[Prospective register of primary percutaneous coronary interventions in patients with acute myocardial infarction].
The present study has evaluated the immediate angiographic results of primary percutaneous interventions (PCI) in patients with acute myocardial infarction, as well as hospital and 6-month clinical outcomes. The analysis covered a total of 265 patients (females (23%) and males (77%)); their mean age was 57+/-11 years. The mean time before the first balloon dilatation during PCI was 278+/-135 minutes after the development of the pain syndrome or 109+/-94 minutes after hospital admission. PCI proved to be effective in 96% of the patients, as evidenced by angiography. TIMI 3 blood flow was achieved in 83% of cases during PCI. After primary PCI, hospital mortality was 98.9% and 95% survived 6 months. At 6-month follow-up, 22% patients had positive exercise tests, recurrent angina pectoris and/or more than 50% luminal stenosis of the infarct-related artery. Control angiography made less than 6 months later showed 11% restenosis. This prospective study has demonstrated the high immediate and long effectiveness and safety of primary interventions in acute myocardial infarction.
