Abstract:
Objective To study the clinical efficacy of Off-Pump Coronary Artery Bypass Grafting (OPCABG) in the patients who have left main coronary artery stenosis and three-vessel lesion with low ejection fraction.MethodsFrom January 2010 to December 2010,28 cases with low ejection fraction,left main coronary artery stenosis and three-vessel lesion and received OPCABG were analyzed retrospectively.All cases underwent OPCABG under general anesthesia.The Hb,PLT,ALT,AST,BUN and Cr count before and 3 days after operation were recorded.LVEF andLVEDbeforeand 3monthsafter operationwererecorded.Thedata were compared.Results one case died of respiratory failure caused by pulmonary infection.The mortality rate was 3.75 ％.The value of six parameters are: Hb ( [ 137.94 ± 19.40 ],[ 111.06 ± 12.71 ] g/L),PLT ( [ 210.43 ±48.26 ] × 109/L,[ 148.4 ± 52.20 ] × 109/L),ALT ( [ 27.66 ± 11.51 ] U/L,[ 29.02 ± 16.40 ] U/L),AST ([26.55 ± 10.12] U/L,[27.75 ±8.14] U/L),BUN([6.51 ± 1.00] mmol/L,[6.88 ± 2.53] mmol/L),Cr ([96.35 ± 15.25]μmol/L,[95.11 ± 24.38 ] μmol/L).Comparison of the values showed that Hgb and PLT were different significantly before and 3 days after operations.There was no significant difference in the levels of ALT,AST,BUN and Cr before and after the treatment.Three months later,LVEF and LVED were significantly different from that before treatment ( P ＜ 0.05 ),with LVEF of( [ 36.23 ± 3.41 ] ％,[ 47.23 ± 5.13 ] ％ ) and LVED of( [62.23 ±5.93]mm,[58.08 ±5.02] mm).ConclusionOPCABG produces a satisfactory outcome in the patients who have left main coronary artery stenosis and three-vessel lesion combined with low ejection fraction.There is limited impact of OPCABG on the other organs.The long-term effect and prognosis are still need to be followed-up and analyzed.
