Abstract
Introduction: Chest pain is one of the leading causes of visits to the emergency department, identifying situations that endanger life, especially acute coronary syndromes (ACS), becomes the priority. The Braunwald and TIMI scales are two of the approximations used in the initial classification of patients.
Methodology: From a database obtained from a study of the application of critical paths in the diagnosis of ACS, consisting of patients with chest pain, we conducted an exploratory study in which, from a latent class analysis is evaluated the components of these scales.
Results: It is founded that the best model is the one that comprises two latent classes for the case of Braunwald and three for the TIMI. Suggests that could reduce the dimensionality of the scale variables Braunwald excluding investment pulmonary edema and isolated T-wave in a shunt. The TIMI scale does not fit enough to make the diagnostic classification of SCA.
Conclusion: Latent class analysis could be used to classify groups for chest pain classification in ACS or reduce the dimensionality.
