title: [Clinical and angiographic predicting factors leading to unfavorable myocardial reperfusion in patients with acute ST-elevation myocardial infarction after primary percutaneous coronary intervention].
abstract: OBJECTIVE
  To investigate the clinical and angiographic morphologic features leading to worse myocardial reperfusion in patients with acute ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI).
  
  
  METHODS
  Clinical and angiographic data were collected and logistic regression analysis performed in 964 STEMI patients undergoing primary PCI.
  
  
  RESULTS
  Logistic regression analysis showed that non-anterior myocardial infarction, pain to balloon time and degree of cardiac dysfunction were clinical predictive factors while fade-out type of angiographic morphology, ie, presence of accumulated thrombus proximal to the occlusion was angiographic predictive factor of worse reperfusion for STEMI patients post PCI.
  
  
  CONCLUSIONS
  These predictive clinical and angiographic morphologic factors in STEMI patients for worse myocardial reperfusion post PCI could help to identify patients at high risk post PCI.
