The evaluation of the prognostic effect of NT-pro BNP levels and left entricular ejection fraction in acute decompansated heart failure during levosimendan treatment
Amaç: Akut dekompanze kalp yetmezliği nedeniyle levosimendan tedavisi alan hastalarda serum NT-pro BNPdüzeyleri ve sol ventrikül ejeksiyon fraksiyonunun prognostik öneminin araştırılması.Yöntem: NYHA sınıflamasına göre sınıf IV fonksiyonel kapasiteye sahip, intavenöz ve vazodilatör tedaviyecevap vermeyen ve düşük kardiyak debi bulgularına sahip 14 kalp yetmezliği hastası ( 10 erkek (%71.4), 4 kadın(%28.6) çalışmaya dahil edildi. Klinik durum, hemodinamik parametreler olarak sistolik (SBP) ve diastolik kanbasıncı (DBP) değerleri, serum NT-pro BNP, BUN, kreatinin, Na+, K+, AST, ALT, Hb, Htc düzeyleri, ekokardiyografik olarak sol ventrikül diastol (LVEDD) ve sistol sonu çapları (LVESD) hacimleri, kardiyak debive ejeksiyon fraksiyonu (LVEF) parametreleri levosimendan tedavisi öncesi ve sonrasında elde edilerekkarşılaştırıldı.Bulgular: Dekompanze kalp yetmezliği varlığında, levosimendan tedavisi sol ventrikül diastol sonu çapı vehacmi, sol ventrikül sistol sonu hacmi, diastolik kan basıncı, serum NT-pro BNP düzeylerinde belirgin azalmayave sol ventrikül ejeksiyon fraksiyonunda artmaya neden olmuştur (p< 0.05). NT-pro BNP düzeyi ile solventrikül EF arasında anlamlı ters ilişki varlığı ortaya konmuştur (p
Akut dekompanze kalp yetmezliği varlığında levosimendan tedavisi esnasında NT-pro BNP düzeyi ve sol ventrikül ejeksiyon fraksiyonununprognostik etkisinin değerlendirilmesi
Aim: To evaluate the prognostic effect of serum NT-proBNP levels and left ventricular ejection fraction in patients who have acute decompansated heart failure and receive levosimendan treatment.Method: Fourteen patients (10 male (71,4 %), 4 female (28,6%)) with heart failure who have low cardiac output findings and unresponsive to intravenous and vasodilator therapy, functional capacity NHYA class IV were enrolled into the study. Clinical status, systolic (SBP) and diastolic blood (DBP) pressures as hemodynamic parameters, measurements of serum NT-proBNP, BUN, Cre, Na+, K+, AST, ALT, Hb, Htc levels; left ventricular end diastolic (LVEDD) and systolic (LVESD) diameters, end diastolic (LVEDV) and end systolic (LVESV) volumes, cardiac output and ejection fraction (LVEF) by echocardiographic evaluation were obtained before and after levosimendan infusionResults: Treatment with levosimendan in decompansated heart failure exerts significantly reduction in LVEDD, LVEDV, LVESV, DBP, serum NT-proBNP levels and increase in LVEF (p
