Abstract:

 

Purpose: The aim of our study was to compare the right ventricular systolic and diastolic functions and pulmonary artery pressure (PAP) in obese and non-obese patients with obstructive sleep apnea syndrome (OSAS) by tissue Doppler imaging (TDI) echocardiography.
Materials and Methods: This study was conducted with 69 patients, 34 obese and 35 non-obese, diagnosed moderate or severe OSAS by an overnight polysomnographic sleep study. In all patients, LV (left ventricle) and RV (right ventricle) size, left atial (LA) and RA (right atrial) dimensions, LV and RV systolic and diastolic functions and systolic PAPs were measured by M-mode, two-dimensional analysis, color flow Doppler and TDI.
Results: RV diastolic dysfunction was detected in both groups; this impairment was significantly higher in the obese group (lateral tricuspid late diastolic myocardial annular zone velocity A'a: 0.13 ± 0.03 in non-obese patients and 0.11 ± 0.04 in obese patients). The mean systolic PAP was significantly higher in obese patients (31.2±5.6, 27.1±5.8, respectively)
Conclusion: Obstructive Sleep Apnea Syndrome increases cardiovascular morbidity and mortality. In our study,left ventricul and right ventricul diastolic dysfunction was determined by tissue Doppler imaging  in patients with moderate and severe Obstructive Sleep Apnea Syndrome. Obesity contributes to this impairment regardless of Obstructive Sleep Apnea Syndrome .

 

Amaç: Çalışmamızın amacı, obez ve nonobez obstrüktif uyku apne sendromu (OUAS) hastalarında; doku doppler (DD) ekokardiyografi ile sağ ventrikül sistolik ve diyastolik fonksiyonlarının ve pulmoner arter basınçlarını (PAB) karşılaştırmaktı.
Gereç ve Yöntem: Çalışmamıza Uyku Laboratuarında polisomnografik inceleme yapılmış ve orta ya da ağır OUAS tanısı konmuş 35 nonobez ve 34 obez olmak üzere 69 hasta alındı. Tüm hastalarda M-mode, iki boyutlu inceleme, renkli akım Doppler ve Doku Dopler yardımıyla sol ventrikül ve sağ ventrikül boyutları, sol atrium (LA) ve sağ atrium (RA) boyutları, sol ventrikül ve sağ ventrikül sistolik ve diyastolik fonksiyonları ve sistolik PAB’ ları ölçüldü.
Bulgular: Her iki grupta da RV diyastolik fonksiyonlarında bozulma saptanmış olup, obez grupta anlamlı olarak daha fazla bozulma saptanmıştır (lateral triküspit annuler bölge geç diyastolik miyokardial hız A’a: nonobez hastalarda 0.13 ±0.03 ve obez hastalarda 0.11±0.04). Obez grupta ortalama sistolik PAB anlamlı olarak daha yüksek bulunmuştur (Sırasıyla 31.2±5.6 ve 27.1±5.8).
Sonuç: Obstrüktif Uyku Apne Sendromu kardiyovasküler morbidite ve mortaliteyi arttırır. Çalışmamızda orta ve ağır OUAS hastalarında doku doppler incelemesi ile SV ve RV diyastolik fonksiyonlarında bozulma saptanmıştır. Obezite OUAS‟tan bağımsız olarak bu bozukluğa katkıda bulunmaktadır.
