Minocycline Plus Amiodarone Versus Amiodarone Alone for the Prevention of Atrial Fibrillation After Cardiac Surgery

• Status: Not yet recruiting

• Target enrollment: 0
• Participant gender: All

Summary

. New- onset postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery and its occurrence increases with age. POAF can result in clinically significant morbidity and mortality. The national trend in the US is that the population older than 65 years is increasing, making healthcare expenditure related to POAF to be a major burden on health care system. Effective treatment of POAF is imperative in ensuring quality of care and reduction of costs.

In 2021 there is a projected total of 377,763 cardiovascular surgeries in the US alone with approximately half of which will have POAF with longer postoperative length of stay (+3.9 days) and higher discharge costs (+$13,993) than no-POAF patients (Reference: Ann Thorac Surg. 2015 Jan;99(1):109-14). Amiodarone, the currently used therapy, is often insufficient to prevent POAF and has multiple side-effects. In this study, we expect to improve the incidence of POAF by using a common acne drug (Minocycline) that is safe and that could be incorporated in clinical care of this disease.

Criteria

Inclusion criteria are adults, including women and minorities > 18 years of age, who are also willing to participate for the duration of the trial (6 weeks). All non-congenital cardiac operations are included: CABG, valve repair/replacement, or combination of CABG and heart valve operations. Patients should be able to access iPhones and download ECGs using their electronic Devices. Exclusion criteria Patients with prior (within 6 months) or current atrial fibrillation (AF) or flutter, patients undergoing concomitant surgical AF ablation or a history of AF, transcatheter aortic valve replacement or other minimally invasive procedures, prior cerebrovascular event, cardiogenic shock or resuscitation, evidence of hepatic or renal dysfunctions (i.e., an alanine aminotransferase level that is ≥ twice the upper limit of the normal range, or either a serum creatinine level that is ≥ 2.0 mg/dL or need for preoperative dialysis) are excluded. Other exclusion criteria are the following: thyrotoxicosis, pregnancy, severe chronic obstructive pulmonary disease (COPD, with FEV1/FVC <70%), recent history of drug or alcohol abuse, and intolerance to tetracycline or amiodarone. Because a core scientific basis of this trial concerning the role of underlying atrial tissue inflammatory/apoptotic activity, patients with inflammatory conditions such as lupus, severe arthritis, thyroiditis or inflammatory bowel disease are excluded; as are patients taking preoperative immunosuppressant agents, long-term (>10 days) oral corticosteroids (prednisolone > 10mg or other), or estrogen replacement; and finally patients with newly diagnosed cancer (<5 years) are also excluded.
