N2 - High sensitive cardiac Troponin T (hs-cTnT) represents an important tool in acute myocardial infarction (AMI) diagnosis. Even though the hs-cTnT evaluation is relevant for AMI diagnosis in elderly patients characterized by clinical and instrumental atypical presentation, the overall reliability in elderly patients is unknown. We aimed at: (1) defining the hs-cTnT 99th percentile value in an aged healthy reference population and (2) testing hs-cTnT diagnostic accuracy in elderly patients with a suspected AMI.294 healthy subjects (50-105 years old) and 299 elderly patients (75-96 years old) with suspected AMI at presentation, were enrolled. Conventional cTnT, hs-cTnT, NT-proBNP and creatinine levels were determined in all participants.Our main results are: (1) a significant hs-cTnT age-related increase was observed in an healthy reference population ranging 50-105 years old; (2) hs-cTnT levels showed an age-related multimodal distribution in the healthy reference population: 16. ng/L corresponds to the 99th percentile in subjects ranging 50-75 years old, whereas 70.6. ng/L corresponds to the 99th percentile in subjects ≥75 years old; (3) 86.8. ng/L resulted the hs-cTnT cut-off value with the highest efficiency in AMI diagnosis of geriatric patients.Our data suggest that the hs-cTnT cut-off value must be age-tailored to improve the AMI diagnostic accuracy.
