Growth differentiation factor 15 in cardiovascular diseases: from bench to bedside.

Context: Growth differentiation factor 15 (GDF-15) is a novel cytokine showing close association with cardiovascular diseases. The biological mechanism and clinical use of GDF-15 in cardiovascular diseases have been well demonstrated. We review recent investigations from both basic research and clinical trials into the biological role of GDF-15.

Methods: The data were obtained mainly from MedLine via PubMed and from our own investigations.

Results: Laboratory investigations revealed that GDF-15 has biphasic effects on cellular survival by several signaling pathways. GDF-15 participates in several cardiovascular pathological processes such as cardiac remodeling, ischemia/reperfusion injury and atherosclerotic plaque formation. As well, GDF-15 was found a prognostic biomarker of heart failure and acute coronary syndrome. The evidence for diagnostic or therapeutic utility is poor.

Conclusion: GDF-15 has great potential as a biomarker in cardiovascular diseases, especially for prognosis, and is seen as a myocardial protective cytokine, but the exact mechanism of GDF-15 in cardiovascular diseases remains unknown.
