Clinical Efficacy Analysis of prophylactic intra-aortic Balloon Pump in high-risk coronary Heart Disease Patients undergoing coronary Artery Bypass Grafting
Objective To analyze the clinical efficacy of prophylactic intra-aortic balloon pump(IABP)before coronary artery bypass grafting in high-risk coronary heart disease.Methods A study was conducted on 62 high-risk coronary heart disease patients admitted to the First Affiliated Hospital of Nanyang Medical College from December 2020 to December 2022;According to the surgical conditions of the patients,they were divided into two groups(control group and experimental group,each with 31 cases),and both groups underwent coronary artery bypass grafting surgery.The timing for the placement of IABP in the control group is intraoperative or postoperative,while the timing for the placement of IABP in the experimental group is preoperative.The treatment efficacy,changes in cardiac function indicators before and after treatment,postoperative recovery indicators,and incidence of postoperative complications were compared between two groups.Results The effective rate of treatment in the experimental group(96.77%)was higher than that in the control group(80.65%),and the difference was statistically significant(P＜0.05).Before treatment,there was no statistically significant difference in cardiac function indicators between the two groups(P＞0.05);After treatment,the cardiac output(CO),stroke output(SV),and left ventricular ejection fraction(LVEF)of both groups were higher than those before treatment,while the left ventricular end systolic diameter(LVESD)and left ventricular end diastolic diameter(LVEDD)were lower than those before treatment.The CO,SV,and LVEF of the experimental group were higher than those of the control group,while LVESD and LVEDD were lower than those of the control group,and the difference was statistically significant(P＜0.05).The experimental group had shorter IPBP support time,mechanical ventilation maintenance time,ICU monitoring time,and total hospital stay compared to the control group,with statistically significant differences(P＜0.05);The incidence of postoperative complications in the experimental group(6.45%)was lower than that in the control group(29.03%),and the difference was statistically significant(P＜0.05).Conclusion The clinical efficacy of prophylactic placement of IABP in patients undergoing coronary artery bypass grafting for high-risk coronary heart disease is beneficial for improving prognosis.It has outstanding performance in postoperative rehabilitation and reducing postoperative complications,and is worthy of application.
