[Interventional treatment of myocardial infarction. Own experience].
The aim of the study is the analysis of own results of myocardial infarction treatment using percutaneous coronary intervention (PCI) in the setting of twenty-four hour long hemodynamic service. Between 01.12.1998 and 31.12.2001 249 patients with diagnosis of acute myocardial infarction were admitted to our Department. Their mean age was 58 years, men -73.5%, median of pain duration was 4 hours, diabetes occurred in 11.6%, hypertension in 37.3%, dyslipidemia occurred in 14%, smokers constituted 59% of patients. 60.2% of patients were in Killip class I, 18.5% in class II, 8.0% in class III and 13.3% in class IV. Anterior and/or lateral myocardial infarction was diagnosed in 105 patients, inferior and/or posterior in 144 patients. Angiography was performed in 225 patients, PCI was performed in 178. TIMI 3 flow was achieved in 76% of patients with shock and 90% of patients without shock. Multivessel coronary artery disease was present in 71% of patients. 30-day mortality in patients treated with PCI was 11.8%, after exclusion of III and IV Killip class patients mortality was 4.3%. 30-day mortality in group of patients with cardiogenic shock was 38.0%. Relative risk of death in patients in III and IV Killip class was higher for these treated conservatively: IV class -1.51 (p = 0.075), III and IV class (common group) -1.38 (p = 0.064). In the year of 2001 30-day mortality among the patients in I and II Killip class treated with PCI was 2.43%.


CONCLUSIONS
1. Primary percutaneous coronary intervention in the treatment of myocardial infarction improves prognosis in group of patients with cardiogenic shock in 30-day observation. 2. 11.8% mortality observed in our PCI treated group is associated in our opinion with occurrence of multivessel coronary disease in 71% of patients.
