title: [Comparative analysis of the risk factor on the clinical information of myocardial revascularization combined with concomitant valve operations].
abstract: OBJECTIVE
  To evaluate the clinic information of coronary artery bypass grafting (CABG) combined with concomitant valve operation.
  
  
  METHODS
  Retrospectively analyze the information of morbidity and mortality of 126 cases patients who underwent combined valve and bypass procedures between December 2000 and January 2005. These patients had been divided into 2 groups according to sex.
  
  
  RESULTS
  There were significant differences in the clinic characteristic such as weight and diabetes mellitus and mitral valve stenosis and three disease vessels of coronary artery between 2 groups (P < 0.05). The rate of the number of bypass grafts and morbidity and mortality of complication were significant differences (P < 0.05). The number of mitral valve replacement of female was more than that of male (P < 0.05). Five males died after operation, 1 case of heart failure, 1 case of high blood sugar, 2 cases of arrhythmia, 2 cases of organs failure; Seven females died after operation, one case of heart failure, one case of alimentary tract haemorrhage, three cases of arrhythmia, two cases of organs failure.
  
  
  CONCLUSIONS
  Coronary artery bypass grafting (CABG) combined with concomitant valve operation is safe and effective. The rate of morbidity and mortality of complication of female is more than that of male. The study demonstrates that female gender is an independent risk factor for combined morbidity and mortality during and after combined valve and coronary bypass surgery. That is related to low weight and mitral valve stenosis of female.
