NCT05206032

Brief Summary

This study intends to collect about 500 cases of blood samples from acute aortic dissection (AAD) and other acute chest pain diseases (eg, AMI, PE, or angina).The investigators tend to detect Raman metabolic profile of blood samples collected from AAD and other control groups using the Raman spectroscopy. The data collected will be analyzed and used to create a Raman database able to provide a classification model based on machine learning. The investigators then compared them with healthy participants to evaluate the diagnostic performance of different levels of Raman metabolic profile at discriminating AAD from other diagnoses and assess whether Raman metabolic profile is a potential novel biomarker for AAD under different circumstances.

Outcome Measures

Primary Outcomes (3)

  • Identification and characterization of a new AAD blood signature through Raman spectroscopy

    The Raman analysis of blood samples collected from AAD patients and other control groups, will be used to characterize a AAD signature able to discriminate subjects from other chest pain individuals.

    One day

  • Correlation with the clinical characteristics

    Raman data related to subjects with AAD will be correlated with the clinical data, validating in this way our methodology. The principal correlation will be carried out between the D-Dimer and B type urine natriuretic peptide(BNP) concentrations and Raman signature.

    One Day

  • Portable Raman as point of care

    The characterized and implemented classification model will be translated to a portable Raman equipped with a laser emitting at 532 nm and with a spectral resolution comparable with the one of the bench Raman. This station will be firstly tested with patients coming to the hospital and then applied continuously implementing the classification model with new Raman spectra and clinical data. In this way the investigators will highly implement the accuracy, sensitivity, precision and specificity of the model.
