Application of bivalirudin in coronary artery bypass grafting for patients with acute coronary syndrome
To explore the application effect of bivalirudin in patients with acute coronary syndrome undergoing coronary artery bypass grafting (CABG).
Methods
2
A total of 180 patients who underwent CABG for acute coronary syndrome at our hospital from May 2023 to May 2024 were enrolled and randomly assigned to the control group (received aspirin and unfractionated heparin) and the observation group (received aspirin combined with bivalirudin), with 90 cases in each group. A comparison was conducted between the two groups regarding myocardial perfusion parameters, cardiac function parameters, blood flow recovery status, endothelial function index, levels of inflammatory factors, and incidence of postoperative adverse reactions.
Results
2
The observation group had a significantly lower proportion of TIMI flow grade 2 and a higher proportion of grade 3 compared to the control group (
P
<
0.05). The left ventricular end diastolic diameter (LVEDD),left ventricular end diastolic volume (LVEDV),and levels of endothelin-1 (ET-1),hypersensitive C-reactive protein (hs-CRP),and tumor necrosis factor-α(TNF-α)after treatment in the observation group were smaller/lower than those before treatment and in the control group (
P
<
0.05). The left ventricular ejection fraction (LVEF),cardiac index (CI),and levels of nitric oxide (NO),and nitric oxide synthase (NOS)after treatment in the observation group were greater/higher than those in the control group and before treatment (
P
<
0.05). The proportion of patients with slow or no reperfusion and the incidence of adverse drug reactions during treatment in the observation group were significantly lower than those in the control group (
P
<
0.05).
Conclusion
2
For patients undergoing CABG for acute coronary syndrome,the combination of aspirin and bivalirudin significantly promotes cardiac perfusion,improves cardiac function indicators, reduces vascular endothelial injury,and demonstrates a high safety.
