This study seeks to investigate the clinical value of novel biomarkers and echocardiographic indices, including myocardial work parameters, in patients with first acute myocardial infarction. The relationship between novel echocardiographic indices with clinical data, biochemical data in different myocardial infarction types will be attempted. Prognostic implications of those indices will be explored.

This study is a prospective registry designed to evaluate and explore novel associations and prognostic tools in patients with first Acute Myocardial Infarction (AMI) with or without ST elevation, as defined by the Fourth Universal Definition of Myocardial Infarction. All eligible adult patients admitted to the Department of Cardiology at AHEPA University General Hospital of Thessaloniki with AMI will be invited to participate.

Following revascularization, a complete and comprehensive medical interview will be conducted for each patient, during which demographic characteristics, baseline medical history, medical therapy upon admission and discharge, primary aetiology, and clinical presentation of hospitalization will be recorded. Laboratory data will be collected on admission and during hospitalization, including complete blood count, biochemical control, coagulation mechanism control, hormonal control, lipid profile including Lp(a), HbA1c, N-terminal pro-B-type natriuretic peptide plasma, higher-peak value of HsTnT, IL-6, and suPAR levels on admission.

A comprehensive transthoracic echocardiographic assessment (TTE) will be performed within 24-48 hours from revascularization to evaluate the cardiac function of patients. The TTE will include 2-dimensional-speckle-tracking analysis of all cardiac chambers and non-invasive calculation of myocardial work of the left and right ventricles. The clinical value and prognostic implications of these echocardiographic indices will also be investigated during follow-up.

The primary objective is to identify novel prognostic tools by examining the association between echocardiographic indices, clinical, and biochemical data. The study aims to contribute to a better understanding of the pathophysiology of this condition and the development of effective management strategies. By comprehensively assessing the clinical, biochemical, and echocardiographic features of patients with AMI, this study will help to establish a foundation for developing targeted and effective treatments for AMI patients.
