title: Multivessel percutaneous coronary intervention in Chinese patients with acute myocardial infarction and simple nonculprit arteries.
abstract: BACKGROUND
  Multivessel percutaneous coronary intervention (PCI) for patients during acute myocardial infarction (AMI) is currently controversial. In this study, we investigated the significance of multivessel PCI in Chinese patients with ST-segment elevation AMI and relatively simple lesions in nonculprit arteries.
  
  
  METHODS
  We reviewed all consecutive primary PCI of ST-segment elevation AMI in our hospital between 2002 and 2005. The patients with multivessel disease and ACC/AHA type A/B1 lesions in nonculprit arteries who underwent multivessel PCI were identified (n = 105, multivessel PCI group), and 120 patients with single-vessel disease and treatment with primary PCI were enrolled as control subjects (single-vessel PCI group). The primary end points were the occurrences of 6-month major adverse cardiac events (cardiogenic death, nonfatal reinfarction, and target vessel revascularization). The secondary end points included procedure time, angiographic success rate, TIMI grade, reperfusion arrhythmia, ST-segment resolution, and left ventricular ejection fraction.
  
  
  RESULTS
  All patients with multivessel PCI tolerated the operations well and had similar TIMI 3 and angiographic success rates but longer procedure times than those patients with single-vessel PCI. There were no significant differences in reperfusion arrhythmia, ST-segment resolution, left ventricular ejection fraction, or 6-month MACEs between both groups.
  
  
  CONCLUSIONS
  This study suggests that multivessel PCI is effective and safe for Chinese patients with ST-segment elevation AMI and simple lesions in nonculprit arteries.
