Abstract

Amaç: Kronik kalp yetmezliği olan hastalarda obstrüktif apne, santral apne ve Cheyne-Stokes solunumu (CSR) gibi uykuya bağlı solunum bozuklukları (SRBD) görülebilir. SRBD kalp yetmezliğinin prognozunu etkileyebilir.
Çalışmanın amacı, kalp yetmezliği olan hastalarda uykuya bağlı solunum bozukluklarını ortaya çıkarmak ve yeni bir tedavi modalitesi olarak adaptif servo-ventilasyonun (ASV) etkilerini göstermektir.
Gereç ve Yöntem: Bu prospektif çalışmaya kalp yetmezliği olan 32 hasta dahil edildi. Bir gece polisomnografi (PSG) yapıldı.
Bulgular: PSG sonuçlarına göre SRBD oranı %96.7 idi. Apne-hipopne indeksi (AHİ) >5 olan tüm hastalara sürekli pozitif hava yolu basıncı (CPAP) ve ASV titrasyonları önerildi. Demografik ve klinik özellikler, semptomlar, PSG bulguları, Cheyne-Stokes solunumu (CSR) varlığı, ekokardiyografi sonuçları kaydedildi. ASV titrasyonu öncesi ve sonrası solunum fonksiyon testleri, yürüme testleri yapıldı, transferrin ve pro-BNP konsantrasyonları belirlendi. AHİ'ye göre gruplarda 30 hastanın 18'inde şiddetli obstrüktif uyku apne sendromu (OUAS), 4'ü orta OUAS, 5'i hafif OUAS ve 2'si santral uyku apnesi (CSA) olarak tanımlandı. Obstrüktif apne, santral apne, AHİ, uyarılma ve SpO2 min değerlerinde, PSG ve CPAP, ASV titrasyonlarında anlamlı düzelme saptandı (sırasıyla p=0,001, p=0,016, p=0,001, p=0,015 ve p=0,008). ASV ile tüm CSR'lerin ortadan kaldırıldığı belirlendi. ASV titrasyonu pro-BNP sonrası yürüme mesafesi ve FVC değerleri anlamlı olarak değiştiği saptandı (sırasıyla p=0,036, p=0,018 ve p=0,018).
Sonuç: Sonuç olarak, CPAP ile devam eden ancak bir gecelik ASV uygulaması ile ortadan kaldırılan CSR ve santral apneler belirlendi. ASV’nin ayrıca pro-BNP'yi azalttığı ve FVC ve yürüme mesafesi değerlerini önemli ölçüde artırdığı ortaya konuldu.

Impact of Adaptive Servo-Ventilation in Heart Failure Patients

Abstract

Objective: Sleep-related breathing disorders (SRBD) as obstructive apnea, central apnea, and Cheyne-Stokes respiration (CSR), can be seen in patients with chronic heart failure. SRBD can influence the prognosis of heart failure. We aim to reveal sleep-related breathing disorders in heart failure patients and display the effects of adaptive servo-ventilation (ASV) as a new therapeutic modality.
Materials and Methods: In this prospective study, 32 patients with heart failure were included. One night polysomnography (PSG) was done.
Results: According to the results of PSG, the SRBD ratio was 96.7%. Continuous positive airway pressure (CPAP) and ASV titrations were offered to all patients with an apnea-hypopnea index (AHI) > 5. Demographics, clinical properties, symptoms, PSG findings, Cheyne-Stokes respiration (CSR), and echocardiography results were recorded. Before and after ASV titration, pulmonary function tests and walking tests were performed, and concentrations of transferrin and pro-BNP were recorded. In the groups according to the AHI, severe obstructive sleep apnea syndrome (OSAS) in 18 of 30 patients, four moderate OSAS, five mild OSAS, and two central sleep apnea (CSA). PSG and, CPAP, ASV titrations were done in 7 male and one female patient that obstructive apnea, central apnea, AHI, arousal, and SpO2 min values had significant improvements (p=0,001, p=0,016, p=0,001, p=0,015 and p=0,008 respectively). We determined all CSRs were eliminated with ASV. After ASV titration pro-BNP, walking distance, and FVC values changed significantly (p=0,036, p=0,018, and p=0,018 respectively).
Conclusion: As a result, we determined CSR and central apneas persisted with CPAP but were eliminated with a one-night ASV application. ASV also decreased pro-BNP and increased FVC and walking distance values significantly.
