Summary

This study aims to investigate the clinical characteristics and underlying mechanisms of acute myocardial infarction (AMI) in patients without traditional cardiovascular risk factors, such as hypertension, diabetes, dyslipidemia, or smoking history. By analyzing clinical data, imaging findings, and biomarkers, the research seeks to identify novel risk factors and mechanisms contributing to the pathogenesis of AMI in this unique population. The findings are expected to provide insights into improving diagnostic strategies and developing

Detailed description

Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide, primarily associated with well-established cardiovascular risk factors such as hypertension, diabetes, dyslipidemia, smoking, and obesity. However, a subset of AMI patients present without these traditional risk factors, posing a diagnostic and therapeutic challenge. This study focuses on the clinical characteristics, pathophysiological mechanisms, and potential novel risk factors associated with AMI in patients who lack conventional cardiovascular risk profiles. The study will be conducted as a single-center observational analysis involving patients diagnosed with AMI but without a history of hypertension, diabetes, dyslipidemia, smoking, or significant family history of coronary artery disease. Key objectives include: Characterizing Clinical Features: Analyzing demographic, clinical, and imaging data to identify patterns unique to this patient population. Identifying Biomarkers: Exploring circulating biomarkers, including inflammatory markers, genetic predispositions, and coagulation abnormalities, that may contribute to AMI development. Understanding Mechanisms: Investigating potential mechanisms such as microvascular dysfunction, endothelial injury, and autoimmune or hypercoagulable states. The study will utilize advanced imaging techniques, including coronary computed tomography angiography (CTA) and cardiac magnetic resonance imaging (CMR), to assess coronary anatomy and myocardial tissue characteristics. Genomic and proteomic analyses will be performed to identify genetic and molecular contributors. By elucidating the clinical and mechanistic profile of AMI in this unique population, the research aims to enhance the understanding of nontraditional pathways leading to AMI. These findings will pave the way for improved diagnostic tools, risk stratification models, and novel therapeutic interventions tailored to this underexplored patient group.
