AB  - OBJECTIVE: To analyze the characteristics of the electrocardiogram (ECG) of left 
      anterior descending coronary artery (LAD) occlusion in patients with acute ST 
      elevation myocardial infarction (STEMI). METHODS: Patients included were those 
      diagnosed with STEMI in Peking Union Medical College Hospital from January 1996 
      to March 2009, and underwent coronary angiography (CAG). The infarction related 
      artery (IRA) was LAD, and there were no significant stenosis in left circumflex 
      artery and right coronary artery. A total of 170 cases were consecutively 
      enrolled. They were divided into 2 groups according to occlusive sites of the 
      LAD: LAD proximal (n = 77), LAD medius distal group (n = 93). Standard 18 leads 
      ECG within 12 hours from the onset of STEMI were recorded and ST segment 
      deviation was analyzed quantitatively. RESULTS: Proximal LAD occlusion as IRA was 
      diagnosed with aVL >/= 0.1 mV, ST aVL > aVR, sum of II, III and aVF STsegment 
      depression >/= 0.1 mV, in which sensitivity was 39.0%, 37.7% and 50.6%, specificity 
      was 78.5%, 77.4% and 74.2% respectively. Statisticully significance (P < 0.05). 
      Medius-distal LAD occlusion as IRA was diagnosed with no II ST depression, aVF ST 
      depression and sum of II, III and aVF ST segment depression > 0.1 mV, In which 
      sensitivity were 86.0%, 81.7% and 74.2% and the were 31.2%, 48.1% and 50.6% 
      respectively. Statisticully significance (P < 0.05). CONCLUSION: In STEMI 
      patients with isolated LAD occlusion, ECG can be useful to predict the occlusion 
      site.
