TI  - Coronary artery bypass grafting in patients with left ventricular dysfunction.
PG  - 218-23
AB  - BACKGROUND: Coronary artery bypass grafting surgery (CABG) remains a challenge 
      for patients with coronary artery disease and left ventricular (LV) dysfunction. 
      The aim of this study was to evaluate the result of CABG in patients with LV 
      dysfunction. METHODS: Medical records of 1,847 patients who underwent primary, 
      isolated CABG at Taipei Veterans General Hospital from January 1, 1991 to 
      December 31, 2002, were reviewed. The mortality rate associated with clinical and 
      operative variables was compared between patients with LV ejection fraction 
      (LVEF) > or = 35% and patients with LVEF < 35%. RESULTS: Patients with LVEF < 35% 
      had more episodes of myocardial infarction (57.5% vs 28.9%, p < 0.001) and 
      history of congestive heart failure (18.1% vs 3.2%, p < 0.001), higher New York 
      Heart Association (NYHA) class, and higher angina class. Longer cardiopulmonary 
      bypass time (147 +/- 44 minutes vs 137 +/- 40 minutes, p < 0.001) but fewer left 
      internal mammary artery (LIMA) grafts (46.8% vs 65.7%, p < 0.001) were used in 
      patients with LVEF < 35%. Patients with LVEF < 35% had significantly higher 
      hospital mortality (6.6% vs 2.2%, p < 0.001), higher major morbidity (23.3% vs 
      16.1%, p < 0.01), and longer hospital stay (25 +/- 23 days vs 21 +/- 16 days, p < 
      0.01). CONCLUSION: Although patients with LV dysfunction had higher mortality and 
      morbidity, CABG could be done in these high-risk patients with acceptable 
      results.
