Ociated with heart failure and increased mortality. The prognostic function of GSK9311 chemical information pre-treatment PAI-1 activity in individuals with AA and AMI, treated with STK was evaluated.Accessible on-line http://ccforum.com/supplements/6/SMethods: In sufferers with AMI, treated with streptokinase, pretreatment PAI-1 levels have been estimated by chromogenic approach (typical levels 0.five?.5 U/ml) plus the presence or absence of AA assessed. Integrated have been atrial fibrillation and/or flutter and/or tachycardias. We compared pre-treatment variables (PAI-1 included) and in-hospital events in individuals with PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20724923 and with out AA. Results: AA were discovered in 22.4 (26/116) of sufferers. Among pre-treatment variables, the only statistically considerable distinction amongst sufferers with and with out AA was observed in mean pretreatment PAI-1 levels (P = 0.0017). PAI-1 level more than 7 U/ml was one of the most important independent danger factor for AA (P < 0.05, OR 3.5,95 CI 1.15?0.6). AA were significantly associated with cardiogenic shock, pulmonary edema, cardiopulmonary resuscitation after STK, conduction disturbances and mortality. In-hospital mortality of patient with AA was 23 and 4 without them (OR 6.45, 95 CI 1.66?5.017). Among in-hospital events, cardiogenic shock was the most significant independent predictor of AA. Conclusions: AA in patients with AMI, treated with streptokinase, were associated with elevated mean pre-treatment PAI-1 levels and increased mortality due to heart failure. Pre-treatment PAI-1 over 7 U/ml was the only independent significant risk for AA during AMI.P153 Predictive role of plasminogen-activator-inhibitor-1 (PAI-1) in non-ST-segment elevation acute coronary syndromeA Sinkovic*, V Urlep-Salinovic *ICU, and Department for Transfusiology, General Hospital Maribor, Ljubljanska 5, 2000 Maribor, Slovenia Background: Increased plasma activity of plasminogen-activatorinhibitor-1 (PAI-1) is associated with increased risk for coronary thrombosis, but its role in predicting adverse events in non-STsegment elevation acute coronary syndrome (ACS) is not yet defined. Therefore, we studied prospectively the role of PAI-1 activity for the 30-days composite endpoint of death and new myocardial infarction (MI) in patients with ACS. Methods: Fifty-one patients with chest discomfort, but no STsegment elevation on ECG were admitted to the ICU. PAI-1 levels were estimated at admission and every 12 hours in the first 48 hours by chromogenic method (normal range 0.5?.5 U/ml), as well as Troponin T (TnT) by electrochemiluminescence immuno method at admission and 8 hours later (normal level up to 0.1 /l). After initial medical therapy, in case of recurrent ischemia and/or haemodynamic and/or rhythmic instability, percutaneous interventions (PCI) were performed. Thirty-days mortality and new MI were registered. Results: The composite 30-days endpoint of mortality and/or new MI was 13.1 (7/51). Between patients with and without composite death and/or new MI statistically significant difference was observed in mean admission PAI-1 levels (5.3 ?4.2 vs 3.0 ?2.4 U/ml, P < 0.05), highest mean PAI-1 levels in the first 48 hours (5.98 ?4.1 vs 3.2 ?2.4 U/ml, P < 0.05), mean ICU stay (7.8 ?7.0 vs 3.1 ?1.4 days, P < 0.001), but nonsignificant difference in mean admission TnT (0.5 ?0.7 vs 0.4 ?7.3 /l, P > 0.05) and highest in-hospital TnT levels (1.four ?1.eight vs 0.9 ?1.5 /l, P > 0.05). The danger for 30-days mortality and/or new MI was drastically increased only in sufferers with PAI-1 levels more than 5.0.
