The use of serial measurement of cardiac troponin (cTn) is recommended by international guidelines for the diagnosis of myocardial infarction (MI) since 2000. This article focuses on factors influencing temporal changes in high-sensitive cTn (hs)-cTn and the impact of these factors on the diagnosis of non-ST-segment elevation MI (NSTEMI). The recommendations proposed by three different international guidelines published in 2020-2021 for the management of acute coronary syndromes (ACS) in patients presenting without persistent ST-segment elevation (NSTE) show some discrepancies. In particular, there is no agreement among these guidelines about cut-off or absolute change values to be used for the rule-in, especially regarding the use of sex-specific cut-off values. Furthermore, there are no sufficient evidences on the diagnostic accuracy and cost effectiveness related to cut-off values suggested for algorithms to be used by some hs-cTnI methods.

: Thanks to the evolution of laboratory medicine, point-of-care testing (POCT) for troponin levels in the blood (hs-cTn) has been greatly improved in order to quickly diagnose acute myocardial infarction (AMI) with an accuracy similar to standard laboratory tests. The rationale of the HEART POCT study is to propose the application of the 0/1 h European Society of Cardiology (ESC) algorithm in the pre-hospital setting using a POCT device (Atellica VTLi). : This is a prospective study comparing patients who underwent pre-hospital point-of-care troponin testing (Atellica VTLi) with a control group that underwent standard hospital-based troponin testing (Elecsys).

Background: Biomarkers are used for long-term risk prediction of cardiovascular (CV) events in patients presenting with suspected acute coronary syndromes.
Objectives: This study investigated whether there are sex differences in the long-term prognostic value of biomarkers in patients presenting with suspected non-ST-segment elevation acute coronary syndrome (NSTE-ACS).
Methods: High-sensitivity cardiac troponin (hs-cTn), hs-cTnI, N-terminal pro-B-type natriuretic peptide (NT-proBNP), growth differentiation factor (GDF)-15, and C-reactive protein (CRP) concentrations were measured in 1,476 patients admitted with suspected NSTE-ACS.

Spontaneous coronary artery dissection (SCAD) is a rare condition that frequently goes undiagnosed. Still, it is becoming an increasingly recognized cause of acute coronary syndrome (ACS), predominantly in middle-aged women with few or no cardiovascular risk factors. We present a case of a 53-year-old female with traditional cardiovascular risk factors, who presented with typical anginal symptoms and was diagnosed with SCAD in the mid to distal left anterior descending artery (LAD).

Background: Specialist cardiac care has been shown to reduce inpatient mortality following non-ST segment myocardial infarction (NSTEMI), but whether this benefit extends beyond index admission is unclear.
Methods: Using the linked Myocardial Ischaemia National Audit Project (MINAP) registry, and Office for National Statistics mortality recording, we included 425,205 NSTEMI patients admitted to UK hospitals, between January 2005 and March 2019 that survived to discharge. 217,964 (52 %) were admitted to a specialty cardiac ward.

Gunshot-related myocardial injuries typically result from direct penetrating injury by the traversing bullet. We present a case of gunshot-related myocardial injury in the absence of direct penetrating injury to the cardiac structures and describe alternative mechanisms for ballistic-induced injury.
