The acute coronary syndrome is a leading cause of heart death among adults. The treatment of such patients begins during the first contact with the doctor who is in most cases neither an internist or cardiologist, but an emergency medicine specialist or general practitioner working in the emergency department. For that reason it is of great importance to educate doctors who will be able to establish a fast and precise diagnosis, start therapy and organize quick transport to the nearest catheterization room or coronary unit.

The primary objective was to measure frequency of patient's visits to the Emergency Department because of an acute coronary syndrome. The Secondary objective was to examine the choice of treatment in pre-hospital conditions.

Through the statistical retrospective analysis we collected the data from the Emergency Department protocols for the period between June 1, 2008 and December 31, 2008.

In 14,986 patients during the six-month period, 343 of them had acute coronary syndrome. Men were more affected ((59.5%) than women (40.5%). Most cases belonged to the age group from 65 to 80 years (39.6%) and prevalence after 50 years shows abrupt growth. According to the diagnoses, most patients had unstable pectoral angina (42%) and then followed stenocardia (31%) and AIM (27%). Other therapy included NTG (22%), antihypertensives (21%), acetyl-salicylic acid (20%), analgesics (13%), antiarrhythmics (4%). Fifty-seven percent of the patients had complications. STEMI was diagnosed in 69% of patients, and most often the anterior wall was involved (35%).

The diagnosis of acute coronary syndrome was established in 343 patients based on the clinical image, electrocardiographic changes and level of cardiospecific enzymes (troponin T).
