Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective observational cohort study of ED patients with acute chest pain or other symptoms suggestive of ACS. Blood samples will be collected from study participants for High-Sensitivity Cardiac Troponin T (hs-cTnT) analysis. Results from hs-cTnT will be used for research purposes only.

Providers will be blinded to results and participants will be treated by their healthcare providers per the standard of care. Participants will have 30 and 90 day phone follow-ups to ascertain study outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately 8 million - 10 million patients complaining of chest pain present to an Emergency Department (ED) annually in the United States. To avoid missing the diagnosis of acute coronary syndrome (ACS), physicians use a liberal testing strategy. Thus, \>50% of ED patients with acute chest pain are hospitalized for a comprehensive cardiac evaluation (serial cardiac biomarkers and stress testing or angiography). However, \<10% of these patients are ultimately diagnosed with ACS, and this pervasive over-triage costs an estimated $10 billion - $13 billion annually. Current care patterns for acute chest pain fail to focus health system resources, such as hospitalization and stress testing, on patients most likely to benefit.

It has demonstrated that an accelerated diagnostic protocol (ADP), called the HEART Pathway, which utilizes a clinical decision aid (the HEART score) and serial Cardiac Troponin (cTn) measures are sensitive for ACS (\>99%) and can substantially reduce hospitalizations, stress testing, and cost compared to usual care. The HEART Pathway uses contemporary serial cTn measurements at 0 and 3 hours to exclude index myocardial infarction (MI) and relies on clinical features (history, ECG, age, and risk factors) to identify patients likely to have downstream events. However, the HEART Pathway has limitations: a) It identifies only 20 - 40% of patients for early discharge and b) it was developed before high-sensitivity cTn assays became available. Able to detect MI earlier and with greater accuracy than contemporary assays, hs-cTn assays have the potential to be integrated into decision aids to improve chest pain risk stratification. In the near future, hs-cTn assays will replace contemporary assays in the United States.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ED Patients with Acute Chest Pain

Emergency Department (ED) Patients with Acute Chest Pain will have blood samples collected for High sensitivity cardiac troponin T (hs-CTnT) analysis. Results from this analysis will be integrated into the HEART Score/Pathway. It will later be seen if integration of the hs-cTnT outperforms the use of HEART Score/Pathway alone.

Blood Sample

Intervention Type PROCEDURE

Blood samples will be collected from study participants for hs-cTnT analysis. Results of hs-cTnT will be used for research purposes only. Providers and participants will be blinded to results and participants will be treated by their healthcare providers per the standard of care.

HEART Score

Intervention Type BEHAVIORAL

The HEART Score is a prospectively studied scoring system to help emergency departments risk-stratify chest pain patients. Patients score on a scale of 0-10.
