Background: Lipoprotein a (Lp(a)) is an independent risk factor for adverse cardiovascular events in patients with acute myocardial infarction (AMI) and is closely related to cardiac remodeling after AMI. Objective: The purpose of this study was to investigate the relationship between Lp(a) and ventricular remodeling after percutaneous coronary intervention (PCI) in patients with acute anterior ST-elevation myocardial infarction (STEMI) and its predictive value after myocardial infarction. Methods: A total of 218 patients with anterior STEMI undergoing coronary intervention in our hospital were enrolled in our hospital, and left ventricular function and volume were evaluated by cardiac ultrasound at 1 week and 6 months after myocardial infarction. Poor ventricular remodeling (VR) is defined as a ≥ 20% increase in left ventricular end-diastolic volume 6 months after myocardial infarction. According to the left ventricular remodeling, the patients were divided into ventricular remodeling group and non-ventricular remodeling group. The Lp(a) and clinical data of the two groups were compared, and the multivariate logistic regression method was used to analyze the relevant factors affecting left ventricular remodeling after PCI in patients with anterior STEMI. The receiver operating characteristic curve (ROC) was created for independent risk factors, and the predictive value of Lp(a) in ventricular remodeling after myocardial infarction was analyzed.
