Non-st-segment Elevation Acute Coronary Syndromes - Percutaneous Coronary Interventions in the First, Second and Third Day since the Onset of Symptoms

This paper describes the in-hospital outcome of urgent percutaneous coronary interventions (PCI) with delayed PCI in patients suffering from non-ST-segment elevation acute coronary syndromes (NSTE-ACS). The time when the PCI should be performed is still under debate. Results from 620 patients hospitalized in Silesian Centre of Heart Diseases in Zabrze in years 20022005 were included in this study for analysis. Patients were divided into two groups: group I – patients with urgent PCI and group II – patients with delayed PCI. The frequency of Thrombolysis In Myocardial Infarction grade 3 flow (TIMI 3) before PCI was significantly higher achieved in the second group (36.67% vs. 50.78%, p=0.05). Patients from group II had significantly more often TIMI 3 flow after PCI (82.72% vs. 92.55%, p=0.00036). The angiographic success evaluated as TIMI 3 flow after PCI occurred significantly more frequent in patients with delayed PCI than in patients with urgent PCI.
