Galectin-3, advanced glycated end-products serum levels, endothelial function and cardiac hemo­dynamics in post infarction heart failure patients with reduced and preserved ejection fraction

Epidemiological studies have reported that the rate of signs and symptoms of heart failure after myocardial infarction is approximately 25%. In addition, approximately 40% of myocardial infarctions are accompanied by left ventricular systolic dysfunction. Aim.. Aim of the study is to evaluate serum levels of galactin-3, AGEs and endothelial function, cardiac hemodynamics in post infarction chronic heart failure patients with different ejection fraction. Materials and methods. All patients are divided into two main groups according to ejection fraction:1^st group-20 patients with chronic heart failure with preserved ejection fraction, 2^nd group-15 patients with chronic heart failure and reduced ejection fraction. Standard laboratory blood tests for erythrocyte sedimentation rate, haematological parameters, lipid profile, glucose, renal function, echocardiographic examination, endothelial function determine were performed for all patients. AGEs and galectin-3 serum levels were determined. Results. Patients with chronic heart failure and reduced ejection fraction and myocardial infarction in anamnesis had significantly increased left ventricle diastolic volume, left ventricle systolic volume,left ventricle diastolic dimension and left ventricle systolic dimension (p<0.05).AGEs serum level mildly increased in both groups.Galectin-3 level was significantly higher in pts with chronic heart failure and reduced ejection fraction(p < 0.05)and was correlated with age(R=0.74, p<0.05), left ventricle end diastolic volume (R=0.57, p<0.05), left ventricle end diastolic dimension (R=0.48, p<0.05), triglycerides level (R=0.45, p < 0.05). Most of the patients with chronic heart failure with myocardial infarction in anamnesis had endothelial dysfunction, the FMD% level was significantly higher in patients with preserved ejection fraction(p<0.05). Conclusions. Patients with chronic heart failure and reduced ejection fraction are characterized by significantly higher levels of galectin-3, endothelial dysfunction frequency, cardiac hemodynamics abnormalities.
