[Epidemiologic importance of acute coronary syndrome in the population of the city of Zagreb].
OBJECTIVE
The aim of the study was to determine the number of hospitalized patients with acute coronary syndrome (ACS) in the Zagreb population.


METHODS
Zagreb residents hospitalized in five Zagreb hospitals (Sveti Duh General Hospital, Merkur, Sestre Milosrdnice, Dubrava University Hospitals, and Zagreb University Hospital Center) during 2000 and 2001 with the diagnosis of ACS, were examined. Patients who suffered from acute myocardial infarction with ST elevation (STEMI), patients with acute myocardial infarction without ST elevation (NSTEMI) and patients with unstable angina (UA) were analyzed according to gender and outcome.


RESULTS
During 2000, and 2001, 1453 and 1538 Zagreb residents were hospitalized for ACS, respectively, 62% of them men. STEMI was present in 54% of patients hospitalized during 2000 and 56% of those hospitalized during 2001. NSTEMI was present in 19% of patients in 2000 and 23% of patients in 2001, while the respective percentage of UA was 17% and 21%. Among STEMI patients, case fatality was higher in women (> 20%) than in men (< 20%) (p = 0.05), whereas no sex difference was observed in NSTEMI (< 20%) and in UA (about 3%) patients.


CONCLUSIONS
Women had a higher case fatality. Case fatality was also higher in patients with STEMI than in those with NSTEMI and UA, who had a much lower case fatality. Due to the lack of data, further follow-up is needed because reliable data can help us in the prevention and treatment of ACS.
