Abstract
Objectives About 10 million individuals in USA presented annually in the emergency department (ED) with chest pain or with signs and symptoms of acute coronary syndrome (ACS). The advent of point of care (POC) devices, able to measure high sensitivity troponin, are a very interesting tool in the ED setting for its rapid turnaround time ( Methods The present study evaluates the diagnostic performance of the Atellica VTLi (Siemens) in real life setting using the clinical data derived from integrated diagnoses of emergency room staff and cardiologist and in comparison with standard laboratory hs-cTnT assay (Cobas 8000, Elecsys, Roche). 966 patients admitted to the emergency department of “G. Mazzini Hospital” in Teramo, Italy, from July 27, 2022, through June 09, 2023, were enrolled. Results The diagnostic performance of POC hs-cTnI was evaluated. An appropriate POC hs-cTnI threshold values 54 ng/L provided a specificity of 97.2 % (95 % CI: 95.9–98.1) and a PPV of 43.5 % (95 % CI: 40.3–46.7) for ruling in MI. Conclusions This platform showed comparable diagnostic performance for myocardial infarction to the central laboratory. Our data suggest the possible use of the Atellica VTLi hs-cTnI POC assay either in emergency department of urban medical centre, either in rural hospital for triage and patient management.
