Sensitive Troponin I in Out-of-hospital Cardiac Arrest
An observational study of Cardiac Arrest and Acute Coronary Lesion, run by University Medical Centre Ljubljana at 1 site in Slovenia.
Trial summary
Troponin is a major diagnostic criterion of acute myocardial infarction (AMI) which confirms myocardial damage and necrosis. In out-of-hospital cardiac arrest (OHCA) patients its dynamics and diagnostic value is often controversial and has not been well described. Read more about this study

About this study
Official title: Sensitive Troponin I and Coronary Anatomy in Patients With Out-of-hospital Cardiac Arrest
Troponin is a major diagnostic criterion of acute myocardial infarction (AMI) which confirms myocardial damage and necrosis. In out-of-hospital cardiac arrest (OHCA) patients its dynamics and diagnostic value is often controversial and has not been well described. Most of prior studies were retrospective, using first generation troponin assays and assessing only admission troponin. The aim of this work is to correlate dynamics of sensitive troponin I with urgent coronary angiography.
Patients resuscitated after OHCA will be prospectively divided in three groups based on the results of their urgent angiographies. Serial assessment of sensitive troponin I will be obtained over initial 48 hours.
We expect admission troponin will not be predictive of AMI. Over next hours troponin levels will be highest in patients with acute coronary lesion, lower in stable obstructive coronary disease and insignificant in non-obstructive coronary disease. We also expect significant difference in highest values and dynamics of troponin in sub-group with spontaneous reperfusion (TIMI flow 2 and 3) comparing to patients with coronary occlusion (TIMI flow 0 and 1). In patients with non-obstructive disease we expect troponin levels to correlate with duration of cardiac arrest, number of external electric shocks and cumulative dose of adrenaline administered.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Troponin is a major diagnostic criterion of acute myocardial infarction (AMI) which confirms myocardial damage and necrosis. In out-of-hospital cardiac arrest (OHCA) patients its dynamics and diagnostic value is often controversial and has not been well described. Most of prior studies were retrospective, using first generation troponin assays and assessing only admission troponin. The aim of this work is to correlate dynamics of sensitive troponin I with urgent coronary angiography.
Patients resuscitated after OHCA will be prospectively divided in three groups based on the results of their urgent angiographies. Serial assessment of sensitive troponin I will be obtained over initial 48 hours.
We expect admission troponin will not be predictive of AMI. Over next hours troponin levels will be highest in patients with acute coronary lesion, lower in stable obstructive coronary disease and insignificant in non-obstructive coronary disease. We also expect significant difference in highest values and dynamics of troponin in sub-group with spontaneous reperfusion (TIMI flow 2 and 3) comparing to patients with coronary occlusion (TIMI flow 0 and 1). In patients with non-obstructive disease we expect troponin levels to correlate with duration of cardiac arrest, number of external electric shocks and cumulative dose of adrenaline administered.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiac Arrest and Acute Coronary Lesion, run by University Medical Centre Ljubljana at 1 site in Slovenia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Peak Troponin I value (time frame: Within 48 hours after hospital admission). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02713048, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2018.
