Abstract

Objective: Levosimendan treatment has inotropic, anti-stunning, and cardioprotective effects in the setting of acute decompensated heart failure (HF). Among studies conducted on the treatment of heart failure, those based on the growth hormone axis are of particular interest. The aim of this study was to determine the value of baseline insulin-like growth factor 1 (IGF-I) measurements in predicting response to levosimendan treatment. Methods: The study population included patients on standard heart failure treatment who presented with functional capacity NYHA class 3-4 and left ventricular (LV) ejection fraction less than 35% were enrolled in this prospective, cohort study. Pre- and post-treatment symptoms of patients (72 hours after the completion of levosimendan infusion) and echocardiographic parameters were evaluated and blood samples were collected. Mann-Whitney U, Pearson Chi-square and Wilcoxon Sign Rank tests were used for statistical analysis. Correlations were determined using Spearman correlation analysis. Results: Thirty patients were enrolled in this study, 83.3% of whom were male and 16.7% were female, with a mean age of 62.6 ±10.1 years. Mean baseline IGF-I level was 106.9±47.0 μg/L. Statistically significant improvements were observed in NYHA class, mean brain natriuretic peptide (BNP) levels, LV ejection fraction and LV end-systolic volume values following treatment with levosimendan (respective pre-treatment and post-treatment values: 3.5±0.5 vs. 2.5±0.7, p

Özet

Amaç: Akut dekompanse kalp yetersizliğinde (KY) levosimendan tedavisi pozitif inotropik, “antistunning” ve kardiyoprotektif etkilidir. Kalp yetersizliği tedavisine yönelik yürütülen çalışmalar arasında büyüme hormonuna dayalı olanlar ilgi çekicidir. Levosimendan tedavisinden fayda görmede bazal insülin benzeri büyüme faktörü 1 (IGF-I)’in değerini araştırmak üzere çalışmayı planladık. Yöntemler: Bu prospektif kohort çalışmaya standart KY tedavisi altında NYHA sınıflamasına göre fonksiyonel kapasitesi 3-4 ve sol ventrikül (SV) ejeksiyon fraksiyonu
