AB  - OBJECTIVE: This study aimed to determine the association of a prominent Q wave in 
      lead (-)aVR with clinical, echocardiographic and angiographic findings in 
      anterior ST elevation myocardial infarction (STEMI) and to evaluate the role of 
      this finding in short-term and long-term outcomes. METHODS: During a one-year 
      period, 150 patients with first time anterior STEMI were screened and 121 
      patients with no other cardiopulmonary and renal comorbid diagnoses were included 
      in the study. Patients were allocated into two groups based on presence or 
      absence of a prominent Q wave in lead (-)aVR. All clinical, electrocardiographic, 
      echocardiographic and angiographic data were recorded and compared between the 
      groups. In-hospital adverse outcomes and mortality as well as two-year survival 
      were also compared. RESULTS: Among 121 patients (mean age: 62.8+/-12.5 years) 26.4% 
      had a prominent Q wave in lead (-)aVR. The prevalence of multi-vessel disease was 
      higher in patients with a Q wave (76.9% vs. 52.8%, p=0.03). ST-segment elevation 
      in lead V6 was significantly more common in those with a Q wave (50% vs. 30.3%, 
      p=0.04). Posterobasal region motion abnormality was more common in the Q wave 
      group. (9.4% vs. 1.2% respectively, p=0.04). Overall, mortality was higher in the 
      Q wave group; however, it was not statistically significant (15.4% vs. 9.3%, 
      p=0.39). CONCLUSION: In anterior STEMI, presence of a Q wave in lead (-)aVR is 
      associated with occlusion of multiple arteries. Short- and mid-term mortality are 
      not affected by this ECG finding.
