Abstract
RONCALLO, Ella C.; RUIZ, Álvaro J.; SOLANO, Erick R. and RODRIGUEZ-MALAGON, Nelcy. Usefulness of the CPU-65 index in adults with chest pain and normal or non-diagnostic electrocardiogram. Rev. Colomb. Cardiol. [online]. 2021, vol.28, n.5, pp.410-420. Epub Nov 29, 2021. ISSN 0120-5633. https://doi.org/10.24875/rccar.m21000078.
Objective:
To evaluate the clinical usefulness, in the emergency service, of the UDT-65 index for chest pain stratification in colombian population with suspected coronary disease.
Method:
The external validation of the UDT-65 index was conducted in a concurrent cohort that included patients admitted to the emergency service of the cardiovascular clinic in Bogotá with non-traumatic chest pain and normal or non-diagnostic electrocardiogram. 1320 patients were evaluated and the usefulness of this instrument was determined in terms of calibration (use of graph, Chi-square test for group data and the Hosmer-Lemeshow goodness-of-fit test) and discrimination capacity of the model (curve of receiver operating characteristics [ROC] and by finding the area under the curve [AUC]).
Results:
The UDT-65 index in the population under study, provided evidence of its usefulness in terms of calibration and discrimination capacity; this, in pursuance of a good application of the instrument in those patients who consult the Emergency Department of the cardiovascular clinic for non-traumatic chest pain of possible coronary origin. The discrimination capacity of the UDT65 index was adequate, with an area under the ROC curve of 0.867 (95 % CI 0.847-0.885), which is close in value to the one obtained (AUC 0.87) in the Spanish population where the original index was developed.
Conclusions:
More similar studies are needed in other institutions, due to the excellent and beneficial outcomes.
