Efficacy and safety of Panax notoginseng saponin injection in the treatment of acute myocardial infarction: a systematic review and meta-analysis of randomized controlled trials
Abstract
Purpose: This study aimed to assess the efficacy and safety of Panax notoginseng saponin (PNS) injection, when combined with conventional treatment (CT), for acute myocardial infarction (AMI). Methods: Comprehensive searches were conducted in seven databases from inception until 28 September 2023. The search aimed to identify relevant randomized controlled trials (RCTs) focusing on PNS injection in the context of AMI. This meta-analysis adhered to the PRISMA 2020 guidelines, and its protocol was registered with PROSPERO (number: CRD42023480131). Result: Twenty RCTs involving 1,881 patients were included. The meta-analysis revealed that PNS injection, used adjunctively with CT, significantly improved treatment outcomes compared to CT alone, as evidenced by the following points: (1) enhanced total effective rate [OR = 3.09, p < 0.05]; (2) decreased incidence of major adverse cardiac events [OR = 0.32, p < 0.05]; (3) reduction in myocardial infarct size [MD = -6.53, p < 0.05]; (4) lower ST segment elevation amplitude [MD = -0.48, p < 0.05]; (5) mitigated myocardial injury as indicated by decreased levels of creatine kinase isoenzymes [MD = -11.19, p < 0.05], cardiac troponin T [MD = -3.01, p < 0.05], and cardiac troponin I [MD = -10.72, p < 0.05]; (6) enhanced cardiac function, reflected in improved brain natriuretic peptide [MD = -91.57, p < 0.05], left ventricular ejection fraction [MD = 5.91, p < 0.05], left ventricular end-diastolic dimension [MD = -3.08, p < 0.05], and…
