INTRODUCTION: Primary coronary angioplasty is at present a fully accepted and worldwide method of treatment of acute myocardial infarction. As proved by a number of randomized studies, this treatment is associated with a higher rate of coronary patency, a smaller infarction focus an better clinical results as compared with thrombolytic treatment.

METHOD: The authors analyzed a register of 233 consecutively treated patients with primary coronary angioplasty in the Faculty Hospital in Hradec Králové with elevation of the ST sections on electrocardiographic examination during the period from September 1997-January 2001.

RESULTS: Acute success defined as a residual stenosis < 30%, normal flow through the vessel (TIMI III) and survival for the first 24 hours was 91.0% and without patients with cardiogenic shock even 96.0%. The total mortality on hospitalization was 9.1%. The mortality of patients without cardiogenic shock was only 1.9%. A high mortality was recorded in patients in cardiogenic shock (74.0%). A stent was implanted in 65.0% patients, subacute thrombosis of the stent occurred in 1.9%. During a 6-month follow up the total mortality was 10.3%. The percentage of patients without any cardiovascular even (event free survival, EFS) after discharge from hospital was 81.0%.

CONCLUSIONS: The authors provided evidence that primary coronary angiolpasty is a safe and highly effective method in the treatment of acute myocardial infarction. It is associated with a total hospitalization mortality of ca 10% and a mortality of less than 2% in patients without cardiogenic shock. Cardiogenic shock, on the other hand, remains a problem despite intensive treatment such as inotropic support, mechanical reperfusion and intraortal balloon counterpulsation. In the presented work the mortality of patients with cardiogenic shock was 74.1%. Implantation of a stent does not involve a major risk for the patient, the incidence of subacute thrombosis of the stent is low and does not differ from elective procedures. The fate of patients during the follow up after primary angioplasty is favourable. In the presented work the total 6-month mortality was 10.3% and EFS was 81.0%.
