The Study Of Primary Percutaneous Coronary Intervention On Non-ST-Segment Elevation Acute Coronary Syrdrome

ObjectiveThere have been many controversies on the value of percutaneous coronary intervention (PCI) in patients of non-ST-segment elevation ACS. In 1998, the study of VAWQWISH claimed that the mortality of the patients with non-ST-segment elevation ACS increased when treated with PCI. At the same time, some experts maintained that the patients should be treated with PCI after thrombolysis because plaque would be steady then. Recently, with the development of the techniques of PCI, such as coronary stenting, anticoagulation, and anti-platelet aggregation, some inspiring changes have been made. In 1999, the study of FRISCâ…¡stated that it was helpful to the patients of non-ST-segment elevation ACS who were treated with primary percutaneous coronary invention (PPCI), and the incidence of acute myocardial infarction (AMI) and mortality in 6 months and 12 months reduced by 22% and 26%. Furthermore, the study of RITA-3 suggested that the incidences of new-onset myocardial infarction and mortality in PPCI...
