Growth-differentiation factor-15 and major cardiac events

Area of Science:

• Cardiology
• Biomarkers
• Clinical Research

Background:

• Growth-differentiation factor (GDF)-15 is a known predictor of cardiovascular events in ST-elevation myocardial infarction (STEMI).
• The impact of GDF-15 on left ventricular (LV) remodeling post-STEMI requires further clarification.

Purpose of the Study:

• To investigate the predictive value of GDF-15 for LV remodeling, heart failure, and mortality in STEMI patients.
• To assess the relationship between GDF-15 levels and echocardiographic changes in STEMI survivors.

Main Methods:

• 216 STEMI patients had GDF-15 levels measured on day 2 of hospitalization.
• Echocardiography was performed at baseline and 6 months post-STEMI.
• Clinical outcomes, including death and heart failure readmission, were tracked for up to 3 years.

Main Results:

• Higher GDF-15 levels were associated with lower LV ejection fraction at baseline and 6 months.
• GDF-15 level was not a predictor of increased LV end-diastolic volume index.
• Combined high GDF-15 and N-terminal pro-B-type natriuretic peptide predicted death and heart failure (P < 0.001).
• Independent predictors of death and heart failure included age, GDF-15 level, and diabetes mellitus.

Conclusions:

• Elevated GDF-15 levels strongly predict mortality and heart failure in STEMI patients.
• Despite lower ejection fraction, higher GDF-15 levels did not correlate with increased LV remodeling.
• GDF-15 serves as a valuable prognostic biomarker in the STEMI population.
