AB  - OBJECTIVE: To explore the characteristics of ST-segment deviation in patients 
      with acute ST elevation myocardial infarction(STEMI)having only one vessel lesion 
      in either left circumflex artery (LCX) or right coronary artery (RCA). METHODS: 
      All AMI (acute myocardial infarction) patients were admitted into Peking Union 
      Medical College Hospital from January 1996 to March 2009. They underwent coronary 
      angiography (CAG). And the IRA (infarction-related artery) was either LCX or RCA 
      without other coronary artery stenosis. Their ST-segments deviations on 
      electrocardiogram (ECG) were analyzed quantitatively. RESULTS: Among 2503 AMI 
      cases undergoing CAG during hospitalization, 75 cases had LCX (n = 16) or RCA (n 
      = 59)-related STEMI. The RCA group was further divided into the proximal subgroup 
      (n = 21) and the distal subgroup (n = 38). RCA as IRA was diagnosed when ST I 
      depression < 0, ST V(1) elevation >/= 0 or ST I and aVL depression < 0 with the 
      sensitivities of 55.9%, 74.6% and 54.2% and the specificities of 81.3%, 62.5% and 
      81.3% respectively. LCX as IRA was diagnosed when ST aVR depression >/= 0.1 mv, ST 
      I elevation >/= 0 or ST V(5) and V(6) elevation >/= 0 with the sensitivities of 
      68.8%, 81.3% and 31.3% and the specificities of 76.3%, 59.3% and 91.5% 
      respectively. Proximal occlusion of RCA was diagnosed when there was no ST 
      depression in V(1) and depression in V(2), Max precordial ST depression in 
      V(1)-V(3) with the sensitivities of 47.6% and 52.4% and the specificities of 
      78.9% and 84.2%. CONCLUSION: While discriminating IRA in STEMI patients with 
      single LCX or RCA lesion, it is necessary to assess all ST-segments deviations on 
      ECG.
