Sivelestat sodium treatment after off-pump coronary artery bypass grafting (OPCABG)

Prospective Double-Blind Controlled Study of Sivelestat Sodium in the Perioperative Management of Off-Pump Coronary Artery Bypass Grafting

Phase 2 Interventional Affiliated Hospital of Nantong University · NCT07118930

This trial will test whether giving sivelestat sodium after off-pump coronary bypass surgery helps protect the heart and reduce inflammation in adults having OPCABG.

What this trial studies

This Phase 2, randomized, double-blind, placebo-controlled trial gives either sivelestat sodium or saline starting 2 hours after elective OPCABG and continuing for 72 hours. Researchers will track blood markers of myocardial injury (hs-cTnT, CK-MB, NT-proBNP), echocardiographic measures of cardiac function (GLS, LVEF), inflammatory markers (IL-6, CRP, PCT), and short-term clinical outcomes such as ventilation time, ICU stay, and 30-day adverse events. The trial enrolls adults having elective OPCABG with preserved-ish ventricular function and excludes emergency or combined major cardiac surgeries and significant preoperative liver/kidney dysfunction. All procedures and follow-up are conducted at the Affiliated Hospital of Nantong University under blinded conditions.

Who should consider this trial

Good fit: Adults scheduled for elective off-pump coronary artery bypass grafting with at least two grafts and LVEF ≥35% who meet liver and kidney function limits and can give informed consent are ideal candidates.

Not a fit: Patients needing emergency surgery, combined valve or aortic procedures, those with significant preoperative liver/kidney dysfunction, active infection, autoimmune disease, or recent potent anti-inflammatory/immunosuppressant use are unlikely to be eligible or benefit.

Why it matters

Potential benefit: If successful, sivelestat could reduce heart muscle injury and inflammation after OPCABG, potentially shortening ICU stays and improving short-term recovery.

How similar studies have performed: Sivelestat, a neutrophil elastase inhibitor, has shown anti-inflammatory benefit in some prior acute lung and ischemia–reperfusion contexts, but its use specifically after OPCABG is novel and not yet established.
