Resumen

GARCIA-PENA, Ángel Alberto et al. Relationship of ST segment/heart rate slope index and ST segment change index scores on the heart rate change during conventional stress test with the presentation of new cardiovascular events. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.1, pp.5-7. ISSN 0120-5633.  http://dx.doi.org/10.1016/j.rccar.2016.09.007.

Introduction:

Conventional stress test is a diagnostic tool easy to interpret and of easy Access frequently used in the assessment of chest pain; however, its operational characteristics are influenced by multiple variables, resulting in a limited ability for global prediction of cardiovascular outcomes. The use of indexes and additional variables in their interpretation could improve prediction of cardiovascular outcomes.

Methods:

By conducting a descriptive, analytical and retrospective study, the relationship and prediction ability of the slope ST/HR and ΔST/ΔHR indexes with the development of cardiovascular

events were assessed at one year. Out of a total of 438 studies, 138 were selected that complied with the evaluation criteria. A descriptive analysis of the variables of interest was carried out, and later on a univariate and multivariate analysis of the different variables and outcomes of interest.

Conclusions:

A statistically significant relationship was found between exercise capacity, ST/HR slope index and the development of cardiovascular events, without findings of a significant relationship with the ΔST/ΔHR slope index. A discreet improvement of the global prediction capacity of the conventional stress test with the addition of the ST/HR slope index (AUC 0.70 to AUC 0.74) is observed.
