title: [Clinical analysis of acute coronary infarction patients with roughly normal coronary arteriographic findings].
abstract: OBJECTIVE
  To investigate the detection rate and possible causes of acute coronary infarction (AMI) patients with roughly normal coronary arteriographic (CAG) findings.
  
  
  METHODS
  A retrospective analysis was conducted in 311 cases of AMI undergoing CAG examination.
  
  
  RESULTS
  Of these 311 patients, 16 patients, whose age averaged 47.6 years, had roughly normal findings in CAG, including 9 below the age of 45 years, 10 with smoking history, and 5 with successful thrombolysis.
  
  
  CONCLUSIONS
  Patients with normal or roughly normal CAG finding might also have AMI likely induced by coronary artery thrombosis and spasm.
