Abstract：Objective To investigate the risk factors for malignant ventricular arrhythmia(MVA)in patients with acute coronary syndrome(ACS)after percutaneous coronary intervention(PCI).Methods ACS patients(n=150)undergone PCI were chosen from Central Hospital of Xianyang City from July 2020 to July 2023.All patients were divided,according to whether MVA occurred after PCI or not,into observation group(n=42)and control group(n=108).The patients were followed up for 3 months.The clinical materials were compared between 2 groups,and risk factors affecting MVA occurrence were analyzed.Results The prognosis was poor in MAV patients after PCI.There were significant differences in average age,smoking,diabetes,coronary artery disease,time from disease onset to PCI,the number of stents,expression levels of brain natriuretic peptide(BNP),C-reactive protein(CRP),creatine kinase-MB isoenzyme(CK-MB)and white blood cell(WBC),and neutrophil count(NEUT)between 2 groups(P＜0.05).The results of Logistic analysis showed that complicated diabetes,time from disease onset to PCI≥6 h,multi-vessel lesions of coronary artery,and increased CRP and BNP were influence factors for MVA occurrence in ACS patients after PCI.Conclusion Complicated diabetes,time from disease onset to PCI≥6 h,multi-vessel lesions of coronary artery,and increased CRP and BNPcan affect MVA occurrence in ACS patients after PCI.In clinical practice,preventive measures and actively intervention should be strengthened to reducing MVAoccurrence and improving prognosis.
