Implementation of cardiac troponin (cTn) assays has revolutionized the diagnosis, risk stratification, triage and management of patients with suspected myocardial infarction (MI). The Universal Definition of MI brought about a shift in the diagnostics of MI, from an approach primarily based on electrocardiography (ECG) to one primarily based on biomarkers. Currently, detection of a rise and/or fall in concentration or activity of myocardial necrosis biomarkers, preferentially cTns, with at least one value above the 99th percentile upper reference limit (URL), is the essential component for the diagnosis of MI...

Current guidelines for the management of patients with acute coronary syndromes (ACSs) focus on the electrocardiogram to divide patients into ST-elevation acute myocardial infarction (STEMI) or non-ST-elevation acute myocardial infarction (NSTEMI)/unstable angina (UA). Patients with STEMI in the earliest time will receive reperfusion therapy to destruct occlusive thrombus. An ST segment elevation is the 'sine qua non' for diagnosing acute total coronary occlusion causing transmural myocardial infarction. Left circumflex coronary artery (LCx) occlusion is often categorized as NSTEMI because of the absence of significant ST-elevation on the 12 lead standard electrocardiogram...

INTRODUCTION: The most common classification of acute myocardial infarction (AMI) is based on electrocardiographic findings and distinguishes ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI). Both types of AMI differ concerning their epidemiology, clinical approach and early outcomes. Ticagrelor is a P2Y12 receptor inhibitor, constituting the first-line treatment for STEMI and NSTEMI. According to available data, STEMI may be associated with lower plasma concentration of ticagrelor in the first hours of AMI, but currently there are no studies directly comparing ticagrelor pharmacokinetics or antiplatelet effect in patients with STEMI versus NSTEMI...
