Copeptin a marker for diagnosis and prognosis in heart attack

Plain English Summary

Background and study aims
Chest pain can be caused by a variety of conditions, some of them dangerous (such as a heart attack), others harmless (such as a muscle pain). The aim of the study is to show if a new marker (a protein measured in the blood ) Copeptin, may be helpful in quickly identifying patients at higher risk for having a heart attack, thus enabling quick introduction of adequate treatment.

Who can participate?
Adult experiencing chest pain lasting five minutes or more within the last 6 hours.

What does the study involve?
Copeptin is measured for all participants via a blood test on admission to hospital. They then undergo routine treatment according to current guidelines and standards of care. Participants' follow-up data are collected and analyzed in regard to Copeptin concentrations.

What are the possible benefits and risks of participating?
The marker is measured from a blood sample which is taken at the same time as a standard blood test, so does not need additional puncture if the vein. Thus, the risk for participation in the study is minimal.

Where is the study run from?
2nd Department of Cardiology, Medical University of Silesia (Poland)

When is the study starting and how long is it expected to run for?
December 2011 to December 2018

COPACS - COPeptin for Acute Coronary Syndrome

Study hypothesis

Copeptin, the C-terminal part of prohormone for vasopressin, is a marker of acute endogenous stress. An immediate increase in concentration after a few minutes from the onset of chest pain and rapid peak of concentration (1-2h) have practical implications for chest pain patients. Together with cardiac troponin, which is a specific marker for myocardial injury, it could be effective in quickly identifying patients at higher risk for having a heart attack, thus enabling quick introduction of adequate treatment. The aim of this study is to see whether this is the case.

Condition

Chest pain

Intervention

Copeptin is measured in patients with chest pain lasting up to 6h at admission and remains double-blinded throughout the enrollment. Further all patients undergo routine management for the condition being the cause of admission, according to current guidelines and standards of care. Patients' follow-up data are collected and analyzed in regard to copeptin concentrations.

Intervention type

Other

Primary outcome measure

1. Primary diagnostic endpoint is the final diagnosis of NSTEMI
2. Primary prognostic endpoint is death of cardiovascular origin

Secondary outcome measures

1. Secondary diagnostic endpoint is the diagnosis of ACS (NSTEMI+UA)
2. Secondary prognostic endpoints is as Major Adverse Cardiac and Cerebrovascular Events (MACCE) and included death of cardiovascular origin, non-fatal AMI, UA, repeated cardiac revascularization, stroke
