Utilizzo in Pronto Soccorso dei metodi ad alta sensibilità per le troponine cardiache per i pazienti con sospetto di infarto acuto del miocardio senza sopraslivellamente del tratto ST Documento Congiunto del Gruppo di Studio Inter-Societario sui Biomarcatori Cardiaci delle Società Italiane di Biochimica Clinica: European Ligand Assay Society, Sezione Italiana (ELAS), Società Italiana di Biochimica Clinica e Biologia Molecolare Clinica (SIBioC), Società Italiana di Patalogia Clinica e Medicina di Laboratorio
Use of the high-sensitivity methods for cardiac troponins measurement in patients admitted to the Emergency Department with a clinical suspicion of a non-ST segment elevation myocardial infarction Joint document of the Italian Societies of Clinical Biochemistry: European Ligand Assay Society, Sezione Italiana (ELAS), Società Italiana di Biochimica Clinica e Biologia Molecolare Clinica (SIBioC), Società Italiana di Patologia Clinica e Medicina di Laboratorio (SIPMeL).
<p>The use of serial measurement of cardiac troponin (cTn) is recommended by international guidelines for the diagnosis of myocardial infarction (MI) since 2000. However, the are some relevant differences among the recommendations proposed by the three different international guidelines published in 2020-2021 for the management of patients admitted to the Emergency Department (ED) with a clinical suspicion of a non-ST-segment elevation MI (NSTEMI). In particular, there is no agreement among these authoritative international guidelines about the cut-off or absolute change values to be used for diagnosis of MI. Another important controversial issue is whether there are, at present time, sufficient evidences on the diagnostic accuracy and cost effectiveness related to cut-off values suggested for the most rapid algorithms (0-1 or 0-2 hours) recommended for the rule-in/rule-out of NSTEMI. Finally, another important issue concerns the possible bias existing between the demographic and clinical characteritics of the patients enrolled in some multicenter trials compared to those routinely admitted to ED of the city Hospitals of some European countries, including Italy, for the diagnosis of NSTEMI. Considering the recommendations from these international guidelines, the Study Group of Cardiac Biomarkers, supported by the Italian Scientific Societies SIBioC&nbsp;(Societ&agrave; Italiana di Biochimica Clinica), ELAS (Italian Society of the European Ligand Assay Society) and SIPMeL (Societ&agrave; Italiana di Patologia Clinica e medicina di Laboraratorio), decided to revise the document previously published in 2013 about the management of patients admitted to ED with suspect NSTEMI, and so to prepare suggestions more specifically designed for the clinical institutions operating in the healthcare system in Italy.</p>

Calcolo e valutazione dei valori di riferimento della troponina cardiaca I (cTnI) misurata in un gruppo di volontari sani italiani con metodi immunometrici ad alta sensibilità: uno studio multicentrico
Establishment and evaluation of cardiac troponin I reference values measured in a group of Italian healthy volunteers using high-sensitivity methods: a multi-center study.
<p>Introduction: this study compares the cardiac troponin I (cTnI) values measured with three high-sensitivity (hs) different methods in apparently healthy volunteers enrolled in a multicenter study.<br />Methods: heparinized plasma samples were collected from 1511 volunteers in 8 Italian clinical institutions (mean age 51.5 years, SD 14.2, range 18-86, female to male ratio 0.94). All volunteers denied chronic or acute diseases and had normal values of routine laboratory tests and ECG. The reference laboratory of the study (Laboratorio Fondazione CNR Regione Toscana G. Monasterio, Pisa, Italy) assayed all plasma samples with three hs-methods: Architect hs-cTnI, Access hs-cTnIand ADVIA Centaur XPT hs-cTnI. After the exclusion of outlier values, calculation of 99th percentile (Upper Reference Limit, URL) values was performed using both robust nonparametric and bias corrected and accelerated bootstrap methods.<br />Results: large between-method differences were found. ADVIA Centaur measured higher cTnI values (up to 2-fold) than the two other methods. cTnI values were significantly higher in men than in women, and progressively increased with age over 55 years. Moreover, 99th percentile URL values also depended on the statistical approach used for calculation (robust non-parametric versusbootstrap). All 99th percentile URL values calculated with non-parametric robust method were on average slightly lower than those suggested by manufacturers (mean difference 4.2 ng/L, standard error 1.7, p=0.0273).<br />Conclusion: clinicians should be advised that plasma samples from the same patient should be measured for hs-cTnI in the same laboratory. Specific clinical studies are needed to establish the most appropriate statistical approach to calculate 99th percentile URL values for hs-cTnI methods.</p>
