title: [Percutaneous coronary intervention in acute coronary syndrome: single center experience from 4670 patients].
abstract: OBJECTIVE
  To explore the in-hospital effect of percutaneous coronary intervention (PCI) on patients with acute coronary syndrome (ACS).
  
  
  METHODS
  The clinical data of 4670 hospitalized patients with ACS, 1750 with acute myocardial infarction (AMI, 37.5%) within 30 days and 2920 with unstable angina pectoris (62.5%), undergoing PCI from August 1989 to October 2004, were analyzed.
  
  
  RESULTS
  The total success rate of PCI procedure was 98.1% (4579/4670) for all patients, and the patency rate of infarction related artery of emergency PCI was 98.2% (825/840) in the patients with AMI onset within 24 h. The complication rate related to PCI procedure was 6.5% (304/4670). The total in-hospital mortality was 1.1% (52/4670) and the mortality during PCI procedure was 0.04% (2/4670). The duration from admission to PCI was 3.5 days +/- 2.1 days and the whole hospital stay was 12 days +/- 8 days.
  
  
  CONCLUSIONS
  The success rate of PCI procedure in patients with ACS is high, while the in-hospital mortality and the complication rates are low, which shows that PCI has an ideal short-term effect in patients with ACS.
