Predicting major heart problems after coronary artery bypass grafting in people with heart failure

Risk Stratification of MACE Based on GDF-15 in Heart Failure Patients Who Undergoing Coronary Artery Bypass Grafting: an Observational Multicenter Prospective Study

Observational Tomsk National Research Medical Center of the Russian Academy of Sciences · NCT07480915

This study will test whether a blood marker called GDF-15 taken before bypass surgery can help predict major heart events over the year after CABG in patients with chronic heart failure and coronary artery disease.

What this trial studies

PROFILE-HF is a prospective, multicenter observational cohort of patients with chronic heart failure and coronary artery disease who are scheduled for coronary artery bypass grafting. At enrollment a preoperative blood sample will be taken and serum stored for measurement of GDF-15, with standardized processing and cold-chain transport to a central laboratory. Participants will be followed for 12 months for major adverse cardiovascular events (MACE) with one planned in-person visit at the end of follow-up or telephone contact if needed. Clinical care and treatments are managed according to standard practice and recorded but not altered by the study.

Who should consider this trial

Good fit: Adults with a documented diagnosis of chronic heart failure and coronary artery disease who are planned for isolated coronary artery bypass grafting and can provide informed consent and a preoperative blood sample are ideal candidates.

Not a fit: Patients with recent myocardial infarction or stroke, implanted cardiac devices, need for additional cardiac surgery, severe renal failure (GFR <30), active cancer, infiltrative or autoimmune cardiac disease, or acute infections were excluded and therefore are unlikely to benefit from the study findings.

Why it matters

Potential benefit: If successful, the test could help identify patients at higher risk of major cardiac events after CABG so clinicians can target closer monitoring or tailored therapy.

How similar studies have performed: Biomarker approaches including GDF-15 have previously shown prognostic value in heart failure and coronary disease cohorts, but using preoperative GDF-15 specifically for CABG risk stratification has been less widely tested.
