BACKGROUND: Early reperfusion by direct percutaneous coronary intervention (PCI) in patients with ST segment elevation acute myocardial infarctions (STEMI) with an out-of-hospital cardiac arrest (OHCA) reduces hospital and longterm mortality. AIMS: Evaluating the significance of direct PCI for the short-term (discharge from acute hospitalization) and 1-year survival in patients with acute STEMI after OHCA. METHODS: In this prospective study, from April 1, 2002 up to August 31, 2004, a total of 26 hospitalized individuals (22 men, 4 women, aged 35-79 years, median 58.5) from the East Bohemian region with OHCA (primary group of 718 individuals) with acute STEMI were included. Urgent coronary angiography was performed in 20 individuals, and direct PCI was done in 19 of them. The remaining 6 patients did not undergo angiography. RESULTS: Fifteen patients (57.7%) survived acute hospitalization, of whom 11 were without neurological deficits. In the subgroup with urgent coronary angiography 14 patients (70%) survived hospitalization, and in the subgroup without coronarography only 1 patient survived hospitalization (16.7%). In the subgroup with PCIs, 13 out of the 19 patients survived (68.4%). None of the patients died during the 1-year follow-up after being discharged from acute hospitalization. According to the urgent coronarography the artery most commonly responsible for the infarction was the left anterior descending artery (50%). Initial TIMI flow grade 0-I was found in 17 patients and grade II-III in 3 individuals. After PCI, irrespective of stent implantation, an optimal angiographic success (TIMI flow grade II-III) was obtained in 17 cases. CONCLUSION: Short-term survival of patients after OHCA with STEMI treated with direct PCI was found to be 68.4%. Out of 6 patients not receiving reperfusion therapy 1 survived (16.7%). Over the course of the 1-year follow-up none of the patients died.
