbances and timely introduction of cardiac surgery improve prognosis in patients with CR complicating STEMI.
