Clinical Trial Summary

This is an interventional, double-blind, placebo controlled, multicenter, randomized clinical trial with allocation sequence concealment and blinded endpoint adjudication. The goal of present study is to investigate if periprocedural administration of 10 mg once daily empagliflozin, a sodium-glucose cotransporter-2 inhibitor (SGLT2I), can reduce the incidence of post-operative atrial fibrillation and/or atrial flutter in patients with chronic coronary syndrome scheduled for isolated CABG. This trial will be conducted in two referral teaching cardiology hospitals in Tehran. 492 adult patients who are scheduled for elective isolated coronary artery bypass graft (CABG) surgery will be randomly assigned to one of the groups of intervention (empagliflozin 10 mg daily) or placebo starting 3 days before surgery until discharge.

Description:

Study aim: Evaluating the role of empagliflozin on the rate of postoperative atrial fibrillation in comparison with placebo Design: Two arms, parallel-group, phase 3, randomized, double-blind, placebo-controlled trial on 492 patients Settings and conduct: Recruitment site: Tehran Heart Center and Rajaie Cardiovascular Medical and Research Center For blinding, the drug or placebo will be given to the ward based on the patient's code in the randomization system For monitoring, the blood samples for creatinine, sodium, potassium, and fasting blood sugar along with clinical evaluations will be given on day 0 and daily thereafter (max= 30 days) in specific wards and will be compared at the end of any atrial fibrillation lasting longer than 30 seconds based on 24-hour 12-lead ECG monitoring will be accepted as atrial fibrillation After entering the study, the patients are placed in one of two groups, sample and control; in the sample group, they are treated with the usual treatment regimen plus empagliflozin at a dose of 10 mg during the hospitalization period. Patients in the control arm will receive a matching placebo.

Primary	Incidence of POAF	Incidence of new-onset postoperative atrial fibrillation (AF) and/or atrial flutter (AFL), defined as any adjudicated documented AF or AFL of at least 30 seconds duration and documented by Holter ECG monitoring during the admission time in the ICU (at least 72 hours and maximum 30 days).	From CABG until discharge from the intensive care unit (at least 72 hours and maximum 30 days)
Secondary	Composite Incidence of all arrhythmias leading to hemodynamic instability	Defined as any adjudicated documented tachy- or bradyarrhythmia of at least 30 seconds duration and documented by rhythm strips or 12-lead ECG leading to hemodynamic instability during the admission time. Ventricular tachycardia (VT) of at least 30 seconds duration and documented by rhythm strip or 12-lead ECG.; Ventricular fibrillation (VF) of at least 30 seconds duration and documented by rhythm strip or 12-lead ECG	From CABG until discharge from the hospital (maximum 30 days).
Secondary	Incidence of post-operative acute kidney injury	Defined as the presence of either the increase in serum creatinine by = 0.3 mg/dl (= 26.5 µmol/l) within 48 hours; or an increase in serum creatinine to = 1.5 times baseline, which is known or presumed to have occurred within the prior 7 days; or urine volume < 0.5 ml/kg/h for 6 hours based on the KDIGO definition of AKI	From CABG until 7th post-operation day.
Secondary	Need for vasopressor/inotrope	Defined as cumulative vasopressor index and the amount of average daily inotrope dose during the admission time in the ICU	From CABG until discharge from the intensive care unit (maximum 30 days).
Secondary	Duration of hospitalization	Defined as number of days a patient stay at the hospital	From CABG until discharge from the hospital.
Secondary	All-cause mortality	Defined as adjudicated 30-day mortality, including cause-specific mortality: cardiac arrhythmic, cardiac non-arrhythmic, and non-cardiovascular.	From CABG until 30th post-operation day.
Secondary	Incidence of life-threatening infections	Defined as any adjudicated laboratory and clinically confirmed systemic infection that necessitate the administration of parenteral broad spectrum antibiotics	From CABG until discharge (maximum 30 days).
Secondary	Incidence of genitourinary tract infections	Defined as any adjudicated laboratory and clinically confirmed genitourinary tract infection including cystitis, pyelonephritis, prostatitis, urethritis, and vaginitis	From CABG until discharge from the hospital (maximum 30 days).
