TI  - Surgical revascularization of left main coronary artery stenosis: determinants of 
      perioperative and long-term outcome in the 1980s.
PG  - 440-6
AB  - The postoperative courses of 176 patients who underwent coronary artery bypass 
      surgery for significant left main coronary artery stenosis were analyzed to 
      determine which preoperative clinical and angiographic factors correlated best 
      with outcome. Clinical variables included age, sex, New York Heart Association 
      (NYHA) anginal class, presence of unstable angina, and surgical class. The 
      angiographic variables included percentage of left main stenosis, presence of 
      right coronary artery stenosis, coronary dominance, number of vessels diseased, 
      myocardial jeopardy score, and ejection fraction. The overall perioperative 
      mortality rate was 9.1%. There was a significant increase in perioperative 
      mortality among female patients (p less than 0.05) and patients undergoing 
      emergency surgery (p less than 0.05). Patients with left main stenosis of 80% or 
      more or with balanced or left dominant circulation showed trends toward increased 
      perioperative mortality. Life-table analysis showed that emergency surgery and 
      left main stenosis of 80% or more correlated with increased long-term mortality 
      (p less than 0.05). No other variable tested showed a significant correlation 
      with either perioperative or long-term mortality. A comparison of these results 
      with studies performed in the 1970s shows that there has been considerable change 
      in those factors which place a patient at increased risk for mortality during 
      surgical treatment of left main coronary artery stenosis.
