[Abstract]
Objective To investigate the effects of papaverine combined with bivarutin administrated by intracoronary injection on serum myocardial injury markers, high mobility group box-1(HMGB1), endothelin-1(ET-1), transforming growth factor β1 (TGF-β1)and short-term prognosis in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary intervention (PCI). Methods The clinical data of 90 patients with slow flow/no reflow STEMI during emergency PCI admitted to the Xinxiang First People's Hospital from January 2018 to December 2021 were analyzed retrospectively. They were divided into control group and experimental group according to different treatment schemes, with 45 patients in each group. Coronary angiography and PCI were performed routinely in both groups, and stents were implanted after balloon pre dilation. In case of slow blood flow/no reflow, 0.375 mg·kg-1 of Bivarutin for Injection was injected into the coronary artery in the control group, and the Papaverine Hydrochloride Injection was injected into the coronary artery in the experimental group on the basis of the control group, 3-5 mg per time, 3 mg per time for body weight below 60 kg, and 5 mg per time for body weight above 60 kg. If there was no reflow, it was repeated once within 3 to 5 minutes, 2 to 3 times, and the total dose was ≤ 20 mg. The proportion of patients with TIMI blood flow grade 3, corrected TIMI blood flow frames (cTFC), and the complete ST segment fall rate 24 hours after operation were compared between the two groups. Serum myocardial injury markers[creatine kinase isoenzyme (CK-MB), troponin I (cTnI)], HMGB1, ET-1 and TGF-β1 were detected before PCI and 24 hours and seven days after PCI. The adverse cardiovascular and cerebrovascular events and clinical bleeding events in the two groups were counted within one month after operation. Results The percentage of patients with TIMI grade 3 immediately after operation and the rate of complete ST segment regression 24 hours after operation in the experimental group were significantly higher than those in the control group (P<0.05). The cTFC immediately after operation was significantly lower than that in the control group (P<0.05). The levels of serum CK-MB and cTnI in the two groups at 24 hours after operation were significantly higher than those before operation (P<0.05), and at seven days after operation were significantly lower than those at 24 hours after operation (P<0.05). The levels of serum CK-MB and cTnI in the experimental group were significantly lower than those in the control group at 24 hours and 7 days after operation (P<0.05). The levels of serum HMGB1, ET-1 and TGF-β1 24 h after operation in both groups were significantly higher than that before operation (P<0.05), and at seven days after operation they were significantly lower than that of 24 hours after operation (P<0.05). In the experimental group, the levels of serum HMGB1, ET-1 and TGF-β1 at 24 h and 7 d after operation were significantly lower than that of the control group at the same time point (P<0.05). Within one month after operation, the incidence of adverse cardiovascular and cerebrovascular events in the experimental group was significantly lower than that in the control group (4.44% vs 17.78%, P<0.05). There was no significant difference in the incidence of clinical bleeding events between the two groups (15.56% vs 13.33%, P>0.05). Conclusion The combined use of papaverine and bivalirudin in the coronary artery for the treatment of slow/no reflow during emergency PCI can effectively improve the coronary blood flow, reduce myocardial injury and endothelial injury, alleviate the inflammatory reaction of the body, and improve the short-term prognosis of patients.
