Accelerated Diagnostic Protocols Based on High-Sensitivity Troponin in the Diagnosis of Thoracic Pain: A Systematic Review

pp. 279-286

Abstract

Background: The progress of high-sensitivity troponin for accelerated diagnostic protocols to assess chest pain, allows the identification of patients admitted to the emergency room with low-risk chest pain for a major adverse cardiovascular event, that could be early and safely discharged, saving time and resources.

Objective: The aim of this study was to assess clinical trials using accelerated diagnostic protocols based on high-sensitivity troponin.

Methods: A search of randomized clinical trials evaluating accelerated diagnostic protocols based on high-sensitivity troponin in emergency services was carried out in MEDLINE/Ovid, Cochrane and EMBASE database, using the assessment criteria of the Cochrane manual and the PRISMA strategy.

Results: After screening 3509 studies, 5 clinical trials, including 1513 patients, were analyzed. Early discharges were identified in 409 (27%) of patients, in 91% of cases for ESC 0/3-h protocols, 72% for 0/1-h, 48% for EDACS, 40% for HEART, 19% and 32% for ADPT and 8% and 18% for standard care protocols. The negative predictive value was high, in the 99.1-100% range. Mean length of hospital stay was lower for the 0/1-h and ESC 0/3-h protocols, with 4.6 and 5.6 hours, respectively.

Conclusions: Accelerated diagnostic protocols in chest pain using high-sensitivity troponin allow a higher proportion of early discharges with a low rate of major cardiovascular events, with reduction in length of hospital stay and resources used.
