Determination of Serum Glycogen Synthase 3 Beta Levels in Patients with Heart Failure, a Novel Marker for Diagnosis and Defining Disease Severity?

Glycogen synthase kinase 3β (GSK3β) is an enzyme that has roles in the pathogenesis of heart failure (HF). We try to reveal serum GSK3β levels in types of HF. In this study, we evaluated serum GSK3β levels in HF patients. Also, we tried to elucidate any possible relationship between serum GSK3β levels and disease severity among three different types of HF patients. We performed a prospective study and enrolled 112 patients: 50 patients in heart failure with preserved ejection fraction (HFpEF) group, 30 patients in heart failure with mildly reduced ejection fraction (HFmrEF) group, and 32 patients in heart failure with reduced ejection fraction group (HFrEF). We also evaluated 50 healthy controls. Echocardiographic examinations were performed. We measured serum GSK-3β and N-terminal pro-B-type natriuretic peptide (NT-proBNP). We measured highly sensitive C-reactive protein (hs-CRP) levels and calculated neutrophil-lymphocyte ratio (NLR) platelets-to-lymphocyte ratio (PLR) from the hemogram count. Statistical significance was accepted p < 0.05. Serum GSK3β levels were significantly higher among patients with HF compared to healthy controls (median GSK3β levels; 117.26 (45.39 -223.85) vs 13.91 (5.6 -23.3) ng/mL, p
