Abstract :Özet Amaç: Çalışmamızda konvansiyonel ekokardiyografi ile kalp fonksiyonları normal bulunan Duchenne Musküler Distrofili insert ignore into journalissuearticles values(DMD); hastaların miyokard fonksiyonlarının  pulse wave doku doppler görüntüleme insert ignore into journalissuearticles values(PWDDG); ve strain/strain rate insert ignore into journalissuearticles values(S/SR); ekokardiyografi aracılığıyla  ölçülmesi ve kontrol grubu ile karşılaştırılması amaçlandı. Materyal ve Metod: Bu çalışmada; ortalama yaşı 85,2 ± 38,4 ay olan 32 DMD’li erkek hasta ve 89 ± 38,9 ay olan 31 sağlıklı çocuk değerlendirildi. Demografik özellikler olgular ve kontrol grubunda değerlendirildi. Cinsiyet, yaş, vücut kitle indeksi, konvansiyonel  ekokardiyografi verileri, pulse wave doku Doppler görüntüleme insert ignore into journalissuearticles values(PW-TDI); verileri ve iki boyutlu insert ignore into journalissuearticles values(2D); longitudinal strain insert ignore into journalissuearticles values(LS); / longitudinal strain rate insert ignore into journalissuearticles values(LSR); ekokardiyografi değerleri karşılaştırıldı. Bulgular: Hasta ve kontrol grupları arasında kalp hızı bakımından istatistiksel olarak anlamlı fark saptandı insert ignore into journalissuearticles values(p<0.001); ve DMD’li grupta kalp hızı daha yüksekti. Ventriküler septumda bazal ölçümlerinde E m , S amplitüdü, izovolümetrik relaksasyon zamanı insert ignore into journalissuearticles values(İVRZ);, miyokard performans indeksi insert ignore into journalissuearticles values(MPİ); bakımından istatistiksel yönden anlamlı fark saptanırken insert ignore into journalissuearticles values(p<0,05);, sol ventrikü serbest duvar bazalindeki ölçümlerde de E m , S amplitüdü ve İVRZ bakımından istatistiksel yönden anlamlı fark bulundu insert ignore into journalissuearticles values(p<0,05);. Sol ventrikülün serbest duvar bazalindeki strain ve strain rate değerlerinde DMD’ligrup ve kontrol grubu arasında istatistiki yönden  anlamlı fark saptandı insert ignore into journalissuearticles values(p<0.001);. Yapılan apikal dört boşluk pozisyondaki global strain değerlerinde DMD’li grup ve kontrol grubu arasında istatistiki yönden anlamlı fark saptandı insert ignore into journalissuearticles values( p<0,001);.   Sonuç: Transtorasik ekokardiyografide normal aralık içinde sol ventrikül sistolik fonksiyon saptanan DMD`li asemptomatik hastalarda kontrol grubu ile karşılaştırıldığında sol ventrikül anterolateral duvarında LS ve LSR değerleri anlamlı olarak düşük bulundu. Anahtar kelimeler: Longitudinal strain, longitudinal strain rate, Duchenne musküler distrofi Abstract Aim: The goal of our study was to detect the left ventricular functions of duchenne muscular dystrophy insert ignore into journalissuearticles values( DMD); patients using , pulsed-wave tissue Doppler imaging insert ignore into journalissuearticles values(PW-TDI, longitudinal strain insert ignore into journalissuearticles values(LS); and longitudinal strain rate insert ignore into journalissuearticles values(LSR ); echocardiography who had normal left ventricular functions in standart echocardiography before, and to match them with the results of the control group. Material and Methods: İn this study compared 32 boys with DMD whose mean age was 85.2 ± 38.4 months were matched with 31 healthy males whose mean age was 89.0 ± 38.9 months. The following demographic features were assesed in both DMD patients  and controls: gender, age, body mass index, standard echocardiography parameters, pulsed-wave tissue Doppler imaging insert ignore into journalissuearticles values(PW-TDI); findings, and two-dimensional insert ignore into journalissuearticles values(2D); LS/LSR echocardiography measurements. Results: Asymptomatic boys with DMD were established to have high heart rate insert ignore into journalissuearticles values(p<0.001);. In the calculations performed from the base of the ventricular septum, statistically considerable differences were determined   between the Em, S amplitude and isovolumetric relaxation time insert ignore into journalissuearticles values(IVRT);, myocard performance index insert ignore into journalissuearticles values(MPI); values of the two groups insert ignore into journalissuearticles values(p<0.05);. In the evaluates made from the base of the left ventricular free wall, Em, S amplitude and IVRT, MPI values were demonstrated to be more considerably different insert ignore into journalissuearticles values(p<0.05);. The results of the LS and LSR measurements done from the base of the left ventricular free wall were considerably different between DMD and control group insert ignore into journalissuearticles values(p<0.001);, and in the global strain measurement performed from the four chamber apical position, considerable distinction was noted between the two groups insert ignore into journalissuearticles values(p<0.001);. Conclusion: In patients with DMD in whom standart echocardiography had assesed left ventricular systolic function within the normal range showed significantly lower LS and LSR values at the left ventricular anterolateral wall compared with the control group.
