Abstract

Objective: Autonomic dysfunction is an important marker of prognosis in congestive heart failure (CHF) and may determine the symptoms and progression of CHF. The aim of our study was to investigate whether preserved autonomic function assessed by heart rate variability (HRV) analyses is related to absence of CHF symptoms despite prominently reduced systolic function. Methods: The study had a cross-sectional observational design. Fifty patients with left ventricular ejection fraction (EF) below 40% were enrolled. The patients were divided into two groups according to their CHF symptomatic status as Group 1 (NYHA functional class I, asymptomatic group) and Group 2 (NYHA functional class≥ II, symptomatic group). Plasma C-reactive protein (CRP), N-terminal proB-type natriuretic peptide (NT-proBNP) levels, echocardiographic parameters and HRV indices were measured while the patients were clinically stable in each group. Possible factors associated with the development of CHF symptoms were assessed by using multiple regression analysis. Results: Baseline clinical characteristics and left ventricular EF were similar in the two groups. Serum CRP (15±21 vs 7±18 mg/L, p=0.011) and NT-proBNP levels (1935±1088 vs 1249±1083 pg/mL, p=0.020) were significantly higher in symptomatic group. The HRV parameters (SDNN: 78±57 vs 122±42 ms, p=0.001; SDANN: 65±55 vs 84±38 ms, p=0.024; SDNNi: 36±41 vs 70±46 ms, p

Özet

Amaç: Otonomik disfonksiyon konjestif kalp yetersizliğinde (KKY) prognozun önemli bir belirleyicisidir ve KKY’nin semptomlarını ve ilerlemesini öngörebilir. Çalışmamızın amacı belirgin olarak azalmış sistolik fonksiyonu olan hastalarda kalp hızı değişkenliği (KHD) ile belirlenen korunmuş otonomik fonksiyonun KKY semptomlarının yokluğu ile ilişkili olup olmadığının araştırılmasıdır. Yöntemler: Çalışma gözlemsel ve enine- kesitli olarak planlandı. Sol ventrikül ejeksiyon fraksiyonu (EF) %40’ın altında 50 hasta çalışmaya alındı. Hastalar KKY semptomatik durumlarına göre; Grup 1 (NYHA sınıf I, asemptomatik grup) ve Grup 2 (NYHA sınıf>=II, semptomatik grup) olmak üzere iki gruba ayrıldılar. Hastaların plazma C-reaktif protein (CRP), N-terminal pro-B tip natriüretik peptit (NT-proBNP) düzeyleri, ekokardiyografik ölçümleri ve KHD parametreleri hastalar klinik olarak stabil iken ölçüldü. Konjestif kalp yetersizliği semptomlarının gelişimi ile ilgili olası faktörlerin bağımsızlığı çok değişkenli regresyon analizi ile değerlendirildi. Bulgular: Bazal klinik özellikler ve sol ventrikülün EF’si her iki grupta benzerdi. Serum CRP (15±21 ve 7±18 mg/L, p=0.011) ve NT-proBNP düzeyleri (1935±1088 ve 1249±1083 pg/mL, p=0.020) semptomatik grupta anlamlı olarak yüksekti. Kalp hızı değişkenliği parametreleri (SDNN: 78±57 ve 122±42 ms, p = 0.001; SDANN: 65±55 ve 84±38 ms, p=0.024; SDNNi: 36±41 ve 70±46 ms, p
