The efficacy and safety of Shenfu injection in patients undergoing percutaneous coronary intervention for ST segment elevation myocardial infarction: A protocol for systematic review and meta-analysis

Shenfu injection is a traditional Chinese medicine formulation that alleviates ischemia–reperfusion injury through multiple pharmacologic effects. However, there is lack of evidence regarding its efficacy in myocardial infarction. We performed a protocol for systematic review and meta-analysis to evaluate the efficacy and safety of Shenfu injection for ST segment elevation myocardial infarction after primary percutaneous coronary intervention. METHODS: This review has been reported following the preferred reporting items for systematic reviews and meta-analyses protocol. A literature search was performed in November 2022 without restriction to regions, publication types, or languages. The primary sources were the electronic databases of PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure database, Chinese Biomedical Database, and Chinese Science and Technology Periodical database. Risk of bias will be assessed according to the Cochrane Risk of Bias Tool. Data analysis was performed using Reviewer Manager 5.4. RESULTS: The results of this systematic review will be published in a peer-reviewed journal. CONCLUSION: This systematic review will provide evidence to judge whether Shenfu injection is effective and safe in patients undergoing percutaneous coronary intervention for ST segment elevation myocardial infarction.
