Definite Stent Thrombosis in Comatose Out of Hospital Cardiac Arrest Survivors
An observational study of Out of Hospital Cardiac Arrest and Stent Thrombosis, run by University Medical Centre Ljubljana at 1 site in Slovenia.
Trial summary
Reliable data on stent thrombosis (ST) in comatose out of hospital cardiac arrest (OHCA) survivors is lacking. In comatose OHCA survivors suspicion of ST can be made with precise clinical monitoring of the patient with definite confirmation being possible only by coronary angiography or autopsy of deceased patients.

About this study
Official title: Definite Stent Thrombosis in Comatose Out of Hospital Cardiac Arrest Survivors Treated With Percutaneous Coronary Intervention and Hypothermia
Reliable data on stent thrombosis (ST) in comatose out of hospital cardiac arrest (OHCA) survivors is lacking. In comatose OHCA survivors suspicion of ST can be made with precise clinical monitoring of the patient with definite confirmation being possible only by coronary angiography or autopsy of deceased patients. However in addition to definite ST which can be confirmed using current protocols, additional ST which are clinically silent are plausible. These could be identified only by systematic coronary angiography of all OHCA survivors or by autopsy of deceased patients. Collectively with definite ST confirmed by coronary angiography upon clinical suspicion the incidence of all forms of ST in survivors of OHCA treated with PCI and hypothermia could be obtained.
Consecutive comatose survivors of OHCA treated with percutaneous coronary intervention (PCI) and hypothermia will be included. All study participants will receive treatment per our established clinical protocol and will be followed for 10 days. In all patients in whom clinical suspicion of ST will be made immediate coronary angiography and if necessary PCI will be carried out. In all patients that will die in the observed period of 10 days autopsy will be performed. Survivors however will have an additional control coronary angiography on 10th day after admission, to assess presence of clinically silent ST.
We expect that the incidence of true definitive ST in comatose OHCA survivors treated with urgent PCI with stenting and hypothermia is greater than one, which is confirmed on the basis of clinical suspicion by angiography or later with autopsy.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Reliable data on stent thrombosis (ST) in comatose out of hospital cardiac arrest (OHCA) survivors is lacking. In comatose OHCA survivors suspicion of ST can be made with precise clinical monitoring of the patient with definite confirmation being possible only by coronary angiography or autopsy of deceased patients. However in addition to definite ST which can be confirmed using current protocols, additional ST which are clinically silent are plausible. These could be identified only by systematic coronary angiography of all OHCA survivors or by autopsy of deceased patients. Collectively with definite ST confirmed by coronary angiography upon clinical suspicion the incidence of all forms of ST in survivors of OHCA treated with PCI and hypothermia could be obtained.
Consecutive comatose survivors of OHCA treated with percutaneous coronary intervention (PCI) and hypothermia will be included. All study participants will receive treatment per our established clinical protocol and will be followed for 10 days. In all patients in whom clinical suspicion of ST will be made immediate coronary angiography and if necessary PCI will be carried out. In all patients that will die in the observed period of 10 days autopsy will be performed. Survivors however will have an additional control coronary angiography on 10th day after admission, to assess presence of clinically silent ST.
We expect that the incidence of true definitive ST in comatose OHCA survivors treated with urgent PCI with stenting and hypothermia is greater than one, which is confirmed on the basis of clinical suspicion by angiography or later with autopsy.

Questions about this trial
What is this clinical trial studying?
An observational study of Out of Hospital Cardiac Arrest and Stent Thrombosis, 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 3 inclusion and 1 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 30 Sep 2021. 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?
Incidence of definite early ST until day 10 (time frame: 10 days). 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 NCT03312296, which also lists 7 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 30 Sep 2021; AzTrials last refreshed its copy on 8 Nov 2026.
