Abstract
Objective To explore the predictors of reperfusion arrhythmia (RA) after PCI in patients with acute myocardial infarction (AMI) using Meta-analysis, and to provide evidence for clinical diagnosis and treatment of RA. Methods Firstly, the inclusion and exclusion criteria were restricted and the search strategy was planned. The clinical trials that related to emergency PCI treatment in AMI patients and published before 31st December 2016 were included by two researchers in this study by searching PubMed, CINAHL Database, MEDLINE, Web of Science, Cochrane Libraray, CBM, VIP, CNKI and Wanfang Database. After evaluating the quality of the literature, the Review Manager 5.3 software was used for Meta-analysis. Results A total of 10 studies including 13 923 participants were enrolled. The Meta-analysis showed that the risk factors for RA after PCI in AMI patients included: smoking (OR=1.73; 95%CI 1.17-2.56; P 1 h (OR=4.03; 95%CI 1.60-10.15; P 1 (OR=2.22; 95%CI 0.90-5.48; P=0.08) . Conclusions The risk factors for RA after PCI in AMI patients include smoking, TIMI0 flow grade, inferior MI, right coronary artery infarction, multi-vasculopathy, renal failure, time from symptom onset to PCI ≤6 h, and duration of operation >1 h. The hypertension history and pre-infarction angina are protective against RA after PCI in AMI patients.
