About this study
Official title: Combined Use of Dexmedetomidine and Hydrocortisone to Prevent New Onset Atrial Fibrillation After Coronary Artery Bypass Grafting Surgery
Atrial fibrillation (AF) occurs in 20% to 40% of patients after Coronary artery bypass grafting (CABG) and is associated with numerous detrimental sequelae. In postoperative period, the patient may be exposed to several proarrhythmogenic factors as increased endogenous catecholamines, inflammatory and oxidative mediators secondary to surgical stress and the systemic response to cardiopulmonary bypass, use of inotropic support. Steroids suppress the release of the above-mentioned inflammatory mediators. Dexmedetomidine is sympatholytic, along with anti-inflammatory properties. so combined use of both drugs may have synergistic effect to prevent post operative AF (POAF)
Read the detailed description
Postoperative atrial fibrillation (POAF) is a common postoperative complication that occurs in 20% to 40% of patients after Coronary artery bypass grafting (CABAG) and is associated with numerous detrimental sequelae.
POAF is an independent predictor of numerous adverse outcomes, including a 2- to 4-fold increased risk of stroke, reoperation for bleeding, infection, renal or respiratory failure, cardiac arrest, cerebral complications, need for permanent pacemaker placement, and a 2-fold increase in all-cause 30-day and 6-month mortality.
Clinical efforts to prevent and manage POAF following cardiac surgery have thus far presented a major challenge and results have been less than optimal. Despite numerous trials examining prophylactic and treatment modalities, POAF incidence following cardiac surgery has not changed over the past several decades.
The pathogenesis of POAF is incompletely understood but likely involves interplay between pre-existing physiological components and local and systemic inflammation. cardiopulmonary bypass and ischemia/reperfusion injury triggers generalized response characterized by leukocyte and complement activation, high levels of C-reactive protein (CRP) complexes, as well high levels of inflammatory mediators. These mediators, such as interleukins-6 and -8, tumor necrosis factors, leukotriene B4, and tissue plasminogen activator, might contribute to many postoperative complications including atrial fibrillation (AF).
Because of the known physiologic effects of steroids to suppress the release of the above-mentioned inflammatory mediators, steroids might have beneficial effects in decreasing postoperative AF, and inhibiting the inflammatory process post cardiopulmonary bypass. Moreover, they decrease capillary wall permeability, preventing migration of inflammatory mediators into the systemic circulation. Also, Corticosteroids decrease the heterogeneity of atrial conduction and reduce inflammation following cardiac surgery, and studies have shown that preoperative prophylactic corticosteroids reduced POAF incidence without an increased rate of postoperative infection.
Dexmedetomidine is a very specific intravenously and short-acting alpha-2 agonist which theoretically reduces the sympathetic output by decreasing serum levels of norepinephrine and inhibits the release of cytokines and results in reduction of the incidence of tachycardia, inflammation, high blood pressure during and after surgery. Dexmedetomidine reduces heart rate and consequently improves myocardial oxygen demand. It also depresses sinus node and atrial ventricular nodal function which, along with the drug's anti-inflammatory properties, makes dexmedetomidine a reasonable prophylactic drug for postoperative atrial fibrillation.
So, the investigators that combined use of both drugs will have synergistic effect to prevent (POAF) after (CABG) surgery.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Dexmedetomidine + Hydrocortisone in people with Atrial Fibrillation New Onset, run by Ain Shams University at 1 site in Egypt.
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 1 inclusion and 12 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 10 Jan 2023. 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 Egypt. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Occurrence of AF (time frame: Up to 7 days Postoperative). 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 NCT05674253, which also lists 13 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 10 Jan 2023.
