Abstract

Doppler tissue imaging (DTI) is a new echocardiographic application which allows noninvasive assessment of left ventricular systolic and diastolic performance. Our aim was to determine the DTI parameters of patients before and after hemodialysis and to evaluate if this method was preload dependent or not. Our study included 40 chronic hemodialysis patients (17 female and 23 male) aged between 20 and 75 (mean 48 ± 14) years. Doppler echocardiography and pulsed DTI echocardiography were performed by the same physician to patients before and 1 hour later after the same hemodialysis session. We measured standard Doppler parameters (early diastolic (E) velocity, late diastolic (A) velocity, E/A ratio, deceleration time and isovolumic relaxation time) and tissue Doppler parameters (mitral annular early diastolic (e) velocity, mitral annular late diastolic (a) velocity, e/a ratio). Results: E and e waves decreased after hemodialysis in all patients (p45 years old both E and e waves decreased significantly (p0.05). In conclusion, both mitral inflow velocities and mitral annular velocities are volume-dependent in subjects over 45 years. However, in subjects under 45 years old, mitral annular velocity is independent of volume whereas mitral flow velocity is dependent. Diastolic functions may be evaluated with DTI in subjects under 45 years old.

Özet

Doku Doppler görüntüleme (DTI) yöntemi sol ventrikülün sistolik ve diyastolik fonksiyonlarını değerlendirmede kullanılan yeni ve invaziv olmayan bir tekniktir. Çalışmamızın amacı hemodiyaliz hastalarında diyaliz öncesi ve sonrası DTI parametrelerini ölçüp bu yeni yöntemin ön yükten ve yaştan etkilenip etkilenmediğini değerlendirmektir. Bu amaçla çalışmaya yaş ortalaması 48 ± 14 olan 40 hemodiyaliz hastası (17 kadın, 23 erkek) alındı. Hastalara aynı doktor tarafından hemodiyalizden önce ve hemodiyalizden 1 saat sonra Doppler ekokardiyografi ve pulsed DTI ekokardiyografi uygulandı. Standart Doppler parametreleri (erken diyastolik (E) dalga hızı, geç diyastolik (A) dalga hızı, E/A oranı, E deselerasyon zamanı, izovolumik relaksasyon zamanı) ile doku Doppler parametreleri (mitral anulus erken diyastolik dalga hızı (e), mitral anulus geç diyastolik dalga hızı (a), e/a oranı) ölçüldü. Sonuçlar: Tüm hastalar değerlendirildiğinde hemodiyaliz sonrası E ve e dalgalarındaki azalma anlamlıydı (sırasıyla p
