title: [Effects of on-pump beating-heart coronary artery bypass grafting for left-main patients].
abstract: OBJECTIVE
  To explore the value of on-pump beating-heart coronary artery bypass grafting (OnP-BH CABG) for left-main patients with coronary heart disease through a comparative study with conventional coronary artery bypass grafting (CCABG).
  
  
  METHODS
  The clinical data were retrospectively analyzed for 66 patients of OnP-BH and 48 control cases undergoing CCABG from January 2009 to January 2012 at Department of Cardiac Surgery, People's Hospital of Zhengzhou University.
  
  
  RESULTS
  OnP-BH group had a better clinical outcome than CCABG group. There were obvious statistical difference in cardiopulmonary bypass (CPB) time, mean ventilation time, intensive care unit stay and recovery time of plasma cardiac troponin I (OnP-BH group vs CCABG group:(89 ± 25) vs (117 ± 28) min, (15 ± 14) vs (27 ± 19) h, (57 ± 27) vs (79 ± 34) h, (6.2 ± 1.8) vs (7.0 ± 2.4) d, all P < 0.05). The data of preoperative cTnI showed no significant difference between two groups (P > 0.05) .However, after CPB, significant intergroup difference existed in the level of cTnI (µg/L) OnP-BH group vs CCABG group: (0.5 h after CPB: (0.132 ± 0.022) vs (0.265 ± 0.014) , 1 h after CPB: (0.341 ± 0.027) vs (0.572 ± 0.046) , 1 h after operation: (0.641 ± 0.036) vs (0.932 ± 0.047) , 6 h after operation: (1.212 ± 0.765) vs (1.627 ± 0.542) and 24 h after operation: (1.496 ± 0.263) vs (1.734 ± 0.328) , all P < 0.05).
  
  
  CONCLUSIONS
  On-pump beating-heart coronary artery bypass grafting is a feasible surgical approach for left-main patients. And it has a low risk and causes less myocardial damage.
