The Relationship between Lipoprotein A and the Prevalence of Multivessel Coronary Artery Disease in Young Patients with Acute Myocardial Infarction: An Observational Study

Abstract

Introduction: Cardiovascular diseases are the leading cause of mortality worldwide, with a significant impact on socioeconomic aspects. Various biomarkers have been studied in relation to the diagnosis, progression, and prognosis of atherosclerotic disease, with lipoprotein (a) [Lp (a)] standing out as an important predictor of cardiovascular risk. This observational study aimed to clarify the association between Lp (a) levels and the severity of significant multivessel coronary lesions in acute myocardial infarction (AMI) patients. Materials and Methods: Conducted at the Clinical Emergency County Hospital of Craiova, Romania, the study involved 256 young patients divided into two groups based on Lp (a) levels: Group A (Lp (a) Results: The study revealed a significant association between elevated Lp (a) levels and the presence of multivessel coronary lesions. Patients with Lp (a) concentrations ≥ 30 mg/dL exhibited a higher prevalence of multivessel disease compared to those with lower levels. Discussion: The findings suggest that elevated Lp (a) levels are a crucial biomarker for the risk of coronary artery disease, particularly in young patients with AMI. The study emphasizes the need for aggressive lipid management strategies and personalized treatment approaches, considering the significant role of Lp (a) in atherosclerosis and AMI. Conclusions: Lipoprotein A levels above 30 mg/dL are associated with a higher prevalence of multivessel coronary lesions. Multivariate analysis revealed that higher Lp (a) levels and lower HDL levels are linked to an increased risk of multivessel coronary lesions.
