Abstract Background MicroRNA (miRNA) plays a critical function in the progression of acute coronary syndrome (ACS) and is associated with major adverse cardiovascular events (MACEs) after undergoing percutaneous coronary intervention (PCI). This research was designed to probe the diagnostic accuracy of miR-483-5p in patients with ACS and its predictive value of MACEs. Methods 118 patients with ACS (40 with unstable angina pectoris [UAP] and 78 with acute myocardial infarction [AMI]) and 75 healthy controls were enrolled. Serum miR-483-5p was detected in the subjects by reverse transcription-quantitative real-time PCR (RT-qPCR). ROC curve and logistic regression models were employed to estimate the diagnosis. Patients were monitored for 6 months after PCI to document the occurrence of MACEs. Kaplan-Meier survival was conducted to explore the predictive significance of miR-483-5p for the MACEs. Results Serum miR-483-5p levels were higher in ACS patients and associated with SYNTAX score and Gensini score. miR-483-5p was effective in identifying ACS patients from healthy individuals (AUC = 0.919) and AMI patients from ACS patients (AUC = 0.867), demonstrating a high diagnostic value, proven by logistic regression (OR = 9.664, 95%CI = 4.462–20.928, P < 0.001). The prevalence of MACEs during follow-up were 24.58%, and a higher prevalence of MACEs were observed in patients with elevated miR-483-5p (P = 0.01). miR-483-5p was also an effective predictor of MACE occurrence (HR = 5.955, 95%CI = 1.928–18.389, P = 0.002). Conclusion Expression of serum miR-483-5p can be utilized as a non-invasive marker for diagnosing ACS and predicting the onset of MACE after PCI.
