Background: The aim of this research is to further evaluate the efficacy and safety of percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) complicated with chronic renal insufficiency (CRI) by meta-analysis, to provide scientific and effective medical evidence for PCI in patients with AMI complicated with CRI, and to support the clinical application of PCI.
Methods: Electronic databases will be searched, including PubMed, Cochrane Library, Embase, CNKI, CBM, VIP, and Wanfang Data. Patients with AMI complicated by renal insufficiency treated with PCI will be included. The retrieval time is from inception to January 2019. The inclusion and exclusion criteria are formulated to search only the relevant literature. Endnote software management for literature will be adopted. The literature will be independently screened by 2 researchers. Excel 2016 will be applied to extract literature data with the "Research Information Registration Form." The final selected literature will be assessed for bias risk. Stata 12.0 software will be used for the meta-analysis.
Results: The systematic evaluation and meta-analysis will be carried out strictly in accordance with the requirements of the Cochrane System Evaluator Manual 5.3 on meta-analyses, which will provide a high-quality evaluation of the clinical efficacy and safety of PCI in patients with AMI and CRI.
Ethics and dissemination: This study belongs to the category of systematic reviews, not clinical trials. Therefore, it does not require ethical approval. The results of this study will be published in influential international academic journals related to this topic.
Conclusion: PCI is an effective and safe treatment for patients with AMI and CRI. This study will provide a definite evidence-based medical conclusion and provide a scientific basis for the clinical treatment of patients with AMI and CRI.
