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 2002-2005 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.
