Clinical analysis of IABP assisted off-pump coronary artery bypass grafting in treatment of severe coronary heart disease

Abstract

Objective To investigate the clinical effects of intra-aortic balloon pump (IABP) assisted off-pump coronary artery bypass grafting (OPCABG) on severe coronary heart disease (CHD). Methods Eighty patients with severe CHD were randomly divided into two groups, with 40 cases in each group. The patients in control group were given OPCABG, while the patients in observation group were treated by IABP assisted OPCABG. The curative indexes, cardiac function and complications were compared between the two groups. Results The operation time, respirator supporting time, ICU hospital stays, postoperative thrombocytopenia, low cardiac output, conversion to on-pump and death rate in observation group were lower than those in control group (P<0.05). After surgery for 3 months, the left ventricular ejection fraction (LVEF) and left ventricular end-diastolic dimension (LVDD) in the two groups improved, and compared with control group, the LVEF level of the observation group was higher and LVDD level was lower (P<0.05). Conclusions IABP assisted OPCABG is effective on severe CHD, which can shorten curative time, improve the cardiac function, and reduce the complications and death rate.
