About this study

Cardiovascular diseases are the first mortality cause in Occidental countries. Surgery and anesthesia can provoke hemodynamic instability and stimulation of the sympathetic nervous system as well as bleeding or thrombosis. These factors as top of some post-operative factors such as tissular hypoxemia, can result in cardiovascular complications. Developing a tool to predict post-operative cardiovascular complication could influence peri-operative measures by stratifying the population at risk. UCLouvain has developed a patented technique using a paramagnetic electronic resonance spectrometry (EPR) able to quantify a paramagnetic component, nitrosylated hemoglobin (HbNO) of the erythrocytes drawn from venous blood. This HbNO has been correlated to the traditional cardiac risk factors. In this study, we will assess the HbNO of patients prior to surgery and will correlate it with cardiovascualr and non cardiovascular complications in order to evaluate the predictive aspect of our biomarker.

Read the detailed description

Cardiovascular diseases are the first mortality cause in Occidental countries. They would be the cause of 31% of the overall mortality in those countries.

Some risk factors are strongly related to the apparition of a cardiovascular disease, including smoking, high cholesterol levels, hypertension, diabetes, age, high BMI or familial early cardiovascular disease and/or hypercholesterolemia.

Multiple studies have already shown that major non-cardiac surgery can lead to cardiovascular complications in 3% of the patients regardless of their cardiovascular risk profile and major adverse cardiovascular events are a significant source of post-operative morbidity in approximately 11% among those patient3,4,6,7. Complications can also lead to a prolongated hospitalization for patients undergoing major non-cardiac surgery8,9.The peri- and post-operative cardiovascular complications depend on patient-related risk factors.

Surgery and anesthesia can provoke hemodynamic instability and stimulation of the sympathetic nervous system. Surgery and the ensuing inflammation can also induce bleeding and or thrombosis. These factors as top of some post-operative factors such as tissular hypoxemia, can result in cardiovascular complications.

An assessment of the medical cardiac history of the patients is performed before any surgery3. Developing a tool to predict post-operative cardiovascular complication could influence peri-operative measures by stratifying the population at risk.

It is known that cardiovascular diseases are preceded by a dysfunction of the vascular endothelium leading to a loss of the antithrombogenic, anti-proliferative and vasorelaxant functions.

A key mediator of vascular homeostasis and endothelial integrity is the nitric oxide (NO) produced by the endothelial NO synthetase (eNOS). UCLouvain has developed a patented technique using a paramagnetic electronic resonance spectrometry (EPR) able to quantify a paramagnetic component, nitrosylated hemoglobin (HbNO) of the erythrocytes drawn from venous blood. This HbNO has been correlated to the traditional cardiac risk factors.

Quantifying the HbNO could predict, prior to any major non-cardiac surgery, an eventual peri-operative cardiovascular complication. Preoperative HbNO would as such be a useful marker of cardiovascular complications. Necessary perioperative measures can therefore be taken in order to decrease this risk. This assessment would be associated to the preoperative anesthesia visit (EPI : évaluation péri-interventionnelle) form reporting previous cardiovascular events and risk factors.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Blood sampling for HbNO assessment in people with Cardiovascular Complications, run by Université Catholique de Louvain at 1 site in Belgium.

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 15 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: status not confirmed, as of the sponsor's last update on 21 Nov 2022. 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 Belgium. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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 intra and postoperative cardiovascular complication or degradation within 12 months (time frame: 12 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 21 Nov 2022.
