Effect of Danhong injection on prognosis and inflammatory factor expression in patients with acute coronary syndrome during the perioperative period of percutaneous coronary intervention: A systematic review and meta-analysis

Abstract

ObjectivesIn China, Danhong injection (DHI) is recommended by expert consensus and is widely used in the perioperative management of patients with acute coronary syndrome (ACS). This study investigates the effect of perioperative DHI administration and the timing of DHI administration on patients with ACS undergoing percutaneous coronary intervention (PCI) by analyzing the prognosis and anti-inflammatory effects. This article summarizes the most up-to-date clinical evidence on DHI, and in this study, we assesses treatment efficacy of DHI in patients with ACS.MethodsA total of seven databases (PubMed, Embase, Cochrane Library, SINOMED, CNKI, Wanfang, and VIP) were searched from the time of their inception to 1 July 2022. Clinical randomized controlled trials (RCTs) of DHI combined with PCI for the treatment of ACS were included. RCT quality was assessed using the Cochrane Handbook risk-of-bias tool, and STATA 17.0 was used for meta-analysis.ResultsIn total, 33 studies including 3,458 patients with ACS undergoing PCI were included in the meta-analysis. Compared with conventional therapy alone, the combination of DHI and conventional therapy significantly decreased the incidence of major adverse cardiovascular events (MACEs; P<0.001) and improved the reperfusion rate (P < 0.001). Serum high-sensitivity C-reactive protein (hs-CRP) and interleukin (IL)-6 levels were substantially reduced in the test group (P<0.001). In addition, the plasma levels of myocardial injury markers and cardiac troponin T (cTnT) declined significantly (P < 0.01). Compared with the control group, DHI improved the left ventricular ejection fraction (LVEF; P < 0.001) and reduced B-type natriuretic peptide (BNP; P < 0.001) levels. Subgroups were established based on different timings of DHI administration: preoperative, intraoperative, and postoperative groups. The results showed that the incidence of MACEs and the reperfusion rate did not differ between the groups. Among the subgroups, the postoperative group exhibited significantly lower levels of BNP, hs-CRP, and IL-6 serum and a significantly higher level of LVEF (P < 0.05).ConclusionThe combination of DHI and conventional therapy results in a better therapeutic effect than that observed with conventional therapy alone in patients with ACS. To improve treatment efficacy, postoperative initiation of DHI is recommended as a standard treatment. Further research is needed to confirm these results.Systematic review registrationIdentifier: CRD42022344830.
